Hurricanes

A hurricane is a huge storm! 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 Information

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.

Hurricanes Causes

Hurricanes are tropical storms. The warm humid air of the tropics rises. As the air rises, it cools, and the moisture condenses to cloud and rain drops. Heat energy is released in the condensation process. Tropical storms usually occur in late summer and fall when the oceans in the northern hemisphere are at their warmest. When a hurricane makes landfall it loses the tropical moisture, which is the fuel that feeds the storm. Hurricanes weaken rapidly over land, due to the quick loss of water.

Hurricanes Effects

Hurricanes effects can create major problems. The maximum effects of a hurricane are usually felt within the right-front quadrant. Here the winds are usually the strongest, storm surge is highest, and the possibility of tornadoes is greatest. It is important to know whether or not your area will be affected by the right-front quadrant. It could mean the difference between maximum hurricane conditions or a glancing blow.
