Analysis on Temporal and Spatial Evolution Feature of Precipitation in Liaoning Province from 1966 to 2010
摘要
Abstract
By using the precipitation data of 52 stations in Liaoning Province during 1966 to 2010,using spatial and temporal series analysis,temporal and spatial evolution feature of annual precipitation,seasonal precipitation and annual variety of different precipitation boundaries in Liaoning Province were analyzed.The results showed that in recent 45 years,the annual precipitation had a weakly decreasing trend,but the overall trend was not significant.The annual variety features of different precipitation boundaries were obvious.Through analysis,since later period of 1960s,the semi arid area of Liaoning increased,the semi humid area decreased,and the wetness area basically had no change.From the view of temporal distributions,the trends were similar in spring and winter,which were enhancive trends,but the trend in winter was very weakly.Meanwhile,the trends were similar in summer and autumn,which both showed decreasing trends.From the view of spatial distributions,seasonal precipitation showed an increasing trend from west to east,high value area of seasonal precipitation were found in the eastern part of Liaoning Province,the eastern and western precipitations in summer and winter were different.关键词
