摘要
利用成都１９３３～１９９２年间的地面最低气温年极值记录，采用韦伯分布和耿贝尔分布，分别对其进行了渐近分布拟合。通过统计推断，找出了成都地面最低气温年极值所遵循的最佳渐近分布——韦伯分布。
With the data of yearly minimum surface temperature in Chengdu during the period between 1933 and 1992,the asymptotic distribution is fitted using the Weibull and Gumbel distributions and by the statistical infer method.The best distribution modelling Weibull distribution of the yearly minimum surface temperature is obtained.
