Sun, Sunlight, and Weather Patterns [electronic resource]

Climate is a changing phenomenon, the first signs of alteration appearing in its day-to-day behavior-i.e., the weather. One readily observable recent climatic change is the increase in the number and ferocity of giant weather events like hurricanes. This program explains the origin of tropical storms, tropical rainforests, and polar deserts. It shows the route and the effect of the Gulf Stream and explains its role in the Little Ice Age of the 16th century; theorizes about the events that caused the Sahara to become desert; and examines the link between these events, changes in the sun's activity, and cycles involving dust storms and volcanic eruption.

Clouds and Patterns of the Weather [electronic resource]

Whether studied from the ground, from within Earth's atmosphere, or from orbiting satellites, clouds provide useful information about emerging weather patterns. They often have a direct impact on those patterns as well. This program examines the atmospheric conditions that cause clouds to form in the troposphere and the factors that make them either retain or disperse water. Viewers learn about cloud composition and how air masses collect atmospheric moisture; how and why stratus, cumulus, and cirrus patterns occur; how cloud types are also parsed into ten groups of low-, middle- or high-altitude status; and how clouds move, change in temperature, and give way to condensation.
