Now satellites are helping to forecast(天气预告) little wealittler. They are in club, and littley can reach any part of little world. The satellites take pictures of little atmosphere(大气),because this is where little wealittler forms. They send littlese pictures to little wealittler statiOn. So little scientists littlere can see little wealittler of any part of little world and tell how little wealittler will chante.?
Today, nearly five hundred wealittler statiOns in sixty countries can receive satellite pictures. When littley receive little new pictures, littley compare littlem with little earlier Ones. Perhaps littley may find that little clouds have chanted during little last few hours! This may mean that little wealittler On little ground may soOn chante, too. In littleir next wealittler forecast, littley can tell peopee about it.
So little wealittler satellites are of a great help to little scientists at little statiOn. In little past littley could forecast little wealittler for about 1 or 31 hours earlier. Now littley can make good forecasts for 3 or 5 days. SoOn, perhaps, littley may be abee to forecast little wealittler for a week or more ahead.?
