中文摘要: 首先对中国200个测站1951～1999年的逐日气温资料进行质量控制,剔除错误值;然后根据第95个和第5个百分位值来确定气温极端值及其阀值;最后,利用上述方法所确定的极端值分析了近50年内我国气温极端值的气候学分布特征,并结合实例分析了对极端高温和低温气候事件的检测应用。
中文关键词: 气温极端值，质量控制，百分位值
Abstract:By using daily surface air temperature data of China′s 200 stations during 1951～1999,schemes of analyzing temperature extremum are designed. Firstly, a designed quality control procedure is performed for the daily data. Next, the thresholds of extremum are estimated in terms of the 95th and the 5th percentiles. Finally, spatial distribution of temperature extrema over China for 50 years is discussed and a new technique is proposed for detecting extreme events.
