【正文】 legram wanted to go back to his hotel in a taxi (D)Now satellites are helping to forecast the weather. They are in space, and they can reach any part of the world. The satellites take pictures of the atmosphere(大氣)，because this is where the weather forms. They send these pictures to the weather stations. So meteorologists(氣象學(xué)家)can see the weather of any part of the world. From the pictures,the scientists can often tell how the weather will change.Today,nearly five hundred weather stations in sixty countries receive satellites pictures. When they receive new pictures, the meteorologists pare them with earlier ones. Perhaps they may find that the clouds have charged during the past few hours. This may mean that the weather on the global surface may soon change too. I n their next weather forecast, the meteorologists can tell this.So the weather satellites are of great help to the meteorologists.
