关于天气的英语小作文

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

A：Nice weather ,isn't it It sure was hot last week今天天气真好上星期好热呀!

B：I'm glad it is getting cooler as we are into autumn now真高兴现在是秋天,凉快一点儿了

Today is Mid-Autumn Festival？今天是中秋节

A：What's that什么是中秋节

B：It is a traditional Chinese holidayIt falls on the 15th day of the eighth moon according to the lunar calendar是一个传统中国节日,农历的八月十五日

A：What do you do on Moon Festival ？中秋节做什么呢

B：It's a time for family reunion是全家团圆的日子

A：Oh,It's greatHow about we make a poster about Mid Autumn Festival 噢，太棒了，那我们一起做一个有关中秋的海报如何？

B：Why not Let's go and do it好啊，说干就干吧。

天气，节日，海报都有了，希望采纳哟~

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。
