In a cold front, warm air slides upward over cold air at a warm front. Stratus and cirrus clouds form, the former producing gentle rain. 47 48 Atmosphere are several types of fronts. For example, stationary fronts are those in which the air masses do not move—rain, drizzle, and fog can sit over the same area for several days. Occluded fronts form when a fast-moving cold air mass traps a warm air mass against a second cold air mass and lifts it off the ground, resulting in precipitation where the air masses of different temperatures meet.

The major wind belts are located where air at the base of the convection cells moves horizontally along the ground. Where two convection cells meet, air rises or sinks, with the result that there is little wind. The passage of wind in opposite directions at the junction of two convection cells is where some of the world’s stormiest weather can be found. the behavior of liGht Sunlight is light, not heat. On a warm, sunny day, it is not sunlight that makes the air feel warm, at least not directly.

The currents continue to travel along the continent until they run into an east–west flowing current going in the opposite direction. The result is that surface currents travel in loops called gyres, which rotate clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere. The major surface ocean currents. The five gyres are the North and South Pacific, the North and South Atlantic, and the Indian. Other Factors That Shape a Region’s Climate As discussed in the San Francisco and Virginia Beach examples, ocean currents alter the temperature of the air above them.
