North America has some of the most varied and dynamic weather on the planet. Every year, the Gulf Coast is battered by hurricanes, the Great Plains are ravaged by tornados, the Midwest is pummeled by blizzards, and the temperature in the Southwest reaches a sweltering 120 degrees. Extreme weather can be a matter of life and death, but even when it is pleasant--72 degrees and sunny--weather is still central to the lives of all Americans. Yet few of us really understand the science behind weather.This DVD companion to The AMS Weather Book--the most comprehensive and up-to-date guide to our weather and our atmosphere--provides over one hundred graphic illustrations in full color and exceptional detail that serve to illuminate and explain the full host of atmospheric phenomena, from the Northern Lights and lake effect snow to the jet stream and ocean currents. All of the concepts illustrated on this DVD relate to people's every day lives and can be used in the classroom to complement the book, or as educational tools in their own right.
