How and where are hurricanes are formed?

Question

just wondering cuz im a little confuse

Answer 1

Hurricanes (known as typhoons in Asia and Cyclones in the southern hemisphere) usually form in ocean temperatures of above 26.5C or 80F. They usuyally only form in areas at least 500km from the equator due to the coriolis effect which provides centripetal acceleration.

Answer 2

Hurricane are like giant engines that use warm, moist air as fuel. That is why they form only over warm ocean waters near the equator. The warm, moist air over the ocean rises upward from near the surface. Because this air moves up and away from the surface, there is less air left near the surface. Another way to say the same thing is that the warm air rises, causing an area of lower air pressure below.

Air from surrounding areas with higher air pressure pushes in to the low pressure area. Then that “new” air becomes warm and moist and rises, too. As the warm air continues to rise, the surrounding air swirls in to take its place. As the warmed, moist air rises and cools off, the water in the air forms clouds. The whole system of clouds and wind spins and grows, fed by the ocean’s heat and water evaporating from the surface.

As the storm system rotates faster and faster, an eye forms in the center. It is very calm and clear in the eye, with very low air pressure. Higher pressure air from above flows down into the eye.

When the winds in the rotating storm reach 39 mph, the storm is called a “hurricane".
