摘要：

　　The energy of tropical cyclones (TC) comes from ocean, via complex TC-ocean interaction, ocean provides enthalpy flux for TC’s development. Not only sea surface temperature (SST), subsurface ocean temperature and salinity structures (i.e. profiles), as well as TC’s attributes (e.g., size and translation speed) are all important governing factors in the TC-ocean interaction to determine the TC-Ocean coupling (cooling) effect and hence fluxes. These processes are of critical importance for TC’s LMI (Lifetime Maximum Intensity) as well as RI (Rapid Intensification). This research presents recent advancements in this field of TC-ocean interaction over the western North Pacific ocean and neighboring Seas, crossing weather and climate scales.
