3分钟关于全球变暖的英语演讲稿5篇3分钟关于全球变暖的英语演讲稿1In recent years do you think the weather suddenly turned hot had the cool autumn now almost until early October the hottest day in August has reached more than 40 degrees. These is different from normal vision we have ourselves toblame the curse.Today the term “global warming” has gradually penetrated into our life. The word sounds very academic even feel very far away from us so some people arenot. In fact the effects of global warming is beyond our imagination: global precipitation redistribution glaciers and permafrost melt rising sea levels andso on. Both harm the natural ecosystem balance more threatening human foodsupply and living environment.Now that you have aware of the dangers of global warming you should go to predict and improve it. Imagine if global warming is melting in the 21st century the global average temperature rising gradually so the next super storms thenext round of searing heat the next major natural disasters will happen? China? The United States? Japan? No one knows. The debate has ended. Scientists around the world agree points out that the earth’s average temperature has increased nearly 1 ℃. Due to all the early warning information human use of thousands of ships tens of thousands of the monitoring stations of the land and outer space satellite to monitor the earth together. Scientists will have the most advanced computer data input model to estimate the earth can face the future. Prediction results are worrying. Forty years later the Himalayan glaciers the water to the survival of millions of people are likely to disappear. The Greenland ice sheet could melt in 50 years. Currently half of the world’s biodiversity in the amazon rainforest but the rainforest is likely to turn into a piece of barren land bythe end of the century. Is likely to be the future of the world like in themovie “the day after tomorrow” tornado ice fracture the temperature fell sharply ice storms freezing rain earthquake flood tsunami volcanic eruption... This isnot a crazy fantasy if humans don’t stop destroying the environment it will become a reality!However in the warming is also good. Global warming on rice in heilongjiang province has played a large role.Just global warming to human future development is still the do more harm than good.In order to save the planet we should try to be: don’t open air conditioning use recycled paper environmental protection to leave the meat with nitrous oxide don’t use plastic bags R22 by bus; R22; Little drops of life. Actually it’s not difficult to environmental protection as long as you support environmental protection is the best gift you gave the planet.Thank you all!3分钟关于全球变暖的英语演讲稿2Many people believe that human activity is causing the earth’s temperature to rise. They say that this global warming will have dreadful consequences for our environment, such as drought and flooding.The earth’s temperature is rapidly changing. As a result there has been a lot of climate change such as heat waves, droughts and floods. Scientists believe that this is the result of human activity, which is polluting the Earth’s atmosphere. This could become a disaster if governments do not act to help prevent global warming. They can act in three ways; by supporting research, by making laws and by keeping the general public informed.Firstly, governments can support research. For example, they should encourage companies to develop vehicles that cause less pollution. They should also support alternative sources of electricity from wind and water rather than from oil and coal. As well, they should sponsor conferences to discuss the effects of greenhouse gas emissions and possible solutions to the problem.Secondly, they should make laws that limit the amount of greenhouse gases that companies can emit. Private companies should be rewarded for following these laws. They should also be punished for creating pollution.Finally, everybody is affected by global warming. Therefore, it isimportant that governments involve individuals in the problem solving process. For example they should encourage households to save as much energy as possible by using more efficient light bulbs or less hot water. They should also encourage the public to recycle, and this should be compulsory for everyone. Another way of saving energy is by public transport systems. Governments should spend money on public transport to make it as easy as possible for the public to save energy.In summary, it is clear that there are a lot of things that governments can do to prevent global warming. They should involve companies, support scientists and encourage individuals to protect the planet.3分钟关于全球变暖的英语演讲稿3global warming the gradual increase of the temperature of the earth’s lower atmosphere as a result of the increase in greenhouse gases since the Industrial Revolution.The temperature of the atmosphere near the earth’s surface is warmed through a natural process called the greenhouse