Abstract: According to statistic infer method,the asymptotic distributions,Weibull distribution or Gumbel distribution,for yearly extremes of surface temperature and surface wind in China were discovered.In this study we used the data of 173 stations for yearly maximum surface temperature and 158 siations for yearly minimum surface temperature and 83 stations for yearly maximum surface wind during the periods from 1951 to 1982.Finaly,in this paper,the characteristics of the asymptotic distributions were discussed briefly,
