Atlantic Hurricane Season

By: Ayesha Dewan

How Atlantic Hurricanes Form:

Hurricanes begin from storms coming from the western coast of Africa, when they move into the warm water of the Atlantic Ocean they create and form into tropical depressions or a tropical cyclone by the coriolis effect. (The coriolis effect is the effect of the force from a mass movement moving in a rotating system) The hurricanes get bigger and turn into tropical storms, and the hurricanes finally become severe catastrophic hurricanes.

The Bermuda High:

Bermuda High is an high area of pressure located in the Bermuda during summer and fall, that moves the storm systems westward to the atlantic. The Bermuda High is a steering mechanism moving hurricanes along the atlantic ocean, the bermuda high either moves the hurricane up the gulf coast or eastward. In the summer the Bermuda High steers tropical heat into the eastern and southern United States. The Bermuda High also shapes American weather by determining where the tropical storm goes.

El Nino:

El nino is a climate cycle located in the Pacific Ocean. El Nino involves warm water in the eastern part of the Pacific which creates a warm ocean current which later on, reduces the intensity and the size of a hurricane. El Nino reduces the size and intensity of the hurricane with the strong vertical and shear wind that moves across the atlantic basin chopping the top of the hurricane.

Water Temperature:

For Hurricanes to form over an ocean, warm water is an essential need for the hurricane to be able to form. When an hurricane encounters cold water or a cold ocean current the hurricanes intensity and size reduces and the hurricane weakens.