effect. Visible shortwave light comes from the sun to the earth passing unimpeded through a blanket of thermal or greenhouse gases composed largely of water vapor carbon dioxide methane nitrous oxide and ozone. Infrared radiation reflects off the planet’s surface toward space but does not easily pass through the thermal blanket. Some of it is trapped and reflected downward keeping the planet at an average temperature suitable to life about 60°F (16°C).Growth in industry agriculture and transportation since the Industrial Revolution has produced additional quantities of the natural greenhouse gases plus chlorofluorocarbons and other gases augmenting the thermal blanket. It is generally accepted that this increase in the quantity of greenhouse gases is trapping more heat and increasing global temperatures making a process that has been beneficial to life potentially disruptive and harmful. During the past century the atmospheric temperature has risen 1.1°F (0.6°C) and sea level has risen several inches. Some projected longer-term results of global warming include melting of polar ice with a resulting rise in sea level and coastal flooding; disruption of drinking water supplies dependent on snow melts; profound changes in agriculture due to climate change; extinction of species as ecological niches disappear; more frequent tropical storms; and an increased incidence of tropical diseases.Improved automobile mileage reforestation projects energy efficiency in construction and national support for mass transit are among relatively simpler adjustments that could significantly lower U.S. production of greenhouse gases. More aggressive adjustments include a gradual worldwide shift away from the use of fossil fuels the elimination of chlorofluorocarbons and the slowing of deforestation by restructuring the economies of developing nations. In 20__ theBush administration proposed several voluntary measures for slowing the increase in instead of reducing emissions of greenhouses gases.3分钟关于全球变暖的英语演讲稿4Global WarmingThere is little doubt that the planet is warming. Over the last century,the planets temperature has risen by around 1 degree fahrenheit (0.6 of a degree celsius). The warmest since the mid 1800’s was the 1990s. The hottest years recorded were 1997, 1998, 20xx, 20xx, 20xx.The United Nations panel on climate change projects that the global temperatures will rise 3-10 degrees fahrenheit by the century’s end - enough to have the polar caps all but melted. If the ice caps melt, a vast majority of our countries borders will be under water. Monuments and great buildings, as well as homes and lives will be under water, including New York City.So now we know what some of the causes are for global warming, how can weas individuals do our part to help save the planet?The answer is simpler than you may think. You don’t have to go miles away from home to protest, or spend masses of money. If you try to follow the few simple steps that I shall now give you, you will have started to help usall.Firstly, plant a tree. This could be easier than it sounds. Join or helpout a local wildlife group and ask to plant a tree. Trees, when fully grown,will help keep the planet cooler. On the same point, you could protest against the demolition of the rainforests. This is the same principle, we need the trees to cool our planet and yet they are chopping them down to create roads or homes.Something as simple as walking instead of taking the car will help reduce pollution. As well as stopping pollution, you are giving yourself exercise, something important for our bodies. So the next time you get into your car, or your motorbike, think - do I have to make this journey by vehicle or can I walk?When you are at home, and your getting a little cold. Put a jumper on anddo not adjust the heating. The extra heat produced by our homes also affects the planet. So try wearing an extra layer in winter.If possible, buy your fruit and vegetables from local suppliers. And try toavoid imported goods. The more foreign food that we import the more pollution from aeroplanes and boats it will create.Keeping to the speed limit can also help the environment. The more you speed the more petrol you are going to use, making the pollution higher. Also, SUV’s make about six times their own weight in CO2 each year. A small efficient diesel car covering the same distance not only uses much less fuel; it makes two thirds less.If possible use solar energy, after all it is free; all you need to buy is the equipment. You can get much of your hot water and heating from the sun and even generate electricity.Reduce, reuse and recycle. Only buy what you need; don’t stock the cupboards with things you may or may not use. Reuse whatever you can, like containers and paper, and recycle what you cannot reuse. It really is as simple as that.Finally turning off unused sources of power such as televisions and heaters will help the environment, as well as save you money.If