What would happen to the circulation cells if the earth were to spin twice as fast?

Question

Based on the three cell circulation pattern

Answer 1

If the earth spins faster than the present speed,the day time(as well as night hours) will be shorter.This will create a very weaker temperature gradient(than the present one) from the equator towards the poles resulting in the weakening of the three existing cells.Consequently,the three cells may break into more cells.
