1.
By use of the 1961-2005 daily mean temperature station data over China and the cumulative frequency distribution(CFD),the extremely high(low) temperature thresholds on four different time scales,day,pentad,month and season,are defined by the 90th(10th) percentiles of the CFD.
利用1961-2005年45 a中国日平均温度的站点资料和累积频率的统计方法,确定了以90%(10%)累积频率为标准的日、旬、月和季四种不同时间尺度的极端高(低)温事件的阈值。
2.
By use of the threshold value of the cumulative frequency and 10 years daily precipitation results simulated by Community Climate Model 3(CCM3),the spatial distribution characteristics of the summer extreme precipitation events are analyzed.
采用累积频率的统计方法和Community Climate Model 3(CCM3)模拟的10年逐日降水结果,分析了模拟的夏季极端降水事件的时空分布特征。