everybody stuck to these rules, we would be doing a great thing by protecting the earth. So please take into consideration what I have said, andtry to do your part. After all, it will be our next generation that will feel the effects.3分钟关于全球变暖的英语演讲稿5The topic of global warming is attracting the attentions of countries all over the world. This global warming is on such a scale that it will wreak havoc on both poor and rich countries. It could even make large sections of the earth uninhabitable.What have caused global warming? The theory and evidence strongly suggest that human-related emissions of carbon into the atmosphere is causing, and will in the future cause, significant global warming.How we should fight global warming? We should be taking active steps now to curb emissions and we should be engaging in international co-operation to do so.A simple natural way to fight global warming is to have escalating Taxes on carbon emissions. There is a simple reason why this is the ideal remedy: carbon emissions into the atmosphere constitute a nuisance to everybody on the planet; so those who make this nuisance should pay for their actions. A furtherrecommendation is that there should be large-scale government support for research into new technology that will reduce carbon emissions.China is the rising economic star; and if it also wants to assert world leadership status, it is a good xxrtunity for China to show the world that it has a moral commitment and the will to fight global warming.。
台风 倡议书余环流和季风影 英语作文
台风倡议书余环流和季风影英语作文全文共3篇示例，供读者参考篇1The Profound Impact of Atmospheric Phenomena on Our WorldAs students of the natural world, we are constantly in awe of the intricate dance between the various components of Earth's delicately balanced systems. Among the most captivating and powerful of these forces are the atmospheric phenomena that shape our weather patterns and climates. In this essay, we will delve into the realms of typhoons, westerly winds, and monsoons, exploring their intricate mechanisms, far-reaching effects, and the profound ways in which they influence our lives.Typhoons: Nature's Powerful TempestsTyphoons, also known as hurricanes or cyclones, are nature's most formidable storms, born from the perfect alignment of atmospheric conditions. These colossal vortices of wind and rain can span hundreds of miles in diameter, unleashing torrential downpours, storm surges, and winds that can reach catastrophic speeds.At their core, typhoons are fueled by the immense energy released when warm, moist air from the ocean's surface condenses into towering thunderstorms. As these storms organize and intensify, they develop a characteristic spiral structure, with an eye at the center – a relatively calm region surrounded by the storm's most violent winds and heaviest precipitation.While typhoons can be awe-inspiring in their raw power, they also pose significant risks to coastal communities and ecosystems. Their destructive force can level buildings, uproot trees, and cause widespread flooding, leading to loss of life and extensive property damage. Moreover, the long-term effects of these storms can disrupt local economies, infrastructure, and agricultural production, leaving lasting scars on the affected regions.Despite their fearsome reputation, typhoons play a crucial role in Earth's overall climate system. They act as a powerful mechanism for redistributing heat and moisture across the planet, helping to maintain the delicate balance that sustains life as we know it.Westerly Winds: The Perpetual MoverWesterly winds, also known as prevailing westerlies, are a perpetual force that encircles the mid-latitudes of both hemispheres. These winds, driven by the rotation of the Earth and the uneven heating of the planet's surface, play a crucial role in shaping weather patterns and influencing global climate.At their core, westerly winds are the result of the Earth's rotation and the unequal distribution of solar energy across its surface. As warm air rises near the equator and cooler air sinks at the poles, a complex system of atmospheric circulation is set in motion. This circulation creates bands of prevailing winds, with the westerlies being one of the most prominent.These winds have a profound impact on weather patterns, transporting moisture and influencing the formation and movement of weather systems. They are responsible for the progression of many mid-latitude cyclones, which can bring heavy precipitation, strong winds, and dramatic temperature fluctuations to affected regions.Beyond their immediate effects on weather, westerly winds also play a crucial role in global climate patterns. They help distribute heat and moisture across vast distances, influencing the formation of deserts, rainforests, and other biomes.Additionally, they influence ocean currents, which in turn shape marine ecosystems and regulate global temperatures.Monsoons: The Seasonal ShiftMonsoons are a remarkable seasonal phenomenon, characterized