4. 3. This action creates a low pressure area which draws in air masses from cooler areas. 1. During the spring and summer, the sun heats the land from direct sun’s rays. 2. Air above the land is warmed, causing it to rise. 4. A current of moist air begins to flow in from the ocean. 5. As the moist air rises, it cools, causing heavy rains south of the mountains.

6. 1.During the winter, the cold interior is not influenced by warm ocean currents. 2.This cool air descends, causing a high pressure area. 3. Cool, dry winds move out toward the ocean. Winds reverse ( low pressure is now found over the southern hemisphere.) LAND OCEAN
