Single-Cell Model of the General Circulation:

If you assume:

• earth is uniformly covered with water
• sun is directly over equator
• no rotation
• you will end up with a single-cell pattern -->>
  • called the Hadley Cell
  • warm air rises at the equator, cold air sinks at the poles

• This single-cell pattern is not observed.... what important process have we neglected?? ANSWER

• Now, let's assume the earth can rotate..., what happens?
