年际-年代际尺度上南海北部SST与东亚夏季风强度的负相关关系
The Negative Correlation between SST of the Northern South China Sea and the Strength of EASMon Inter-Annual and Inter-Decadal Time Scale
摘要
Abstract
Based on comparison of band-SST ofPoritesfrom Northern South China Sea andδ18O records from Wanxiang Cave, Gansu province andDongge Cave, Guizhou province,this paper revealed the relationship between SST of theNorthern South China Sea and strength of East Asian Summer Monsoon(EASM).On inter-annual and inter-decadal time scale, there is a negative correlation between SST of the Northern South China Sea and the strength of EASM. When SST rises, the value of stable oxygen isotope becomes heavier and the strength of EASM weakens, and vice versa. The comparison of instrument-measured SST and δ18O record from stalagmite WX42B, Wanxiang Cave verified the relationship. ENSO influences the rainfall of the monsoon region and controls the SST of the Northern South China Sea. ENSO may directly result in thenegative correlation between SST of the Northern South China Sea and the strength of EASM. But the relationship between ENSO and rainfall of the monsoon region is complicated, the relationship between SST of the Northern South China Sea and local monsoon regions still needs further study.关键词
