摘要

Abstract

By using Gumbel distribution, pearson - IHdistribution and Weibull distribution, fitting test was conducted on highest temperature in Hebi City during 1965 -2004. The results showed Gumbel distribution is better. By using Gumbel distribution, the extreme highest temperature may be 43. 2, 43.8 ℃ in the future 50a and 80a; By using the double exponential smoothing method, it was concluded that the highest temperature annual variation in Hebi City shows decreasing trend. The highest temperature variation trend first increased then decreased a-round 1981, while the variation trend first decreased then increased around 1991. Since 1980s'the highest temperature in Hebi City increased with a fluctuation, indicating the occurrence probability of extreme high temperature events increased. Annual highest temperature peak value mainly concentrated in June and July.
