Detailed explanation-1: -Tropical cyclone does not form over the equator because the Coriolis force is zero at the equator. Even though equator is a zone of wind convergence, it has nothing to do with tropical cyclone as such. Temperature is highest north and south of the equator and not exactly at the equator.
Detailed explanation-2: -The Coriolis force is important to all cyclones because all areas of low pressure must rotate to maintain their structure. Tropical cyclones draw air into the center through this rotation. This air then converges from all sides and is forced to rise, creating clouds and precipitation as the pressure drops.
Detailed explanation-3: -How do tropical cyclones form? A cluster of thunderstorms can develop over warm tropical oceans. If that cluster persists in an area of low pressure, it can start rotating. If the conditions are just right, the cluster of thunderstorms can grow in size and sustain itself and then develop into a tropical cyclone.
