天气的英文短文

The weather is a set of all the phenomena in a given atmosphere at a given time. It also includes interactions with the hydrosphere. The term usually refers to the activity of these phenomena over short periods (hours or days), as opposed to the term climate, which refers to the average atmospheric conditions over longer periods of time. When used without qualification, "weather" is understood to be the weather of Earth.Weather most often results from temperature differences from one place to another. On large scales, temperature differences occur because areas closer to the equator receive more energy per unit area from the Sun than do regions closer to the poles. On local scales, temperature differences can occur because different surfaces (such as oceans, forests, ice sheets, or man-made objects) have differing physical characteristics such as reflectivity, roughness, or moisture content.Surface temperature differences in turn cause pressure differences. A hot surface heats the air above it and the air expands, lowering the air pressure. The resulting horizontal pressure gradient accelerates the air from high to low pressure, creating wind, and Earth's rotation then causes curvature of the flow via the Coriolis effect. The simple systems thus formed can then display emergent behaviour to produce more complex systems and thus other weather phenomena. Large scale examples include the Hadley cell while a smaller scale example would be coastal breezes.The strong temperature contrast between polar and tropical air gives rise to the jet stream. Most weather systems in the mid-latitudes are caused by instabilities of the jet stream flow (see baroclinity). Weather systems in the tropics are caused by different processes, such as monsoons or organized thunderstorm systems.Because the Earth's axis is tilted relative to its orbital plane, sunlight is incident at different angles at different times of the year. In June the Northern Hemisphere is tilted towards the sun, so at any given Northern Hemisphere latitude sunlight falls more directly on that spot than in December (see Effect of sun angle on climate). This effect causes seasons. Over thousands to hundreds of thousands of years, changes in Earth's orbital parameters affect the amount and distribution of solar energy received by the Earth and influence long-term climate (see Milankovitch cycles).On Earth, common weather phenomena include such things as wind, cloud, rain, snow, fog and dust storms. Less common events include natural disasters such as tornadoes, hurricanes and ice storms. Almost all familiar weather phenomena occur in the troposphere (the lower part of the atmosphere). Weather does occur in the stratosphere and can affect weather lower down in the troposphere, but the exact mechanisms are poorly understood.[1]The atmosphere is a chaotic system, so small changes to one part of the system can grow to have large effects on the system as a whole. This makes it difficult to accurately predict weather more than a few days in advance, though weather forecasters are continually working to extend this limit through the scientific study of weather, meteorology. It is theoretically impossible to make useful day-to-day predictions more than about two weeks ahead, imposing an upper limit to potential for improved prediction skill.[1] Chaos theory says that the slightest variation in the motion of the ground can grow with time. This idea is sometimes called the butterfly effect, from the idea that the motions caused by the flapping wings of a butterfly eventually could produce marked changes in the state of the atmosphere. Because of this sensitivity to small changes it will never be possible to make perfect forecasts, although there still is much potential for improvement.The sun and oceans can also affect the weather of land. If the sun heats up ocean waters for a period of time, water can evaporate. Once evaporated into the air, the moisture can spread throughout nearby land, thus making it cooler. 这应该差不多了。

Weather Weather changes with seasons--cold with snow in winter, hot with rain in summer and mild with sunlight in spring and autumn.I like the weather with sunshine because sunny weather make people pleasant and happy. But I really don't like the weather in Beijing very much for it is very dry and windy in autumn, and this is the city's typical weather. Yet the weather I like most in Beijing is spring and summer. In spring flowers bloom and trees turn green and everything are full of vigor.In summer the city is decorated with flowers and green coverings almost everywhere.I think the best weather for Beijing 2008 Olympic Games is the season of late summer and early autumn. So I hope it is going to be held in this season.I also agree that usually sunny weather can make people happy while rainy or cloudy or windy weather can make people in low-spirit for people tend to be more active and comfortable in sunny weather.So nobody really likes windy and rainly weather and instead almost all like sunny one. 翻译：天气 天气随季节变化，冬天寒冷下雪，夏天炎热下雨，春秋温和而阳光充足。我喜欢晴朗的天气因为明媚的阳光使人心情舒畅。但我却不太喜欢北京的秋天，干燥而风大是北京的典型天气。我最喜欢北京的春天和夏天。春天，百花盛开，树木变绿，一切都充满了生机活力。夏天，整个北京到处点缀着鲜花和绿地。我认为2008年北京举办奥运会的最好季节是夏秋之交，真希望能在这个时候举办盛会。我同意这样的观点：晴朗的天气使人愉悦，而阴天，下雨或刮风的天气使人心情压抑，因为晴朗的天气里人们会觉得活跃和舒适。因此，没有人喜欢刮风下雨天，而是都喜欢阳光明媚的天气。

