The equator has very little wind, which causes rain-filled clouds to remain still for longer periods of time

The equator has stronger winds that cause clouds filled with precipitation to burst, resulting in precipitation

At the equator, warmer conditions create an increase in evaporation.  Evaporation leads to more precipitation.

At the equator, warmer conditions create a decrease in evaporation.  Less evaporation leads to more precipitation.
