Based on the daily surface air temperature data from 200 stations and daily precipitation data th from 739 stations during the second half of the 20 century , schemes for analyzing climate extremes were designed mainly according to percentiles of a non - parametric distribution and the gross errors in the daily data were removed based on a newly designed quality control procedure . the spatial and temporal characteristics of change of climate extremes over china were studied , the major conclusions are summarized as : th 1 . slight decrease trends were found for the 95 percentiles of daily maximum temperatures during summer , but larger increase trends were revealed for the 5th percentiles of daily minimum temperatures during winter , especially in northern china 本文利用中国20世纪后半叶较为完整的逐日温度和降水观测资料，设计了严格的资料质量控制方法，以统计上的边缘分布的客观定义为主要依据，确定了极端温度和降水事件,研究揭示了近50年中国极端气候事件变化的规律，得到以下主要结果： 1 .全国最高温度的极端高值略趋下降；最低温度的极端低值升温趋势显著，这种增温在冬季、在北方最显著。