by a dramatic reversal in wind patterns and associated changes in precipitation. These massive wind systems are driven by the differential heating of land and ocean masses, creating a cyclical pattern that profoundly impacts vast regions of the world.During the summer months, intense heating over continental landmasses causes air to rise, drawing in moist air from the surrounding oceans. This inflow of moisture-laden winds brings heavy rainfall to areas that would otherwise experience dry conditions. Conversely, in the winter, the cooler land masses cause air to sink, creating dry conditions and a reversal of wind patterns.Monsoons are particularly prominent in regions such as South and Southeast Asia, West Africa, and parts of North America. In these areas, the seasonal influx of moisture is crucial for agriculture, replenishing water supplies, and sustaining fragile ecosystems. However, monsoons can also bringdevastating floods, landslides, and other natural disasters, highlighting the delicate balance that must be maintained.Beyond their direct impact on weather and climate, monsoons have played a pivotal role in shaping human civilizations throughout history. Many ancient societies developed intricate systems for harnessing and managing monsoon rains, enabling them to thrive in otherwise inhospitable environments. Today, billions of people continue to rely on monsoon patterns for their livelihoods and well-being.Interconnected Forces, Intertwined FatesAs we have explored, typhoons, westerly winds, and monsoons are intricate and powerful atmospheric phenomena that shape our world in profound ways. Yet, these forces do not exist in isolation; they are interconnected components of a vast and intricate system that governs our planet's climate and weather patterns.The interactions between these phenomena are complex and far-reaching. Westerly winds can influence the formation and movement of typhoons, while monsoon patterns can be disrupted by the intense heat and moisture redistribution caused by these storms. Furthermore, changes in global climate patterns, driven by factors such as greenhouse gas emissions anddeforestation, can alter the behavior and intensity of these atmospheric phenomena, leading to cascading effects on ecosystems, economies, and human societies.As students of the natural world, it is our responsibility to deepen our understanding of these intricate processes and to appreciate the delicate balance that sustains life on our planet. By studying these atmospheric phenomena, we not only gain insights into the fundamental workings of our environment but also equip ourselves with the knowledge necessary to mitigate the risks they pose and to adapt to the changing realities of our world.In a era of unprecedented global challenges, from climate change to resource scarcity, our ability to comprehend and manage the complex interplay between atmospheric forces will be paramount. Through continued research, international cooperation, and a profound respect for the natural world, we can strive to coexist harmoniously with these awe-inspiring phenomena, harnessing their power while mitigating their destructive potential.Ultimately, the study of typhoons, westerly winds, and monsoons is not merely an academic pursuit; it is a journey into the very heart of the systems that sustain life on ourextraordinary planet. By embracing this knowledge, we can deepen our connection to the natural world and chart a course towards a future where humanity and nature can thrive in harmony, guided by the wisdom gleaned from the skies above.篇2The Intricacies of Tropical Cyclone Formation: A Compelling Interplay of Walker Circulation and MonsoonsAs a student fascinated by the intricate workings of our planet's atmospheric phenomena, I find myself drawn to the captivating world of tropical cyclones. These awe-inspiring weather systems, with their immense power and far-reaching impacts, have long been a subject of intense study and curiosity. However, what truly piques my interest is the intricate interplay between the Walker Circulation and monsoon patterns, which plays a pivotal role in the formation and behavior of these cyclonic behemoths.To delve into the heart of this topic, we must first understand the fundamentals of the Walker Circulation. Named after the renowned British meteorologist, Sir Gilbert Walker, this atmospheric circulation pattern is characterized by a series of ascending and descending air currents that span the tropicalregions of the Pacific Ocean. It is a colossal, east-west overturning of air, driven by the temperature differences between the warmer western Pacific and the cooler eastern Pacific.At the core of the Walker Circulation lies a powerful engine fueled by the release of latent heat from condensing water vapor. As warm, moist air rises over the western Pacific, it cools and condenses, releasing vast amounts of heat energy. This process drives the formation of towering