When there is cooperation from both the ocean and atmosphere, a hurricane is formed. The first element necessary is the water temperature which needs to be at least 26.5 degrees Celsius.
Heat is essentially the source of energy.
Hurricanes will weaken when they travel over land or cooler waters. This is due to the lack of heat and moisture. Next, the relative humidity has to be high. The concentration of latent heat is critical to driving the system. Next, vertical wind shear is important.
