Tropical cyclones are fueled by warm, moist air. They form over tropical oceans where the water temperature is at least 79 degrees Fahrenheit (26 degrees Celsius). The South China Sea, the Bay of Bengal, and the Gulf of Mexico all meet these criteria, which is why tropical cyclones are so common in these regions.
In addition to warm water, tropical cyclones also require low wind shear. Wind shear is the change in wind speed and direction with height. High wind shear can disrupt the formation of tropical cyclones. The South China Sea, the Bay of Bengal, and the Gulf of Mexico all have relatively low wind shear, which helps to promote the formation of tropical cyclones.
Finally, tropical cyclones require a source of moisture. The South China Sea, Bay of Bengal, and Gulf of Mexico are all located in tropical regions, which receive abundant rainfall. This moisture helps to fuel the development of tropical cyclones.
As a result of these factors, the South China Sea, the Bay of Bengal, and the Gulf of Mexico are the most active regions in the world for tropical cyclone formation. These storms can cause widespread damage and loss of life, and it is important to be prepared for them.
