Weather & Climate |
The wonders of weather are displayed in all their terrifying beauty in this collection of excellent programs:
Wonders of Weather
Whether warm bright morning, cold wintry day, or wet stormy night, all weather is driven by the Sun. This program shows how the sun influences our climate, and why some parts of our world are always locked in ice while others are seas of sand.
Mesmerizing time-lapse photography, archival footage of actual storms, and computer animations show how hurricanes form, how coastal cities defend themselves against storms, the path of trade winds and the Coriolis effect, jet streams and cold fronts, and polar cells and temperature zones.
Students also get to ride with real storm chasers as they speed down Tornado Alley in search of the origins of these devilish dervishes. Finishes with a look at strange things that have fallen from the sky including rain the color of blood and hail the size of golf balls. Grades 6-12. (49:18).
Raging Planet: Hurricane
Every year in the United States, hurricanes are responsible for the deaths of scores of people and cause literally billions of dollars in damage.
This program documents some of the most powerful and destructive hurricanes of all time. It uses home video, satellite images, and national and local news footage to explore the science of hurricane tracking and the advances made in forecasting where and when they will hit, show what wind tunnel experiments reveal about the awesome strength of hurricane winds, and make real the toll hurricanes inflict on people and property.
Concludes with a sobering thought: as an increasing number of people choose to live in coastal cities, it becomes more and more certain that a major hurricane disaster is in the offering. Grades 6-12. (26:52).