thunderstorms and heavy precipitation in regions like Indonesia and the western Pacific warm pool. Conversely, as the air descends over the cooler eastern Pacific, it warms and dries, suppressing cloud formation and precipitation.It is within this delicate dance of rising and falling air masses that the seeds of tropical cyclones are sown. When the Walker Circulation weakens or reverses its pattern, the atmospheric conditions become ripe for the development of these formidable storms. A weakened or reversed Walker Circulation can disrupt the usual patterns of convection and atmospheric stability, allowing pockets of warm, moist air to persist and intensify over the tropics.But the Walker Circulation is not the sole orchestrator of this meteorological symphony. The monsoon systems, those gigantic seasonal wind shifts that sweep across various regions of the globe, also play a pivotal role in shaping the conditions conducive to tropical cyclone formation. Monsoons are driven by the uneven heating of land and ocean surfaces, resulting in a remarkable annual reversal of wind patterns.During the summer months, the intense heating of continental landmasses creates vast areas of low pressure, drawing in moisture-laden air from the surrounding oceans. This influx of humid air, coupled with the rising motion induced by the low-pressure systems, sets the stage for the development of thunderstorms and, potentially, tropical cyclones.The interplay between the Walker Circulation and monsoon patterns becomes particularly intriguing in regions like the western Pacific and the Indian Ocean basins. In these areas, the interaction between the two systems can either amplify or mitigate the conditions favorable for tropical cyclone formation. When the Walker Circulation is in its normal state, with ascending air over the western Pacific and descending air over the eastern Pacific, it can reinforce the monsoon patterns,leading to increased convection and potential cyclone development.However, when the Walker Circulation weakens or reverses, it can disrupt the typical monsoon flow, altering the distribution of moisture and atmospheric instability. This disruption can either enhance or suppress tropical cyclone activity, depending on the specific regional dynamics and timing of the monsoon patterns.Moreover, the relationship between the Walker Circulation and monsoons is not a one-way street. Just as the Walker Circulation can influence monsoon patterns, the reverse is also true. Strong monsoon systems can modulate the strength and position of the Walker Circulation, leading to fluctuations in its intensity and potentially triggering atmospheric instabilities that favor tropical cyclone formation.This intricate dance between the Walker Circulation and monsoons is further complicated by the influence of other large-scale atmospheric and oceanic phenomena, such as the El Niño-Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD). These oscillating patterns of sea surface temperatures and atmospheric pressure can significantly impact the strength and behavior of both the Walker Circulation and monsoon systems,creating a complex web of interactions that shape the fate of tropical cyclones.As a student captivated by these intricate atmospheric dynamics, I find myself constantly drawn to the pursuit of understanding the intricate interplay between the Walker Circulation, monsoons, and tropical cyclone formation. It is a quest that demands a multidisciplinary approach, integrating knowledge from meteorology, oceanography, and climate science.Through rigorous study and analysis of observational data, numerical models, and theoretical frameworks, we can unlock the secrets of this intricate dance, unraveling the complex interactions that govern the birth, evolution, and behavior of these awe-inspiring weather phenomena.Yet, this pursuit extends far beyond mere academic curiosity. By enhancing our comprehension of the factors influencing tropical cyclone formation, we can improve our ability to predict and prepare for these potentially destructive events. Accurate forecasting and timely warnings can save countless lives and mitigate the devastating impacts of these storms on communities, infrastructure, and economies.Furthermore, as our planet grapples with the escalating challenges of climate change, understanding the intricate connections between the Walker Circulation, monsoons, and tropical cyclones becomes increasingly crucial. Climate models suggest that alterations in global temperature patterns and ocean circulations could profoundly impact these atmospheric phenomena, potentially altering the frequency, intensity, and trajectories of tropical cyclones.As a student passionate about this field, I am driven by the desire to contribute to this vital area of research. Through collaboration with esteemed scientists, engagement with cutting-edge technologies, and a relentless pursuit of knowledge, I aspire to unravel the mysteries that lie at the heart of this intricate dance, and in doing so, play a role in safeguarding our communities and shaping a more resilient future.The path ahead is undoubtedly challenging, but the rewards of unlocking the secrets of tropical cyclone formation and its intricate ties to the Walker Circulation and monsoons are immeasurable. It is a journey that promises to deepen our understanding of our planet's atmospheric dynamics, enhance our predictive capabilities, and ultimately, contribute to theglobal effort to mitigate the impacts of these awe-inspiring yet formidable weather events.