If there's one thing that many of us find ourselves talking about, it's the weather. Such discussions, however, usually involve general observations, not data-based information derived from the instruments that actually measure such variables as air pressure, humidity, or wind strength. In this concise and compelling volume, young readers will be treated to clear information and useful illustrations that will help them gain a true understanding of what's behind all the talk about weather. In fact, this accessible book provides tips so that would-be meteorologists can take a hands-on approach to measuring rainfall, wind direction, humidity, and more.
