DENDROLOGY

Detailed explanation-1: -Only tropical cyclones that form over the Atlantic Ocean or eastern Pacific Ocean are called “hurricanes.” Whatever they are called, tropical cyclones all form the same way. Tropical cyclones are like giant engines that use warm, moist air as fuel. That is why they form only over warm ocean waters near the equator.

Detailed explanation-2: -Globally, about 80 tropical cyclones occur annually, one-third of which achieve hurricane status. The most active area is the western Pacific Ocean, which contains a wide expanse of warm ocean water.

Detailed explanation-3: -Tropical cyclones form over oceans of the World except in the South Atlantic ocean and in the South eastern Pacific. During the Southern Hemisphere Summer, the intertropical front in these areas moves only a degree or so south of the equator which is not far enough for the coriolis force to become effective.

Detailed explanation-4: -The formation of a hurricane is complicated, but basically, it depends on three factors. First, you need warm water, at least 80 degrees. The second ingredient is moist air. And finally, there needs to be converging winds for a hurricane to form.