篇3The Interwoven Dance of Typhoons, Extratropical Transition, and MonsoonsAs a student fascinated by the intricate workings of our atmosphere, I find myself drawn to the captivating interplay between typhoons, their extratropical transition, and the profound influence of monsoon systems. These meteorological phenomena, once perceived as distinct entities, are intricately intertwined, forming a intricate choreography that shapes our weather patterns and influences countless lives across the globe.Typhoons, those formidable storms born in the warm tropical waters, are the protagonists of this atmospheric ballet. Fueled by the ocean's heat and the Earth's rotation, they whirl across vast expanses, carrying within their spiraling bands immense energy and potential for destruction. Yet, their journey does not end with their landfall or dissipation over cooler waters; instead, it often transitions into a new phase, one that defies the conventional boundaries of tropical cyclones.Enter the extratropical transition, a metamorphosis that transforms these once purely tropical systems into hybrid storms, blending characteristics of both tropical and extratropical cyclones. As typhoons venture into higher latitudes, they encounter the stark temperature contrasts and intense wind shear that define the midlatitude regions. In this clash of air masses, the typhoon's structure begins to evolve, shedding its symmetric shape and warm core, while acquiring the asymmetric features and cold core characteristic of extratropical cyclones.This transition is not merely a physical transformation but a dance of energy exchange, as the typhoon's remnants interact with the prevailing weather systems of the midlatitudes. The residual heat and moisture from the dissipating typhoon can reinvigorate existing extratropical systems, breathing new life into their circulation and enhancing their intensity. Conversely, the extratropical systems can also influence the remnants of the typhoon, altering its trajectory and modulating its strength.It is within this intricate choreography that the monsoon systems make their grand entrance, playing a crucial role in shaping the typhoon's life cycle and subsequent extratropical transition. Monsoons, those seasonal reversals of wind patterns driven by the differential heating of land and ocean, create anenvironment ripe for the formation and sustenance of tropical cyclones.During the peak monsoon months, the warm,moisture-laden air streaming inland from the oceans provides the ideal breeding ground for typhoon genesis. The convergence of these monsoon winds, coupled with favorable atmospheric conditions, can spawn and nurture these powerful storms, fueling their growth and intensification.However, the influence of monsoons extends far beyond the initial stages of typhoon development. As these storms traverse the vast ocean basins, their trajectories and intensities are often guided by the prevailing monsoon patterns. The strong winds associated with monsoon systems can steer typhoons along specific paths, either deflecting them away from land masses or propelling them towards densely populated coastal regions.Moreover, the extratropical transition of typhoons is intimately linked to the evolution of monsoon systems. As the seasons transition and the monsoon patterns shift, the atmospheric conditions that once favored the typhoon's tropical characteristics begin to wane. The encroaching midlatitude weather systems, influenced by the changing monsoon patterns,facilitate the typhoon's extratropical transition, guiding it through this metamorphosis.This intricate dance between typhoons, extratropical transition, and monsoons has far-reaching consequences that extend beyond the realms of meteorology. The impacts of these interconnected phenomena reverberate across diverse sectors, from agriculture and infrastructure to emergency management and disaster preparedness.In regions prone to typhoon landfalls, the extratropical transition of these storms can significantly prolong their lifespan and extend their reach, bringing heavy rainfall, damaging winds, and coastal flooding to areas far removed from the initial tropical cyclone. This extended threat requires heightened vigilance and proactive measures to safeguard lives and property.Furthermore, the interplay between typhoons and monsoons can have profound