Book Description
Meteorologists today know more than ever before. They use weather maps, satelllites, ballons and planes to measure temperature, air presure, wind direction, and speed. But changes outside are not always predictable because our weather depends on the air hundreds of miles away. Sometimes meteorologists telll us to take our umbrellas when we don't need them. Other times they say we don't need a jacket when we do. Will it rain? Will it snow? Not even the experts know for sure.
Children's Literature
Weathermen sometimes slip up, as they did in March 1999 when a surprise blizzard brought snow to Washington DC, but there are many ways for them to predict storms accurately. The movement of air from one area to another causes a warm or cold weather front. Because they move fast, cold fronts produce short-lived storms followed by chillier temperatures. Warm fronts change the weather slowly and increase the heat. Meteorologists use thermometers, anemometers, and hygrometers to measure air temperature, wind, and humidity, and a barometer to record air pressure, all of which help them in their forecasting. The data are collected by the National Weather Service, weather maps are created, and information is sent to radio, television, and newspapers to prepare people for storms or sunshine, cold snaps, or heat waves. The easy-to-read text presents the facts clearly and simply. Lively, colorful, cartoon-style illustrations show the scientific concepts and instruments and ordinary people experiencing weather phenomena. The book is part of the "Let's Read-and-Find-Out Science" series.
