英语翻译
Now satellites are helpful to forecast(预报) the weather.They are in space and they can reach any part of the world.The satellites take pictures of the atmosphere(大气) because this is where the weather forms(形成).They send these pictures to the weather station.So the scientists there can see the weather of any part of the world and tell how the weather will change.
Today,nearly five hundred weather stations in sixty countries can receive satellite pictures.When they receive the new pictures,they compare them with the earlier ones.Perhaps they may find that the clouds have changecl during the last few hours.This may mean that the weather on the ground may soon change,too.In their next weather forecast,they can tell people about it.
So the weather satellites are of a great help to the scientists at the station.In the past they could forecast the weather for about 24 0r 48 hours.Now they can make good forecasts for 3 0r 5 days.Soon,perhaps,they may be able to forecast the weather for a week or more ahead.

现在卫星对于预报天气有很大帮助.它们在宇宙之中并且能到达世界的任何地方.卫星给大气拍照,因为大气是天气形成的源头.它们将这些照片送给气象站.所以科学家们可以知道世界任何地区的气候,并且可以知道天气是怎样变化的.
现在,在60个国家的近500个气象站可以收到卫星图片.当他们收到新的图片的时候,他们可以将这些图片与先前的进行比较.大概他们可以发现云在过去几个小时的变化.这意味着地面上的天气也将要很快发生变化.在他们下一个天气预报中,他们可以将这些告诉人们.
所以气象卫星对在气象站的科学家有很大的帮助.过去,他们可以提前24或48小时内预报天气.现在他们可以在前3-5天做出良好的预测.大概不久他们就可以提前1个星期或者更多来预报天气了.
