Category 1 hurricanes are considered the least destructive on the scale. In appearance, a tropical cyclone is like a huge whirlpool - a gigantic mass of revolving moist air. These global projections are similar to the consensus findings from a review of earlier studies in the 2010 WMO assessment. Institutional capacity and economic development are believed to play protective roles, but previous efforts have been unable to disentangle their relative effects. A stochastic model for generating long-term annual extreme winds, on the basis of short-term records, is investigated in order to utilize limited lengths of wind records for obtaining extreme wind speeds in a tropical cyclone-prone region for structural design.
