Case study
1, Background * The outline of hurricane Sandy
Hurricane Sandy was formed on October 22 and dissipated on October 31. Its highest winds throughout all the date was 110mph (175km/h) and the lowest pressure was 940hPa. The number of fatalities was 253 in all, and all costs of damage, at least, have risen to $65.6 billion. Affected areas by this hurricane expanded to wide range. This is Hurricane Sandy when it was near peak intensity on October 25.
Firstly what is the hurricane? It is an intense tropical depression with a very strong rainstorm. Hurricane has the other different names, typhoon and cyclone, but these don’t have any of differences in terms of their characters, and the difference is only where it takes place. A hurricane is classified to five levels according to Saffir–Simpson hurricane scale based on the maximum wind speed within one minute. According to the National Hurricane Center, its highest wind speed was 110mph, which mean Hurricane Sandy is classified to category 3. (More than Category 3 is distinguished as a record hurricane)
Due to its climate, around the Southern Atlantic, there is likely to have a hurricane between June and November (especially between Aug and Oct), and U.S, as well as the West Indies countries has been suffered from its damage. From such a historical background, these countries have a strong feeling of prevention of damage by hurricanes. Particular in U.S, when hurricane Katrina strikes U.S, the government could not take adequate measure against a hurricane, and there was a great deal of damage. Since then, such a perception has been bigger and bigger among people. After the storm became a tropical cyclone on October 22, in case of Jamaica, the government called upon the all of citizens in the whole island to take precautions against the approaching tropical cyclone.
