1、初二英语天气作文天气是指某一个地区距离地表较近的大气层在短时间内的具体状态。而天气现象则是指发生在大气中的各种自然现象，即某瞬时内大气中各种气象要素(如气温、气压、湿度、风、云、雾、雨、闪、雪、霜、雷、雹、霾等)空间分布的综合表现。今日我在这里给大家共享一些有关于英语天气的精选作文，供大家参考一下，盼望对大家有所关心。英语天气作文1Weather affects all of us in one way or another, directly or indirectly.For example, good weather makes people happy. Bad weather mak

4、In order to know what the weather will he, special people are hired 1oprovide this information. They collect data, analyze them and predict theweather of the coming day. This information, which is announced on the radio oron TV, is usually very accurate. Thanks to the efforts of those professionals,

5、we can always know the weather in advance and get prepared for it.英语天气作文2The weather of these days is really bad. It s foggy and there is haze inthe air. So, we can t see the things very far.

Because of the badweather, car accidents happen more frequently. I hope drivers can drive morecarefully and kee

7、p safe.英语天气作文3The weather is a set of all the phenomena in a given atmosphere at a giventime. It also includes interactions with the hydrosphere. The term usuallyrefers to the activity of these phenomena over short periods (hours or days), asopposed to the term climate, which refers to the average a

8、tmospheric conditionsover longer periods of time. When used without qualification, "weather" isunderstood to be the weather of Earth.Weather most often results from temperature differences from one place toanother. On large scales, temperature differences occur because areas closer tothe e

9、quator receive more energy per unit area from the Sun than do regionscloser to the poles. On local scales, temperature differences can occur becausedifferent surfaces (such as oceans, forests, ice sheets, or man-made objects)have differing physical characteristics such as reflectivity, roughness, or

10、moisture content.Surface temperature differences in turn cause pressure differences. A hotsurface heats the air above it and the air expands, lowering the air pressure.The resulting horizontal pressure gradient accelerates the air from high to lowpressure, creating wind, and Earth&39;s rotation then

11、 causes curvature of the flowvia the Coriolis effect. The simple systems thus formed can then displayemergent behaviour to produce more complex systems and thus other weatherphenomena. Large scale examples include the Hadley cell while a smaller scaleexample would be coastal breezes.The strong tempe

12、rature contrast between polar and tropical air gives riseto the jet stream. Most weather systems in the mid-latitudes are caused byinstabilities of the jet stream flow (see baroclinity). Weather systems in thetropics are caused by different processes, such as monsoons or organizedthunderstorm system

13、s.Because the Earth&39;s axis is tilted relative to its orbital plane, sunlightis incident at different angles at different times of the year. In June theNorthern Hemisphere is tilted towards the sun, so at any given NorthernHemisphere latitude sunlight falls more directly on that spot than in Decem

14、ber(see Effect of sun angle on climate). This effect causes seasons. Over thousandsto hundreds of thousands of years, changes in Earth&39;s orbital parameters affectthe amount and distribution of solar energy received by the Earth and influencelong-term climate (see Milankovitch cycles).On Earth, co

15、mmon weather phenomena include such things as wind, cloud,rain, snow, fog and dust storms. Less common events include natural disasterssuch as tornadoes, hurricanes and ice storms. Almost all familiar weatherphenomena occur in the troposphere (the lower part of the atmosphere). Weatherdoes occur in

16、the stratosphere and can affect weather lower down in thetroposphere, but the exact mechanisms are poorly understood.1The atmosphere is a chaotic system, so small changes to one part of thesystem can grow to have large effects on the system as a whole. This makes itdifficult to accurately predict we

17、ather more than a few days in advance, thoughweather forecasters are continually working to extend this limit through thescientific study of weather, meteorology. It is theoretically impossible to makeuseful day-to-day predictions more than about two weeks ahead, imposing an upperlimit to potential

18、for improved prediction skill.1 Chaos theory says that theslightest variation in the motion of the ground can grow with time. This idea issometimes called the butterfly effect, from the idea that the motions caused bythe flapping wings of a butterfly eventually could produce marked changes in thesta

19、te of the atmosphere. Because of this sensitivity to small changes it willnever be possible to make perfect forecasts, although there still is muchpotential for improvement.The sun and oceans can also affect the weather of land. If the sun heats upocean waters for a period of time, water can evapora

20、te. Once evaporated into theair, the moisture can spread throughout nearby land, thus making it cooler.英语天气作文4The world meteorological day is a day, the world meteorologicalorganization on March 23, time of the year. Of "the world meteorological day"every year to determine a theme, require
