<p>This study examines the influence of the Kuroshio intrusion into the South China Sea (SCS) on the sea surface temperature cooling (SSTC) induced by tropical cyclones (TCs) through numerical simulations. Two types of the Kuroshio intrusion are investigated, i.e. the looping path characterized by the formation of an anticyclonic eddy in the SCS, and the leaping path characterized by the minimal intrusion into the SCS. For comparison, a no-Kuroshio case with initial horizontally homogeneous stratification is also simulated. Results indicate that both the looping and leaping Kuroshio modify TC-induced SSTC compared to the no-Kuroshio case, through distinct mechanisms. The looping Kuroshio suppresses TC-induced SSTC to both sides of the Luzon Strait (LS). In the anticyclonic eddy induced by the looping Kuroshio to the west side of the LS, the suppression is related to the warmer subsurface water, smaller vertical temperature gradient and larger mixed layer depth, which lead to weaker vertical mixing. Whereas to the east side of the LS, the cause is horizontal advection. The leaping Kuroshio also suppresses TC-induced SSTC to the east side of the LS through strong horizontal advection, but it enhances the SSTC to the west side of the LS through enhanced vertical mixing. Moreover, it is found that TC-induced SSTC spreads downstream along the major axis of the leaping Kuroshio, which is caused by vertical mixing rather than horizontal advection.</p>
