近五十年云南5月降水特性分析
Analysis on Rainfall Characteristics in May of Yunnan During 1959-2012
摘要
Abstract
Based on the daily precipitation data from 36 stations ,by means of linear trend estimate and Mann‐Kendall test method ,the long‐term trends and inter‐decadal variation of precipitation ,wet days and rainfall in‐tensity in May in Yunnan nearly 54 years were analyzed .The results showed that the rainfall in large areas had no significantly increasing trend .May rainfall had obvious increasing trend in northwestern Yunnan .Rainfall in‐tensity change was the main reason in May spatial variation of rainfall ;May rainfall was slowly for increasing trend ,the increase rate of 4 mm·(10 a)‐1 ,wet days and rain intensity variation rainfall on May were an impor‐tant contribution .The Mann‐Kendall tests showed that rainfall and wet days did not happen decadal mutation , but the rain intensity had a significant decadal shifts in 1999 ,after the rain intensity was rapidly increasing .关键词
