Why do Tropical Cyclones occur?
Tropical Cyclones occur over warm and tropical oceans/seas because of warm and moist air that is trying to escape into the atmosphere. This creates a low pressure system, where the water and air meet. The hot rising air creates dense, rainy clouds around the air that is trying to escape the low pressure system in the eye of the cyclone.
