As an experienced forecaster, Frank Dalton explains how scientists use balloons, satellites and computers to follow the weather. The author also goes behind the weather to explain the science of it. He shows how rainclouds form, for example, and what causes a wind to spring up. He takes us, too, inside the clouds to show the amazing cycle that rain goes through before falling to earth. And, up above the clouds, he reveals the unseen world of freezing temperatures and fierce winds that affect our daily weather. .
