中文摘要: 利用从全国743个站点数据集中挑选出的江南、华南地区的121个站点1961—2004年逐日日最高气温和日平均气温资料,分析了近40多年来我国南方地区最高气温的变化特征。结果表明:2003年夏季江南、华南地区出现大范围异常高温天气。虽然在1961—2004年间,江南、华南地区年平均最高气温和年平均气温均有增加趋势,但夏季极端高温事件(≥35℃日数)并没有显著增加的趋势。分析最高气温的概率分布特征,得出2003年夏季江南、华南地区出现的极端酷热天气,只是年际变化的表现,而不是长期变化趋势的反映。
中文关键词: 南方，极端高温，变化趋势
Abstract:Using the daily maximum and mean air surface temperature data of 121 stations in the area of southern China for the period 1961—2004,the change characteristics of the maximum temperature in the area was analyzed.The result is that severe heatwave with most frequent hot days occurred over southern China during summer 2003.Although there were increase trends for both the mean maximum temperature and mean temperature,it is not quite ture in the numbers of extreme hot days with daily maximum temperature above 35℃ in southern China during 1961—2004.The analysis of the probability of maximum temperature in South China during the summer of 2003 revealed that this event can't be considered as a reflection of long time trends,but rather than an episode under interannual variability.
