  abstract = {{A} 1/2 degrees resolution global ocean general circulation model is used to investigate the processes controlling sea surface cooling in the wake of tropical cyclones ({TC}s). {W}ind forcing related to more than 3000 {TC}s occurring during the 1978-2007 period is blended with the {CORE} {II} interannual forcing, using an idealized {TC} wind pattern with observed magnitude and track. {T}he amplitude and spatial characteristics of the {TC}-induced cooling are consistent with satellite observations, with an average cooling of similar to 1 degrees {C} that typically extends over 5 radii of maximum wind. {A} {W}ind power index ({WP}i) is used to discriminate cooling processes under {TC}s with high-energy transfer to the upper ocean (strong and/or slow cyclones) from the others (weak and/or fast cyclones). {S}urface heat fluxes contribute to similar to 50 to 80% of the cooling for weak {WP}i as well as away from the cyclone track. {W}ithin 200 km of the track, mixing-induced cooling increases linearly with {WP}i, explaining similar to 30% of the cooling for weak {WP}is and up to similar to 80% for large ones. {M}ixing-induced cooling is strongly modulated by pre-storm oceanic conditions. {F}or a given {WP}i, vertical processes can induce up to 8 times more cooling for shallow mixed layer and steep temperature stratification than for a deep mixed layer. {V}ertical mixing is the main source of rightward bias of the cold wake for weak and moderate {WP}i, but along-track advection becomes the main contributor to the asymmetry for the largest {WP}is.},
