What is the general pattern of winds near the equator?

• The equator is a region of mostly high air pressure due to cooler, denser air.

• The equator is a region of mostly low air pressure due to warmer, less dense air.

• The equator is a region where low- and high-air-pressure atmospheric bands come together to create warm, weak air patterns.

• The equator is a region where high- and low-air-pressure atmospheric bands come together to result in cool, strong air patterns.

Santa Ana winds form around the Great Basin and blow at high speeds into Southern California. These winds can damage trees and buildings and can increase the danger of wildfires.

• Air moves from an area of high pressure to an area of low pressure.

• Narrow valleys and canyons slow the movement of wind as it enters California.

• Cold, dry air flows down from higher elevations following the shape of the land.

• Warm, dry air from the Pacific Ocean flows over Southern California, igniting fires.

• The air changes in speed, pressure, and water content as it moves into California.
