英文摘要	As two prominent natural hazards, tropical cyclone (TC) and heat compound events seem irrelevant on most occasions. TC generally leads to cooling, but could induce extreme heat days (EHD) and heat compound hazard under certain circumstances. An EHD along the southeastern coast of China (SECC) associated with Typhoon Lekima (2019) is documented with its major contributing factors. The formation and intensity of the EHD were found to be closely related to the outer circulation of Lekima by comparing a series of WRF simulations. Via a boundary layer heat budget, we found local sensible heat flux was a necessary, but not sufficient condition for this EHD. Aided by a backward trajectory analysis, we found that upstream surface sensible heat flux, subsidence induced by Typhoon Lekima, and foehn effect due to local topography played approximately equal roles to the occurrence of the EHD. The retreat of regional land-sea breeze circulation was also beneficial to the appearance of the EHD. Such TC-heat events might be more overwhelming due to more vigorous TCs with warming in the future. © 2021. American Geophysical Union. All Rights Reserved.
