Regionality and persistence of extreme precipitation events in China

Based on daily rainfall dataset of 542 stations in China between 1960-2003,the regionality and persistence characters of extreme precipitation(EP) are briefly studied in this paper.The results indicate that the persistence of EP in the west of Yunnan and the east of Tibet is higher,while the regionality is lower in these areas.In summer,both the two characters in the south of the Yangtze River are evidently larger,which can induce the regional floods easily.In winter,both the twa characters in the southeast coastal areas are better which might lead to regional stmng rainfall events lasting for three or more days.Both the two characters in Middle-and Low-reaches of the Yellow River are also good in autumn,so that the flood may happen quiet possibly in these areas in the season.The two characters of EP in rmst northern areas of China,except Xmjiang, are qmte poor.
