Atmospheric Circulation and Winds

This is the large-scale movement of heat and moisture across the Earth's surface. It involves convection cells and global wind belts. This process is called atmospheric ___________.

• Conduction

• Radiation

• Reflection

• Circulation

These "local winds" bring summer thunderstorms and heavy rain to the American Desert Southwest.

• Monsoon Winds

• Sea Breezes

• Polar Easterlies

• Santa Ana Winds

These "local winds" bring cool air from over a large body of water onto the land near the coast. The cool air lowers temperatures as it replaces the rising air over the much warmer land.

• Monsoon Winds

• Sea Breezes

• Polar Easterlies

• Santa Ana Winds

These "local winds" bring hot, dry air from the Great Basin deserts up over the mountains of Southern California. These winds sweep through areas near Los Angeles and San Diego, often causing extreme wildfire conditions.

• Monsoon Winds

• Sea Breezes

• Polar Easterlies

• Santa Ana Winds

Warm, rising air in these areas creates clouds and stormy weather.  These areas occur near the equator and at 60N and S of the equator.  They are part of convection cells. 

• Low pressure zones

• Zones of conduction

• High pressure zones

• Zones of scattering
