摘要: 利用1960-2013年上海市徐汇站日最高气温、日最低气温和相对湿度及2004-2014年上海市10个气象站夏季日最高气温与日最低气温等观测资料,采用夏季日最高气温、高温日数、暖夜日数、高温热浪指标、炎热日数和广义极值分布等分析了上海市极端高温天气的变化特征。结果表明:1960-2013年上海市夏季日最高气温明显升高,暖夜日数和高温热浪指标明显增加,均在2013年达最大值,炎热日数和广义极值分布在1976年出现转折呈两种变化趋势。2004-2014年上海市徐汇站极端高温现象最显著,奉贤站、金山站和崇明站极端高温现象最不显著。不同极端高温指标可综合表征极端高温事件的变化趋势。

关键词: 极端高温, 变化趋势, 广义极值分布

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)
