Tyler Liebnau Mr.Virgiels Computers Tuesday, October 16, 2007 Hurricanes Hurricanes are powerful, rotating storms of tropical origin. They bring high winds, rain, and flooding. Strong winds move around a calm center called an “eye.” Every hurricane is different, but they are similar in how they are formed and how they are measured. Hurricanes can only form over oceans where the water temperature is 26.5 degrees Celsius or more. This is warm for ocean water. Hurricanes never form off the coast of New England, because the water temperature is never this warm. Hurricanes cannot form any closer than 300 miles to the equator. The earth’s rotational force is not great enough near the equator to create a hurricane’s spin. Also, the wind must be blowing in the same direction and speed from

Unformatted text preview: the ocean surface up to 29542.5 feet above sea level. Scientists use the Saffir-Simpson scale to measure hurricane strength. It has five categories that measure the wind speed and storm surge. A storm surge is a wall of wind-driven water that sweeps over the coastline when a hurricane strikes land. Category 1 hurricanes are the weakest. Maximum wind speed is no more that 91.8 miles per hour, but category 1 hurricanes can uproot trees and cause minor building damage. Category 5 hurricanes are devastating storms. Wind speeds exceed 150 miles per hour, and the storm surge is more that 18 feet. Hurricanes of this strength destroy buildings and can cause great loss of life....
