在总结前人研究成果的基础上，利用尽可能长和新的资料，进一步讨论了亚洲夏季风的爆发特征以及亚澳“陆桥”在夏季风爆发中的作用。特别是对亚洲夏季风最早爆发区进行了对比分析，并讨论了不同地区夏季风爆发的突发性和渐进性特征。此外，还研究了孟加拉湾副热带高压带分裂、中南半岛对流启动、南亚高压西行重建和初夏苏门答腊对流快速北移等亚洲夏季风爆发关键事件之间的关系。强调了中南半岛潜热加热和印度半岛感热的合理配置对副热带高压带分裂、BOB槽加深、斯里兰卡涡（北方孪生涡）激活和南海夏季风爆发的重要作用。
Based on summarizing previous achievements and using data as long and new as possible, the onset characteristics of Asian summer monsoon and the role of Asian-Australian “land bridge” in the onset of summer monsoon are further discussed. In particular, the earliest onset area of Asian summer monsoon is comparatively analyzed, and the sudden and progressive characteristics of the onset of summer monsoon in different regions are discussed. Furthermore, the relationships among such critical events during the onset of Asian summer monsoon as the splitting of subtropical high belt over the Bay of Bengal (BOB), the initiation of convection over Indo-China Peninsula, the westward advance, reestablishment of South Asian High, and the rapid northward progression of convection originated from Sumatra in early summer are studied. The important impact of the proper collocation of the latent heating over Indo-China Peninsula and the sensible heating over Indian Peninsula on the splitting of the subtropical high belt, the deepening of BOB trough, the activating of Sri Lanka vortex (twin vortexes in the Northern and Southern Hemispheres), and the subsequent onset of South China Sea summer monsoon are emphasized.
