报告摘要：The western North Pacific is characterized by the most active monsoonal circulation and the most frequent tropical cyclone (TC) formation among all of the basins. Other than the large-scale monsoonal circulation which can provide favorable environmental conditions for tropical cyclogeneses, the interaction of convectively-coupled multiscale waves can help evolve incipient disturbances to tropical cyclones. From the aspect of climatological statistics, the modulation of high-low-frequency waves on tropical cyclogeneses was investigated extensively in previous studies. However, there is still lack of deep understanding on the evolution process from tropical disturbances to tropical cyclones in association with the interaction of multiscale monsoonal systems. Based on diagnostics analysis, dynamic theory and numerical simulation, the optimum configures of monsoonal circulation types and multiscale waves during the period of TC formation are examined, and the key physical factors controlling TC formation are explored, which can be instrumental to reveal the roles of the multiscale waves in tropical cyclogeneses. The studies can not only advance the understanding of the mechanism of TC formation, but also provide a practical guide for the prediction of tropical cyclogenses.
