Introduction

With reference to contrasting examples examine the ways in which the impact of tropical cyclones vary. Tropical cyclones are systems of intense low pressure. They are known for they're extreme velocity winds and their heavy torrential rainfall. Tropical cyclones tend to develop over warm seas (especially tropical where there is enough depth of warm water) in autumn when sea temperatures are the highest and they form in the trade wind belt where the surface winds warm as they blow towards the Equator. Tropical cyclones are known by different names depending on where in the world they form; hurricanes, typhoons and cyclones. Once formed they move westwards . They are another mechanism by which surplus energy is transferred away from the tropics. Tropical cyclones have caused widespread destruction and deaths. Hurricanes are the tropical cyclones of the Atlantic. In mid August 1992 hurricane Andrew formed in the middle of the Atlantic Ocean. ...read more.

Middle

It also created 30 years worth of debris. Although the area was declared a national disaster area later, first aid efforts were delayed by the confusion and by the bureaucratic problems of moving soldiers and trucks which were moved only when the area was declared a national disaster area. Being the costliest disaster in American history it even raised the problem oh insurance claims. Insurance companies were left with 100's of thousands insurance claims which meant a loss amounting to 18 billion dollars. Many insurance companies were pushed out of business while others had to put a limit on future policies. Following Hurricane Andrew, many companies have cancelled or limited property insurance in coastal areas of Florida. Thousands of property owners and businesses were left without cover. The hurricane's powerful winds showed the poor building policing and construction work. Concrete block construction resisted much better than buildings with timber frames and this influenced people's future house purchasing. ...read more.

Conclusion

Very few people had insurance and consequently 500,000 people were left homeless. Crops were completely destroyed and 2000 cattle were lost. On a whole the impact of tropical cyclones vary on the speed of population evacuations and the degree of preparedness of the authorities and the population. In LEDC countries like Bangladesh there is not a great system of preparedness and people were not informed in time. The deaths were caused by the spreading of disease and the low quality of the infrastructures which quickly collapsed under the force of the tropical cyclone. In the United States instead we see that the population was informed on time and that the evacuation plans took place and there was a low number of deaths. Help was not immediately available but on the long term the help was given and the population recovered quickly, Some infrastructures such as buildings poorly built served to understand how future buildings would have to be constructed and so to minimise the risk of death and destruction. ...read more.