implications for water resource management and agricultural planning. The intense rainfall associated with these systems can replenish reservoirs and aquifers, alleviating drought conditions in some regions, while excessive precipitation can lead to devastating floods in others. Understanding these intricate relationships is crucial fordeveloping effective strategies to mitigate risks and optimize resource utilization.As a student immersed in the study of atmospheric sciences, I am constantly in awe of the intricate tapestry woven by these interconnected phenomena. The dance of typhoons, their extratropical transition, and the influence of monsoon systems is a testament to the complexity and dynamism of our planet's weather systems.To fully comprehend and accurately predict the trajectories and impacts of these events, we must embrace a holistic approach, recognizing the interdependencies that govern their evolution. By unraveling the intricacies of their interactions, we can enhance our preparedness, improve forecasting capabilities, and ultimately, foster a deeper understanding of the intricate choreography that shapes our world.It is through this lens of interconnectedness that we can truly appreciate the grandeur of nature's symphony, where typhoons, extratropical transition, and monsoons are not mere isolated phenomena but harmonious movements in a grander composition – a composition that continues to captivate and inspire generations of atmospheric scientists like myself.。

定义A tornado is "a violently rotating column of air, in contact with the ground, either pendant from a cumuliform cloud or underneath a cumuliform cloud, and often (but not always) visible as a funnel cloud"。
A multiple-vortex tornado is a tornado that contains several vortices rotating around, inside of, and as part of the main vortex.The only times multiple vortices may be visible are when the tornado is first forming or when condensation and debris is balanced enough so that subvortices are apparent without being obscured.A waterspout is defined by the National Weather Service as a tornado over water.They form at the bases of cumulus congestus clouds over tropical and subtropical waters. They have relatively weak winds, smooth laminar walls, and typically travel very slowly. They occur most commonly in the Florida Keys and in the northern Adriatic Sea. In contrast, tornadic waterspouts are stronger tornadoes over water.FormWarm moist air shoots upward meeting colder, dryer air. Warm moist air is lighter than the cold dry air making for a strong updraft within the thunderstorm. As the warm moist air rises, it may meet varying wind directions at different altitudes.If these varying winds are staggered in just the right manner with sufficient speed, they will act on the upward rising air, spinning it like a top. This would be similar to spinning a pencil held between your hands with your palms facing each other, moving your hands in opposite directions. The storm will begin to show visible rotation, often forming a wall cloud. Inside the storm these spinning winds can begin the formation of a tornado. On the outside of the thunderstorm rotation might be visible as in this photo and here. Only about 30 percent of mesocyclones actually produce a tornado, but about 95 percent produce severe weather. Most of our information about the inside of a tornado-generating thunderstorm comes from data gathered by Doppler radar. The illustration (1a) would be an example of how a tornado would typically form in this type of thunderstorm.1) the instability of the atmosphere to produce a strong updraft , because of the rapids in the largest transit airflow, it is further strengthened.2) due to the updraft begins to rotate in the middle of the troposphere, the formation of the meso-scale cyclone with wind speed and direction are in the vertical direction shear interaction. 3)With the development of mesoscale cyclones to the ground and upward stretch itself thinner and enhanced. At the same time, a small area of enhanced auxiliary co-nascent tornado is formed inside the cyclone, resulting in the same process of the cyclone, the formation of the tornado core.4) different the tornadoes core rotation and cyclones, its strength is enough to make the tornado has been extended to the ground. Development of the vortex reaches the ground level, the surfacepressure sharply decreased, a sharp increase in surface wind speed, the formation of tornadoesharmThere are many damages. the car was blown over, trees were uprooted, roofs and walls were blown away with this series Tornado damagePreventat home, be sure to stay away from doors, windows and housing peripheral wall, hide your head squat tornado direction opposite walls or small rooms. To escape the tornado safe place is the basement or semi-basement.The opposition having an affair tornado, you should find the nearest low-lying land volts on the ground, but to stay away from trees, poles , so as not smashed, pressure and electric shock .car go out to encounter a tornado, do not drive a car to escape, and do not in the car to avoid car tornado almost no defense, you should immediately leave the car to the low-lying ground to escape.。

