What are Hadley Cells?

Hadley Cells are the largest cells that extend from the equator to between 30 and 40 degrees north and south. They are also named after English meteorologist George Hadley.

What are Ferrel Cells?

Ferrel cells are the middle cells. Air converges at low altitudes to ascend along the boundaries between cool polar air and the warm subtropical air that generally occurs between 60 and 70 degrees north and south.

They are the smallest and weakest cells which extend from between 60 and 70 degrees north and south, to the poles.
