What is a Huricane Essay - 1099 Words

In this paper I will talk about what is a hurricane. How they are formed. What time of the year they happen. Inform the reader on the different categories that a hurricane have. Also I will inform about the major hurricanes that happened in the United States. A hurricane or a tropical cyclone is an intense, rotating oceanic weather system that possesses maximum sustained winds exceeding 119 km/hr (74 mph). It forms and intensifies over tropical oceanic regions. Hurricanes are generally smaller than storms in mid-latitudes, typically about 500 km (311 miles) in diameter. At the ocean’s surface, the air spirals inward in a counterclockwise direction. This cyclonic circulation becomes weaker with height, eventually turning into clockwise†¦show more content†¦Warm and moist air from the ocean will begin to rise at rapid rates. As this warm air rises the water vapor condenses to form dark storm clouds and droplets of rain. Surfaces pressures begin to decrease as water vapor condenses and releases latent heat into areas where the tropical disturbance is located. (Latent heat is heat energy that is released during the phase change of water vapor.) This latent heat causes the air to become less dense. The warm air then rises; as i t rises it becomes cooler and expands. That triggers more condensation and releases more latent heat, which allows more air to rise. A chain reaction is now in place. The exchange of the heat from the surface creates a pattern of wind that moves around the center. Then converging winds—which are winds moving in different directions that run into each other—converging winds at the surface collide and then push warm air downward and the moist air upward. The rising air backs up the air that is already rising from the surface. So then, wind speeds of the storm increase. In the meantime, strong winds that are blowing at high speeds and at high altitudes help to remove the hot rising air from the storms center. But if there are wind shears; the storm will weaken. Not all hurricanes are going to be same the same when they arrive. Some will be very weak to totally destruction.

I do not think of these type of events as being evil in of themselves, but to say man has no part in them is incorrect. Who build the road and drove the car? These things occurred by the actions of man. Huricanes and earthquakes may well be part of the earth’s natural cycles and man is simply caught in them as a result of the fall.

FEMA and other federal aid were on time and effective. President Bush gave personal attention to victims. It has even been speculated that this treatment won Florida for President Bush in his re-election run. So what happened? The complete catastrophe that was Hurricane Katrina is well known by all.
