| Abstract: | The Weibull, the Bumbel, the Pearson III and the logarithmic normal distribution functions are used to fit the asymptotic distribution of the yearly maximum surface wind speed over Chengdu between 1933 and 1997. The result shows that the Gumbel and the logarithmic normal distribution are better ones. |