Today is sunday.We'll go to the park. Today is sunny. The sky is blue. The air is fresh.We can fly the kite.

多雨雪天气长江中下游地区有明显降水 受活动频繁的弱冷空气影响,未来三天,北方大部地区气温起伏明显。内蒙古东部、东北、云南、贵州西部等地将以晴或多云天气 More rainy and snowy weather in the middle and lower reaches of Yangtze River have significantly frequent precipitation events by weak cold air, the next three days, temperatures in most areas north obvious ups and downs. Eastern Inner Mongolia and northeast China, Yunnan, Guizhou and the western region, such as weather will be sunny or cloudy Hunan Weather Hunan’s climate is typified by warm summers, mild winters, and moderate rainfall spread across the year. The proximity to the ocean results in less extreme weather conditions than places more inland. Sydney is generally a comfortable place to visit all year around, although the summer period from December to February is the hottest time of year and can be quite humid at times with the occasional heavy rainfall. Sydney’s summer temperature is usually pleasant, although on occasions can get severely hot with temperatures over 40°C not unheard of. The winter in Sydney is mild, with temperatures very occasionally dropping below 5°C. Spring and autumn are both popular times of year to visit, with some rainfall possible, but usually the rain clears quite quickly. Sydney’s climate is a big attraction for many people and with over 300 sunny days a year, but no really extreme conditions, it’s not hard to see why.望采纳！

展开自己的想象，想一想自己国家今天的天气怎么样，写一写吧！

写作思路及要点：围绕天气预报

Good morning ! Here’s the weather report for some big cities in the world . Beijing is cloudy . It’s very cold, so wear warm clothes when you go out .

In Hong Kong there’s beautiful sunshine. People will feel cool in the daytime. It is sunny in New York , but there’s a strong wind in the afternoon. It will be rainy in Sydney but very hot. The day after tomorrow will be sunny.

That’s the weather report for today . Thank you for listening .

早安 这是世界上一些大城市的天气报告。北京多云。天气很冷，所以出去的时候穿暖和的衣服吧。在香港有美丽的阳光。人们在白天会感到凉爽。纽约阳光明媚，但下午有大风。悉尼会下雨，但天气很热。后天将是晴天。

这是今天的天气预报。谢谢您的收听。

英语作文写作技巧：

英语考试作文试题的一个最大的特点就是时限性，即在有限的时间内（一般分配30分钟）按试题要求完成作文试题。有很多参试者最后交卷时作文题要么没有完成要么质量比较差，这其中当然有很多原因，但不可忽视的一点原因便是写作文时间不够来不及完成作文或来不及仔细思考写一篇合乎题目要求的文章。

英语作文试题一般要求字数在120字左右，段落一般为三段，因而有“三段论”一说。所谓“三段论”即全文分为三个自然段，一般结构为“首段摆事实（现象）、提观点（论点或问题），在这一部分参试者最好将题目要求中的第一个要点（一般为提出问题或观点）作为首段的内容之一；

第二段剖析现象、分析论点，这也是全文的主体部分。在这一部分参试者需要将试题要求中的所有要点的内容都加以阐述和扩展，同时注意不要信马由缰的写一些与文章主题无关的内容以免被当作跑题处理；

第三段为结论段，这一段的主要任务是为全文做一个结论性的终结，让文章显得完整和连贯。至于开头和结尾有一定的固定的套路可循。
