Cyclones develop when warm, moist air rises from the ocean surface, creating a low-pressure area. As the air rises, it cools and condenses, releasing heat and fueling the storm. The Earth's rotation causes the storm to spin, forming the characteristic circular shape. Favorable conditions such as warm sea temperatures, high humidity, and low wind shear are essential for cyclone formation. In India, the Bay of Bengal is particularly prone to cyclones due to its warm waters and geographical features.
