    A hurricane is defined as being a, “rotating, organized system of clouds and thunderstorms that originates over tropical or subtropical waters and has a closed low-level circulation” (“Tropical”). Hurricanes need many factors to help develop from a simple storm to a tropical storm and from a tropical storm to a hurricane. They need warm sea surface temperatures, low atmospheric winds, and a rotating area of air to form these storms (Gray, 1994). Hurricanes start when the atmospheric pressure is lower than the pressure around it. This change in pressure evaporates water from the ocean and creates the clouds and storms that we know as hurricanes (Gray, 1994).…

    For instance, the formation of a hurricane would require "very warm surface temperatures, continuous evaporation and condensation cycles, wind patterns of various directions that collide with one another, and a difference in air pressure between the surface and high altitude," ( "Hurricanes, Typhoons, and Cyclones..."). With that being said, all hurricanes are formed between the Tropic of Cancer( 23.5 degrees north latitude) and the Tropic of Capricorn (23.5 degrees south latitude) due to the warm ocean water temperatures provided in those two areas. (Ouellette 11). Furthermore, the formation of hurricanes are separated into four different distinctive stages. Hurricanes start off as a bundle of thunderstorms known as a tropical disturbances( "Hurricanes, Typhoons, and Cyclones...").…

    When the heated atmosphere air meets with the water, it increases the water temperature. “More than 90 percent of all the heat energy trapped by man-made global warming pollution goes into the ocean… the buildup of ocean heat content has increased dramatically… in the past 25 years- and it is accelerating” (Gore 56). This increase in water temperature is not good for developing storms, for it can cause them to be worse than intended.…
