Global Precipitation Pattern Produced by the General Circulation

• Zonal distribution of precipitation around the globe (roughly speaking)
  • 0°N - low pressure - cloudy
  • 30°N - high pressure - sunny
  • 45°N-60°N - low pressure - cloudy
  • polar latitudes - high pressure - clear
• Global Satellite images often reveal cloud patterns consistent with the above general circulation- check it out with current imagery
• Zones shift 10-15 degrees N-S annually.... Why? ANSWER
