Abstract

Abstract: Based on daily maximum, minimum air temperature data and relative humidity data in Xuhui weather station of Shanghai from 1960 to 2013, and daily maximum, minimum air temperature data at 10 automatic weather stations of Shanghai from 2004 to 2014, trends of extreme high temperature were analyzed using daily maximum air temperature, number of high temperature day, number of warming night (WR) day, high temperature and heat wave index, number of hot day and generalized extreme value (GEV) distribution and so on.The results show that daily highest air temperature increases obviously in summer from 1960 to 2013 in Shanghai, so are the number of WR day and high temperature and heat wave index, especially in 2013.GEV distribution and the number of hot day have different trends before and after 1976.Extreme high temperature is significant in urban area of Shanghai, and not in Fengxian station, Jinshan station and Chongming station.In general, different indices of extreme high temperature can comprehensively reflect climatic change trend of extreme high temperature events.

Key words: Extreme high temperature, Variation trend, Generalized extreme value distribution (GEV)