Title: The Fury of Nature: Tornadoes。
Introduction:Tornadoes are one of the most awe-inspiring yet terrifying forces of nature. These violent windstorms, characterized by rotating columns of air, can cause widespread destruction in a matter of minutes. Understanding the science behind tornado formation, their impact on communities, and measures for protection is crucial in mitigating their devastating effects.Body:1. Formation and Characteristics of Tornadoes:Tornadoes typically develop within severe thunderstorms known as supercells. These storms are characterized by strong updrafts and downdrafts, creating an environment conducive to tornado formation. As warm, moist air rises and meets cooler, denser air, it caninitiate a rotating column called a mesocyclone. When this mesocyclone tightens and descends, it forms the funnel cloud that we recognize as a tornado.2. Impact on Communities:The impact of tornadoes on communities can be catastrophic. The high winds, often exceeding 200 miles per hour, can uproot trees, tear apart buildings, and toss vehicles like toys. The aftermath of a tornado includes widespread damage to infrastructure, homes, and businesses, leading to significant economic losses. Additionally, tornadoes can cause injuries and fatalities, highlighting the urgent need for effective disaster preparedness and response strategies.3.

超强台风 英语作文
超强台风英语作文Super Typhoon。
A typhoon is a powerful tropical cyclone that formsover warm ocean waters. It is characterized by strong winds, heavy rainfall, and storm surges. Among the different types of typhoons, a super typhoon is the most intense and destructive. In this essay, we will explore the characteristics of a super typhoon and its impact on the affected areas.A super typhoon is defined as a tropical cyclone with maximum sustained winds of at least 240 kilometers per hour (150 miles per hour). These storms are often accompanied by torrential rains, which can cause widespread flooding and landslides. The strong winds associated with a supertyphoon can cause extensive damage to buildings, infrastructure, and vegetation. In addition, the stormsurge generated by the typhoon can result in coastalflooding and erosion.The formation of a super typhoon requires specific conditions. Firstly, the ocean waters must be warm, usually with temperatures above 26 degrees Celsius (79 degrees Fahrenheit), to provide the necessary energy for the storm. Secondly, there must be a low-pressure system in the atmosphere, which allows the warm air near the ocean surface to rise and form clouds. As the air continues to rise, it creates a powerful updraft that fuels the typhoon. Finally, there must be a lack of wind shear, which is the change in wind speed or direction with height. Wind shear can weaken or disrupt the formation of a typhoon.Once a super typhoon forms, it can travel across vast distances, affecting multiple countries and regions. The impact of a super typhoon can be devastating. The strong winds can uproot trees, tear off roofs, and even topple buildings. The heavy rainfall can cause rivers to overflow and trigger flash floods. The storm surge can inundate coastal areas, leading to the loss of lives and destruction of homes. The combination of these factors can result in significant economic losses and human suffering.In recent years, several super typhoons have made headlines for their destructive power. One such example is Super Typhoon Haiyan, which struck the Philippines in 2013. With wind speeds reaching up to 315 kilometers per hour (195 miles per hour), it was one of the strongest typhoons ever recorded. The storm surge caused by Haiyan was particularly devastating, resulting in the loss of thousands of lives and displacing millions of people.To mitigate the impact of super typhoons, it is crucial for governments and communities to be well-prepared. Early warning systems can provide timely information about the approaching storm, allowing people to evacuate and take necessary precautions. Infrastructure should be built to withstand strong winds and flooding. Education and awareness campaigns can help people understand the risks and teach them how to respond in an emergency.International cooperation is also essential, as super typhoons can affect multiple countries and require coordinated efforts for response and recovery.In conclusion, a super typhoon is a powerful and destructive tropical cyclone. With its strong winds, heavy rainfall, and storm surges, it can cause extensive damage to the affected areas. To minimize the impact, it iscrucial to be well-prepared and take necessary precautions. By working together, we can better protect ourselves and our communities from the devastating effects of super typhoons.。
