Not long ago after a tropical storm named Issac smashed several states in the United States, Sandy now storms again devastated many states in Uncle Sam's country. Why the United States is often hit by a storm?
Currently some areas in the United States, especially those in the east suffered damage caused by Sandy storm. Some people say that Sandy's tantrum is bigger than Katrina. However, the opinion is still refuted by some researchers.
In September, Isaac's storm also swept the coastal states of the eastern United States, particularly around Alabama. One question arises, why does the average storm more often hit the eastern part of the United States than the western region?
According to Chris W. Landsea, a researcher at the Atlantic Oceanographic and Meteorological Laboratory / Hurricane Research Division of the National Oceanic and Atmospheric Administration (NOAA), Miami, there are two reasons why hurricanes often hit the eastern region rather than the western part.
First, the water temperature in the eastern and western United States is very different. As reported by Accu Weather (27/08), along the East Coast or the eastern coast, several bays or the Gulf Stream have warm water temperatures. Water in the area has temperatures above 80 degrees Fahrenheit or about 26.5 degrees Celsius. While the water temperature in the western part is only recorded below 70 degrees Fahrenheit or below the temperature of 20 degrees Celsius.
Note the 'storm hunters', almost all storms have similar characteristics in its manufacture. A storm will form due to the presence of water at a warm temperature. A storm will not form when it is in a cold region. The second reason is due to the latitude of the tropical and sub-tropical regions.
Kerry Emanuel, Center for Meteorology and Physical Oceanography, Massachusetts Institute of Technology, explains the characteristics of storm movements. In his explanation, Emanuel said that every storm always has a similarity of movement that starts from the east and will end in the west.
This kind of movement is also called Trade Winds. The storm will continue to move westward and when it reaches its destination, the storm will slightly loosen its speed and then disappear slowly.
It does make sense that in a fairly short period of time, in the eastern United States hit by two different storms. According to the exposure in the Science Youth Dictionary, the eastern United States will always receive a storm hit when it enters August.
It is called the Hurricane Season or the hurricane season. Uncle Sam's state government clarified that the storm would be frequent from August and peaked in September.
Hurricane season will end when entering November. Until now, material losses borne by people in the eastern United States can not be counted exactly. [das]
