2019中考英语：the weather satellites_气象卫星

No satellites are helping to forecast(预报) the eather. They are in space, and they can reach any part of the orld. The satellites take pictures of the atmosphere (大气), because this is here the eather forms (形成). They send these pictures to the eather stations. So teorologists(气象学家) can see the eather of any part of the orld. From the pictures, the scientists can often say ho the eather ill change.

Today, nearly five hundred eather stations in sixty untries receive satellite pictures. When they receive ne pictures, the teorologists pare them ith earlier ones. Perhaps they may find that the clouds have changed during the last fe hours. This may an that the eather on the ground may soon change, too. In their next eather forecast, the teorologists can say this.

So the eather satellites are a great help to the teorologists. Before satellites ere invented, the scientists uld forecast the eather for about 24or 48 hours. No they can make good forecasts for three or five days. Soon, perhaps, they may be able to forecast the eather for a eek or more ahead (提前).
