Long-term trend analysis of precipitation,temperature and extreme weather in Kunming
摘要
Abstract
Based on the daily temperature and precipitation data of Kunming meteorological station in 1951‐2013 ,the author used methods of linear trend ,Sen slope estimation ,Mann‐Kendall methods to analyze the characteristics and trends of precipitation , temperature and extreme weather in Kunming .The results showed that ,from 1951 to 2013 ,the average temperature mutation took place in 1994 ;Annual average temperature and the temperature of the four seasons showed a tendency of warming .Be‐sides ,it showed a decreasing trend in annual precipitation ,summer rainfall and autumn rainfall ,while spring rainfall and winter rainfall showed an upward trend ,but the trend was not significant ;In the extreme precipitation index ,Consecutive wet days showed a downward trend ,consecutive dry days and maximum 1‐day precipitation amount had a upward trend ,but the trend was not significant .In the extreme temperature index ,Warm spell duration indicator ,Warm nights and Warm days increased significantly ,while cold spell duration indicator ,cool nights and cool days reduced significantly .关键词
