1961-2020年松辽流域作物生长季降水量十年际变化及其与水汽输送的关系
Decadal variations of precipitation during crop growing season and its relationship with moisture transport in the Songhua-Liaohe River Basin from 1961 to 2020
摘要
Abstract
Using CN05.1 precipitation observation data and ERA5 reanalysis data from 1961 to 2020,this study an-alyzes the interdecadal variations of precipitation during the crop growing season(May to September)in the Song-hua-Liaohe River Basin and its relationship with moisture budget,and explores the link between total moisture budget and moisture transport in the basin.The results indicate that precipitation and the moisture budget during the crop growing season of the Songhua-Liaohe River Basin exhibit similar decadal variation patterns.Five moisture channels influence precipitation in the basin,with westerlies and the East Asian summer monsoon serving as the primary moisture sources.During the 1960s to 1970s,the moisture transport in the crop growing season was prima-rily dominated by the East Asian summer monsoon.In the 1980s to 1990s,both westerlies and the summer mon-soon jointly influenced moisture transport.Since the 21st century,westerlies have become the dominant driver of moisture transport.关键词
