HURRICANE ANOMALY2Hurricane AnomalyOne of the Earth’s most lethal and disruptive storms are hurricanes. A hurricane is an aggressively powerful swirling tropical storm that can be anywhere from 200 to 2,000 kilometerswide. Hurricanes have a calm center, also known as the eye, where low pressure can be measuredanywhere from 20 and 100 kilometers wide. These storms happen in mostly tropical areas aroundthe world and are actually called typhoons in Asia and the Pacific and called cyclones in the Indian Ocean region and in Australia. Over the lifespan of a hurricane they can discharge as much power as a nuclear bomb (National Hurricane Center, n.d.). These storms seem to be increasing in nature as populations flourish around coastal regions and the destruction from thesestorms are continually increasing in size and power.FormationHurricanes are located in the Atlantic and Pacific oceans, which are swirling tropical storms. The Northern Indian Ocean or the Bay of Bengal would normally consider these storms acyclone whereas storms in the Pacific Ocean are usually called typhoons (National Geographic, 2017). Also, the roots of how the hurricane got the name hurricane was “centuries ago, the Spanish used Huracan, an indigenous word for evil spirits and weather gods, to name the storms that sank their ships in the Caribbean” (National Geographic, 2017, para. 3). Regardless of what they are called they are known to be lethal to those living on the coasts. These tropical storms areformed in oceans with warmer water of around 80 degrees and higher and can usually begin as a heavy rain or a tropical event. To start, warmer water nourishes lower pressure storms until winds stretch upwards in speeds of over 38 miles per hour and at that point the storm then becomes a tropical cyclone or what some would call a tropical depression. These have at the very least one closed isobar and

According to the WW2010 Department of Atmospheric Sciences (DAS) (2010), a tropical storm looks like there could be hurricanes in the area but it is only due to the increased circulation of winds. The DAS also explains that the location of the heaviest rainfalls develops near the fundamental core as spiraling rain bands spin throughout the eye of the storm. The walls of the eye are also where the most precipitation and the fiercest winds are connected while the center is usually calm with little precipitation.
