提利用1960-2013年我国南方10省（市）733个站点的日最高、最低气温和日平均气温资料，对2013年夏季我国南方高温天气的极端性进行了系统的分析。分析结果显示：2013年夏季我国南方高温天气具有显著的群发性特征，覆盖了长江中下游以及重庆等八个省、两个直辖市；也具有以高温天气过程重现构成的持续性特征，主要经历了4次高温天气过程，其中，7月22日至8月21日的第三次高温天气过程，强度最强、范围最广。重点围绕区域性高温在历史上的极端性做进一步分析，结果表明：所研究高温区域的夏季平均气温、平均最高气温、平均最低气温均破历史纪录，为近50年新高；平均高温日数和强度也超过了历年平均高温日数和强度的极值，属历史罕见；高温日数和高温强度的高值区域范围比历年向北扩展，且高值中心值超过历史最高纪录，极端性突出；2013年极端高温事件的发生次数突破了历史纪录，其中8月的极端高温事件十分突出。

Using the daily maximum,minimum and mean temperature data from 733 stations of 10 prov-inces (cities)in Southern China from 1960 to 2013,the extremely high temperature of 2013 in Southern China was deeply analyzed.The results showed that the high temperature in summer of 2013 in Southern China has significant characteristics of clustering,covering the middle and lower reaches of the Yangtze River and Chongqing areas.The high temperature has the feature of persistence,which is constituted of four high temperature processes mainly.The third time of high temperature from 22 July to 21 August is the strongest and broadest.Further analysis on the regional extreme temperatures showed that the average temperature,the average maximum temperature,and the average minimum temperature all have broken the records in the late 50 years.The time and intensity of average high temperature exceeds the extreme value in history.The extreme value scope of high temperature time and high temperature strength expand to the north,and the values of high temperature center exceed the historical records.The frequency of ex-tremely high temperature events in 2013 has broken the historical records,and is extremely outstanding in August.
