Have you ever heard of satellites (卫星)? What are they used for?
Satellites are helping to forecast (预报) the weather now. They are in space, and they can reach any part of the world. The satellites take pictures of the atmosphere, where the weather forms. They send these pictures to the weather stations. So meteorologist (气象学家) can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change so that it can work better for people.
☆. Nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive the new pictures, the meteorologists compare them with the earlier ones. Perhaps they may find the clouds have changed during the last few hours. This may mean that the weather on the ground may soon change, too. In their next weather forecast, the meteorologists can say the weather will change soon.
So the weather satellites are a great help to the meteorologists. Before satellites were invented, the meteorologists could only forecast the weather for about 24 or 48 hours. Now they can make good forecasts for about two weeks. Soon they may be able to forecast the weather for more than two weeks or more ahead.
With the development of the society, weather satellites will work better and better in people's life.
