| 摘 要： | 采用NCEP/NCAR逐日再分析资料及全国740站逐日降水资料,讨论了江淮流域持续性强降水期间西太平洋副高位置变动特征及其与非绝热加热的关系.通过个例合成研究发现:副高位置变异与强降水持续期间大气非绝热加热关系密切.强降水持续期间,副高北侧的江淮流域和西侧的孟加拉湾北部地区均存在强烈的视热源和视水汽汇.强降水发生前3 ...

| Abstract: | By using NCEP/NCAR daily reanalysis data and daily precipitation data of 740 stations in China,relationship between the position variation of the west Pacific subtropical high(WPSH) and the diabatic heating during persistent heavy rains in the Yangtze-Huaihe Rivers basin are studied.The results show that the position variation of WPSH is closely associated with the diabatic heating.There are strong apparent heating sources and moisture sinks in both the basin(to the north of WPSH) and the north of Bay of Be... |
