Grade 5
As the amount of cloud and the way it moves change, the weather changes too. Comparing the sky in the morning with the sky in the afternoon shows clouds growing, thinning, and drifting, which tells you that weather and clouds go together. If you collect weather information such as cloud images and rainfall data for several days, you find that weather near Japan usually moves from west to east. With this rule and today's information, you can predict tomorrow's weather.
