| 摘 要： | 利用黄淮地区22个台站1956－2000年逐日降水资料，用交叉理论和EOF方法，计算并分析了黄淮地区日降水量≥25mm的极端降水特征，结果表明，黄淮地区各极值特征主要表现形式为全区一致型、南北差异型，东西差异型，黄淮地区降水极值频率及极值降水的平均持续时间都向于减少，大－暴雨的降水次数及每次降水的平均持续时间决定年降水量。

| Abstract: | The extremes characteristics of daily rainfall greater than or equal to 25mm are calculated and analyzed by cross theory and EOF method using the daily precipitation data of 22 stations in Huang-Huai area. The results show that the extreme precipitation in Huang-Huai area mainly belongs to three patterns: i.e. uniform pattern,south-north difference pattern,and east-west difference pattern.The frequency of extreme precipitation and its duration both show a decline tendency.The annual rainfall was decided by the times of rainstorm and its average duration. |
