Basic Details on Hurricanes

When it comes to natural destruction of the Earth, one of the first things that may pop into your head is a hurricane (mainly because of Katrina, which devastated the north-central coast of the Northwest, primarily New Orleans). Hurricane Katrina is currently the costliest, as well as deadliest hurricane tragedy in the history of the United States. Below, you will find out information on this natural disaster maker, such as what a hurricane is and the weather conditions that causes one to develop.


What is a Hurricane?


A hurricane is considered a cyclone, but of the tropical sort, which develops as a low-pressure system in tropical sections of the world. When a cyclone hits an area, thunderstorms usually come as well. For cyclones ripping through the Northern Hemisphere, groups of winds traveling counterclockwise will appear near the surface of the Earth.


There are three different classifications of tropical cyclones to pay attention to in regards of the speed at which the wind travels. The least strong of the tropical cyclones is called a tropical depression, which is a group of clouds and thunderstorms exhibiting a distinct circulation of a surface, as well as displaying maximum wind speeds of 38 miles per hour or less. A tropical storm is a group of strong thunderstorms showcasing a “defined surface circulation,” bringing maximum wind speeds of between 39-73 miles per hour. The last category of tropical cyclones is the hurricane, which can be described as an intense tropical weather grouping bringing strong thunderstorms with a “well-defined surface circulation.” A hurricane can reach maximum wind speeds of 74 miles per hour or higher.


What Contributes to the Formation of a Hurricane?


A hurricane forms when a variety of factors are combined with one another to create a disturbance within current weather conditions. For starters, the development of a hurricane thrives off of a weather disturbance that has already existed in the area. The surrounding tropical oceans will have to reach a certain level of warmth. Moisture is also a key component for the development of a hurricane. There will also need to be the appearance of relatively light winds. If the conditions needed to create the perfect setting for a hurricane keep up long enough, the results characteristic with a hurricane will begin to show. This includes violent winds, torrential rains, large waves, as well as floods.


Statistics On the Deadliest and Costliest Hurricane in the History of the U.S.


Hurricane Katrina (which was rated a Category 5 hurricane), produced the most deaths in the history of United States hurricane fatalities, with an inconclusive number of about 1,836 lost lives. The hurricane formed on August 23rd, 2005 and dissipated on August 31st, 2005. The highest recorded level of wind speeds was 175 miles per hour, causing more than $81 million in damages in a wide-range of cities, states and countries. Although most of the media coverage paid attention to the devastation within the New Orleans area, there were other areas of the world that were also affected, such as the Bahamas, South Florida, Mississippi, Alabama, Louisiana, Florida Panhandle, Cuba, as well as the eastern part of North America.
