Hurricanes occur all over the world, at different times, but commonly through June first and late November. However in late August 2005 a catastrophic hurricane struck. This was Hurricane Katrina. With winds traveling over one hundred miles per hour making it a category five on the Saffir- Simpson Hurricane Scale it was said to have cause billions of dollars’ worth of damage. Hurricane Katrina flooded nearly forty thousand homes, and killed at least two thousand people (“Hurricane”). An average category five hurricane has enough energy to power street lamps for more than twenty seven thousand hours (Williams 58). Knowing about Hurricane Katrina, and the devastation of the city in New Orleans would be beneficial. Also, general information on hurricanes can help civilians and people of higher authority better understand and prepare for damage that could once hit their town and community. Because experts know the general information on these storms they can help explain to the public why and how Hurricane Katrina and other hurricanes occur. Hopefully, in the future civilians will know and use this information to their advantage against hurricanes.
A hurricane is a type of natural disaster that can be harmful and destructive to anything in its way. Every year five to six hurricanes are formed, damaging and destroying people’s homes, landmarks, and anything in its path (“Hurricane”). Before a hurricane is developed it is known as a tropical storm. To be a tropical storm wind speed must be at least thirty eight miles per hour (“Hurricane”). Once wind speeds reaches seventy four miles an hour it can then be classified as hurricane (“Hurricane”). Large scale storms, like hurricanes have a variety of ways to measure the severity. For example, many hurricane experts use the Saffir- Simpson Hurricane Scale to distinguish what category it is (Torres 8). At the top of the scale is a category one, wind speeds must be between seventy four and ninety five miles per hour. The damage of a category one hurricane would be minimal. Next category two hurricanes commonly have moderate damage with wind speeds traveling anywhere from ninety six through one hundred and ten. For a hurricane to be entitled a category three hurricane wind speeds must range from one hundred eleven through one hundred thirty miles per hour. Category three hurricanes will cause extensive damage to anything it hits. Fourth, is a category four hurricane, it will cause extreme damage and wind speeds must travel between one hundred thirty one miles per hour and one hundred fifty five. And lastly the most severe of them all is a category five hurricane. With catastrophic damage and wind speeds over one hundred and fifty five miles per hour this category hurricane will leave nothing in its path. First, before storms can be given the name of a hurricane gigantic heat pumps must gather energy from the sun (Williams 16). Once...
