The eye is surrounded by the eyewall, the roughly circular ring of deep convection which is the area of highest surface winds in the tropical cyclone. The eye is composed of air that is slowly sinking and the eyewall has a net upward flow as a result of many moderate - occasionally strong - updrafts and downdrafts.
Violent windsâ¦driving rainâ¦ killer waves. These are the hallmarks of a hurricane. Also called cyclones or typhoons, hurricanes are giant storms prowling the worldâs tropical seas. An average hurricane releases as much energy in a day as the explosion of half a million small atomic bombs.Hurricanes form in the summer and fall, when the sun heats vast stretches of tropical ocean to over 82 degrees.ithin the center of the hurricane, downdrafts of dry air create a strangely calm area called the eye. fully formed, a hurricane may stretch over 500 miles in diameterâ¦ a storm nearly the size of texasâ¦ and reach a height of 9 miles. Most of these storms spin out over the open sea.
