利用NCEP(National Centers for Environmental Prediction)/NCAR(National Center for Atmospheric Research)再分析资料, 首先讨论了南亚高压在中南半岛上空建立日期的定义标准及其建立过程。结果表明, 南亚高压在中南半岛上空建立的日期平均为4月29日;合成的南亚高压建立前后的大气环流和非绝热加热的演变揭示出南亚高压建立始于菲律宾东南洋面上的反气旋环流分裂后, 西中心在中南半岛上空建立加强形成南亚高压, 该建立过程与中南半岛非绝热加热作用密切相关。在此基础上结合NOAA(National Oceanic and Atmospheric Administration)的对外长波辐射(OLR)资料分析了南亚高压在中南半岛上空的建立与亚洲夏季风建立的关系。结果表明, 中南半岛夏季风建立和南亚高压在半岛上空建立几乎同时发生;南亚高压在中南半岛建立几天后, 东孟加拉湾夏季风开始建立;南亚高压建立大约20天后, 南海和菲律宾夏季风开始建立;大约一个月后, 西孟加拉湾、印度半岛和东阿拉伯海的夏季风建立。南亚高压在中南半岛上空的建立可视为亚洲夏季风建立的开始, 其对亚洲夏季风爆发有很好的指示意义
