Do slowly rotating or rapidly rotating planets have more
Technically, a Hadley cell is the one between
about 5 and 30 degrees latitude that transports air
southward near the surface and northward aloft. It
is one of three cells between the equator and pole.
The Hadley cell and the cell near the pole have similar
circulations. The cell in the mid-latitudes transports
air northward near the surface and southward aloft.
The Hadley cell creates the trade winds in the tropics.
On a more rapidly rotating planet than Earth (but, let's
say the same size), there may not be more Hadley cells
around the tropics, but they would be more energetic,
resulting in stronger winds and greater circulation of air.
This may cause greater convection, stronger thunderstorms,
