Affect that Atlantic Ocean Temperatures May Have On Hurricanes

Introduction

The year 2010 is considered as an active years for natural disasters which hit almost quarter part of the earth living being and destroyed millions of life. Asia, Australia and United States are considered according to one report of global climate association is the severe weather countries which are devastated by spawned tornadoes, destructive hail and damaging winds. United States was reported as less affected by the hurricanes even though the Atlantic Hurricane Season made around second most number of hurricanes in the last 25 years. Despite the continuous activeness of Atlantic Hurricane Season, global cyclones tropical development remained below the average for fifth consecutive year. United State is reported as the most losses insured for the year 2010 mainly due to winter damaging and springtime weather. Among the ten top insured natural catastrophic events in 2010, five were considered as the severe events which devastated by means of tornadoes and thunderstorm wind. Hurricane are termed as the most devastating natural disaster emerge from the ocean which occur from the collision of different waves and overlying temperature of the sea surfaces. Regular of ten tropical storms increase each year in the Atlantic Ocean due to temperature changes.

Discussion

Hurricanes are uncommon weather phenomena. Technically, a hurricane is a tropical cyclone originating in the Atlantic Ocean, eastern Pacific Ocean, or the Gulf of Mexico. In the western Pacific Ocean and the Indian Ocean, this weather phenomenon is known as a typhoon. For much of the year, large portions of the tropical oceans present with the potential to develop hurricanes. This potential is a result of thermodynamic disequilibrium between the atmosphere and the underlying ocean. Both the ocean and the atmosphere are typically at or near the same temperature; however, the exchange of entropy from the ocean to the atmosphere drives this thermodynamic disequilibrium. Hurricane do not arise spontaneously even under favorable conditions, and relatively few hurricanes develop in the world each year. (Manzello, pp. 5-39)

To initiate the development of a hurricane a strong atmospheric starting disturbance is required. For the North American continent, this starting disturbance is provided by a macro scale wave that arises from the instabilities of the east-to-west atmospheric flow over sub-Saharan Africa during the northern latitude summer. These atmospheric waves are a result of a heat-induced region of low pressure over the sub Saharan Africa, which is moving westerly; it then collides with a region of moist air off the west coast of Africa. Similar waves can form over Central America and the Gulf of Mexico, known as tropical waves of unstable air frequently run as far west as Florida without developing into hurricanes. Often, in a single hurricane season, 50 to 60 such tropical waves emanate from West Africa. (Manzello, pp. 5-39)

What causes one tropical wavy to develop into a hurricane whereas another tropical wave does not is an area of intense research. What is known is that a number of empirical conditions are necessary for hurricane formation. One of the ...
