Why does a hurricane need.....?????????????????

Question

why does a hurricane need moist air, warm ocean water, converging equatorial winds, and must be at least 300 miles from the equator?
If you only know 1 or 2 things plz still answer, anything will help now.

Answer 1

A hurricane needs moist air because when the air condenses, latent heat is released. A hurricane is essentially an engine that takes heat energy and converts it into wind energy.

Hurricanes develop in areas of low pressure. In order to achieve this, warm and moist air must be concentrated in one general area. Since warm air molecules move faster and take up less area, the sea level pressure decreases.

Converging equatorial winds enhance the "spin" of the tropical cyclone. They must occur at least 3 degrees of latitude (or about 300 miles) from the equator to obtain sufficient spin because the coriolis effect increases with latitiude. At the equator, there is no coriolis force.

Answer 2

Hurricanes form and intensify over oceanic regions. They require sea-surface temperatures of at least 26°C (80°F) and the influence of the earth’s rotation to initiate a spinning circulation (Coriolis effect).

A storm surge is a rise in sea level along a coastline caused by the combination of a hurricane's surface winds and the physical geography of a coastline. Surface winds above the ocean's surface push water toward the hurricane's eye, creating a mound of water. The mound of water is then influenced by the slope of the coastline as the hurricane approaches land. If the coastline is shallow, water cannot flow away from the mound and the mound grows. If the coastline is deep, water can disperse and the mound may grow slowly or disperse depending on hurricane strength. An example of a shallow-water coastline is the Gulf Coast while an example of a deep-water coastline is found in New England.


It can be up to 600 miles across and have strong winds spiraling inward and upward at speeds of 75 to 200 mph. Each hurricane usually lasts for over a week, moving 10-20 miles per hour over the open ocean. Hurricanes gather heat and energy through contact with warm ocean waters. Evaporation from the seawater increases their power. Hurricanes rotate in a counter-clockwise direction around an "eye." The center of the storm or "eye" is the calmest part. It has only light winds and fair weather. When they come onto land, the heavy rain, strong winds and large waves can damage buildings, trees and cars.

Hurricanes only form over really warm ocean water of 80°F or warmer. The atmosphere (the air) must cool off very quickly the higher you go. Also, the wind must be blowing in the same direction and at the same speed to force air upward from the ocean surface. Winds flow outward above the storm allowing the air below to rise. Hurricanes typically form between 5 to 15 degrees latitude north and south of the equator. The Coriolis Force is needed to create the spin in the hurricane and it becomes too weak near the equator, so hurricanes can never form there.

I found a site that has pictures and explains how and what hurricanes do. I thought it would be easier to give you the site than try to explain it.

Answer 3

I think that it is because the air in the clouds is cool (witch naturally wants to settle) and the moisture from the sea is warm (and wants to rise). It Is being mixed up and around and each is trying to do what it is supposed to do. that makes the wind go faster and more warm moisture is mixed with more cool air and the wind gets faster etc. etc. etc. If it runs into cool water it will slow and stall.
