HURRICANES IN THE UNITED STATES AND OTHER GEOGRAPHICAL AREAS - Research Paper Example Hurricanes are one of the most devastating natural phenomena known to man. They are chactacterised by strong winds, storm surges, and heavy rainfalls, all of which when combined, leads to extensive loss of human life, destruction of property and ecosystems and the alteration of landscapes. Definition of hurricanes and an exploration of their formation process A hurricane is a spiralling and powerful form of a tropical cyclone, which originates from warm sea surface and then moves towards the mainland. In order for hurricanes to be formed, the sea water must have surface warmth of more than 27 degrees. This temperature level results in the release of moisture and heat into the atmosphere. As the sea moisture rises it condenses to form storm clouds. During condensation, heat (latent heat of condensation) is released into the atmosphere. It is this heat which propels the hurricane. The latent heat makes the atmospheric air warm thereby causing the air to rise further. The void left by the risen air becomes occupied by additional moist air from the surface of the ocean in a continuous, cyclical pattern. This results in the formation of a wind pattern which is circular in nature. This is what is known as a hurricane. Provided that a hurricane remains above a sea surface of 27 degrees and higher, it keeps on pulling moisture from the sea, there by becoming larger in size and in momentum. Propelled by the latent heat and wind patterns in the sea, the hurricane may then head towards land where it finally loses its momentum.
