A tropical cyclone, also known as a hurricane, typhoon, or cyclone, is powered by warm ocean water and atmospheric conditions that allow for the formation and maintenance of thunderstorms.
Specifically, a tropical cyclone requires warm ocean water with temperatures typically above 26°C (79°F) to provide the energy needed to fuel the storm. As warm, moist air rises from the ocean's surface, it cools and forms clouds. The condensation of this water vapor releases heat, which further powers the storm and drives the winds.
In addition to warm water, a tropical cyclone also requires a low-pressure area in the atmosphere, typically caused by converging winds, to form. As the warm, moist air rises in this low-pressure zone, it cools and condenses, releasing more heat and causing the air to rise further.
Finally, the rotation of the Earth provides the cyclone with its characteristic spinning motion, which causes the winds to spiral inward toward the eye of the storm. This rotation is known as the Coriolis effect and is strongest near the equator.
All of these factors work together to power and sustain a tropical cyclone, creating a powerful and potentially destructive weather event.
Why are there less cyclone formation at the equator?
Cyclones, also known as hurricanes or typhoons, are large-scale weather systems characterized by low atmospheric pressure, strong winds, and heavy rainfall. The formation of cyclones requires a combination of several factors, including warm sea surface temperatures, high humidity, and low wind shear.

One of the main reasons why there are fewer cyclones at the equator is that the Coriolis force is weakest at the equator. The Coriolis force is an effect of the Earth's rotation that causes objects moving over the surface of the Earth to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This effect is strongest at the poles and gradually weaker towards the equator, where it becomes almost zero.The Coriolis force plays a crucial role in the formation of cyclones because it causes the air to rotate around a low-pressure center. In the Northern Hemisphere, the rotation is counterclockwise, while in the Southern Hemisphere, it is clockwise. Therefore, in the absence of the Coriolis force, cyclones would not be able to form, or they would be much weaker.Another factor that contributes to the lower frequency of cyclones at the equator is the vertical wind shear. Vertical wind shear refers to the change in wind speed and direction with altitude. Cyclones require a vertical wind shear that is relatively weak and uniform throughout the depth of the atmosphere. However, in the tropics, especially near the equator, there are large-scale circulations and convective systems that create strong vertical wind shear, which can inhibit the formation and intensification of cyclones.
In summary, the weaker Coriolis force and the stronger vertical wind shear near the equator are the main reasons why there are fewer cyclones at the equator
