Abstract
Current events often deal about natural disasters. Worldwide, many natural catastrophes happen every year: tornadoes, thunderstorms, floods, hail, drought, fire, seism, volcano activity. Theirs effects often are dramatic. Lately, we heard about the tsunami in Asia, and also about the seism in Pakistan. These phenomena were murderous. A hurricane is one of the most spectacular and powerful of weather systems. As is shown in the histogram at the top, a windstorm is also one of the most frequent of natural disasters, with 121 occurrences in 2004. First, I will introduce the different terms for hurricanes and theirs categories. Then, I will explain when, and where, hurricanes form. Besides, I will explain the formation and the structure of a hurricane. At last, I will quote the effects. hurricanes are classified by form and intensity. A tropical depression is constituted of clouds and thunderstorms with surface winds of less than 63 kilometers per hour.
