In addition, it is the change in the air pressure that amounts to weather change. The criss-cross lines on the weather maps are Isobars. It is useful to predict weather conditions. And air pressure is measured with an instrument called, Barometer. Air is different from wind. Wind speed is measured by anemometer, an instrument with three or four metal cups revolving horizontally, (see weather news when a cyclone is approaching).
