Ruiz Ortiz, Robin Betts, Kaitlyn Smith, Ghenet MunroeSCI 20912/02/2014University of PhoenixNatural Ocean DisasterThe word hurricane is often used for any wind that blow over 121 kilometers per hour. It is a wind of extraordinary dimensions that rotates in large circles whose diameter grows as it progresses. Hurricanes are caused by winds that blow in opposite directions. Although the majority of the times came to be highly destructive, hurricanes are an important part of the system of atmospheric circulation, which causes the movement of heat from the regions near the equator toward higher latitudes.Hurricanes form when a series of thunderstorms will accumulate and move on ocean waters warm. The warm air of the storm and the oceans surface are combined and begin to rise, so that low pressure is generated on the surface of the ocean.When traveling in opposite directions, the winds make the storm begins to rotate and lift the warm air causes the pressure decreases with increasing altitude. When the warm, humid air rises and cools, the water in the air form clouds. The entire system of clouds and air rotates and grows, powered by the heat of the ocean and the water that evaporates from the surface.When rotating the storm each time faster, form a eye or center of winds calm surrounded by a cloud band of strong winds and storms with heavy rainfall.Tropical cyclones usually weaken when touching ground, because they can no longer “feed” of the energy from the temperate oceans. However, often progressing quite inland causing much damage by wind and rain before disappearing altogether.When this phenomenon its produces on the Atlantic Ocean or the eastern Pacific, they are called hurricanes; but in the western Pacific they are known as typhoons. While to those produced in the Bay of Bengal and the Indian Ocean are called cyclones. When cyclones occur in surface in a short period of time, they become explosive cyclogenesis.
There is no two hurricanes equal, some are larger, others produce more rain, some are in the eye more grade other spiral bands have concentrated on one side only. There is also difference in intensity. TO media that the hurricane is about sea level gradually increases when the eye goes to the coast. The final level that reaches varies and depends on three factors: first the tide, the alignment between the moon and the sun plays an important role. In some places the difference between the high and low tides is very large.Second, the depth of the sea nears the coast. The deep waters imply that storm surge will not very high, to the best 4 feet instead of 10. Shallow waters could cause storm surge of up to 16 feet in height.Third, the shape of the coastline. A straight coast influences the height of the storm surge. A wave sweeping a coast of concave shape produces a much higher storm surge.The winds are the second most important effect associated with hurricanes, buildings that can withstand winds of 100 miles per hour can be destroyed by winds at 200 miles per hour, and even heavy objects can be loaded and carried as missiles. Each time you double the speed of the wind increases the destructive power four times more. The destruction of a wind of 200 is 100 times greater than that of 20 miles per hour.Another dangerous effect of hurricanes are the tornadoes, they are formed before eu a hurricane reaches Earth are not as strong or as intense as the hurricanes.Marine flooding caused by storms, are an abnormal increase in the level of the sea, associated with hurricanes and other storms maritime.Floods are generated by strong winds to the coast or by cells give intense low pressure storms and ocean.The water level is controlled by the wind, atmospheric pressure, the existing astronomical tide, staggered and the waves, the topography and bathymetry local coastal and the proximity of the storm to the coast with the greatest frequency destruction due to the flooding marine is attributable:
