摘要

This review article summarizes recent(2014-2019)advances in our understanding of tropical cyclogenesis,stemming from activities at the ninth International Workshop on Tropical Cyclones.Tropical cyclogenesis involves the interaction of dynamic and thermodynamic processes at multiple spatio-temporal scales.Studies have furthered our understanding of how tropical cyclogenesis may be affected by external processes,such as intraseasonal oscillations,monsoon circulations,the intertropical convergence zone,and midlatitude troughs and cutoff lows.Additionally,studies have furthered our understanding of how tropical cyclogenesis may be affected by internal processes,such as the organization of deep convection;the evolution of the"pouch"structure;the role of friction;the development of the moist,warm core;the importance of surface fluxes;and the role of the mid-level vortex.A relatively recent class of idealized,numerical simulations of tropical cyclogenesis in radiativeconvective equilibrium have highlighted the potential importance of radiative feedbacks on tropical cyclogenesis.We also offer some recommendations to the community on future directions for tropical cyclogenesis research.
