The nature of disaster is rather complicated when it is connected with elements of nature. The United States of America became a pawn of natural disasters such as hurricanes and tornadoes. The inevitable and unpredictable essence of theses phenomena leave many questions for the researchers and meteorologists. The more nature shows its “wrath”, the more it intends people to investigate the means by which it does so.
Nowadays and before many scholars and researchers get information about how to analyze hurricanes only by means of direct examples. Though, the reasons are not identified as well as the forecasting schedule of hurricanes from their primordial impulses till the very beginning of a whirlwind creation. Traditionally the US researchers gave names to different hurricanes in order to designate their individual structure and hazards as well as the anatomy of it. While analyzing any hurricane one should bare in mind that everything in the nature presupposes order. Thus, a hurricane is divided into 4 constituent parts in its anatomy:
- Outflow;
- Feeder bands;
- The eyewall;
- The eye. (Hurricane facts 2009)
Low pressure is a factor which makes water pull up and gives a way for the ominous “eye” to take over the territory within a part of ocean and shore. Here the weather mapping is an indicator which helps in designing further flow of air mass. The unstable and severe activity over the Atlantic Ocean is the major factor for hurricanes in the United States.
Among meteorologists such types of hurricane evaluation are taken into account as: physical and statistical. (Hurricane facts 2009) Many scholar draw hypothetic schemes of probable weather development over the ocean, but when the situation is straightforwardly in process and the structure of a hurricane can be designated, then comes the turn of so-called “hurricane fighters” meaning researching aircrafts with scholars and a lot of equipment aboard.
NOAA, P-3, and G-IV are the best-known aircrafts which are determined especially for analyzing hurricanes in storm and detecting their characteristic features from the inside. “The jet, which can fly high, fast and far with a range of 4,000 nautical miles and a cruising altitude of 45,000 ft., paints a detailed picture of weather systems in the upper atmosphere surrounding developing hurricanes.” (NOAA’s “Hurricane Hunter” Aircraft 2003) These aircrafts are chosen because the entire nature of a hurricane can be learnt from upside part of it. Due to GPS devices built in dropwindsondes of these machines can indicate pressure, temperature, humidity, and wind information from the inner layers of a hurricane “eye”.
The National Hurricane Center perpetually makes several observations of the oceans and work hard especially in the period from the first of June until the thirtieth oh November, when the activity of hurricanes is the most terrible and such of them like Katrina, Teresa, El Nino, Anna, Sam may plainly appear and cause human and economic destruction for the coastal objects in the Atlantic and Pacific Oceans. The aircraft data gives information not only about the current formation of a hurricane but also such “hurricane hunters” comprise the information about wind tracks of further hurricane spread.
Thus, the phenomenon of hurricane is not well learnt so far. Due to every effort of scholar to analyze and predict the emergence of a hurricane it became possible to figure out the probable development of this or that particular hurricane.
