     No one can change the weather. But if we read correctly the signs around us, we can tell how

the weather will be. This way of telling of what the weather will be like on the following day or two is

called weather forecasting. For many centuries and in all countries, people have studied the weather

and tried to make weather forecasting. Rings around the sun are a sigh of coming rain. Many people

feel in their bones the coming of wet weather, their joints ache. Some birds fly high if fine weather is

coming, but they fly near the ground if rainy or stormy weather is on the way. It is probably because

of the insects which they are hunting that they fly low. If you see a rainbow during rainy weather, this

is a sign that the weather will become clear and fine. Such rainbows come in the evening. If the stars

twinkle clearly at night, then fine weather will continues. If a fog appears in the morning just above a

river, then the day will be warm. If the sunset is mostly red in color, then the following day will be

warm. If a rainbow appears in the morning, rainy weather will probably come. Most of the above

saying have been made by the people who have used their eyes and brains to make weather

forecasting.
