  abstract = {{R}ecent studies suggested that tropical cyclones ({TC}s) contribute significantly to the meridional oceanic heat transport by injecting heat into the subsurface through mixing. {H}ere, we estimate the long-term oceanic impact of {TC}s by inserting realistic wind vortices along observed {TC}s tracks in a 1/2{A} degrees resolution ocean general circulation model over the 1978-2007 period. {W}arming of {TC}s' cold wakes results in a positive heat flux into the ocean (oceanic heat uptake; {OHU}) of similar to 480 {TW}, consistent with most recent estimates. {H}owever, similar to 2/5 of this {OHU} only compensates the heat extraction by the {TC}s winds during their passage. {A}nother similar to 2/5 of this {OHU} is injected in the seasonal thermocline and hence released back to the atmosphere during the following winter. {B}ecause of zonal compensations and equatorward transport, only one-tenth of the {OHU} is actually exported poleward (46 {TW}), resulting in a marginal maximum contribution of {TC}s to the poleward ocean heat transport. {O}ther usually neglected {TC}-related processes however impact the ocean mean state. {T}he residual {E}kman pumping associated with {TC}s results in a sea-level drop (rise) in the core (northern and southern flanks) of {TC}-basins that expand westward into the whole basin as a result of planetary wave propagation. {M}ore importantly, {TC}-induced mixing and air-sea fluxes cool the surface in {TC}-basins during summer, while the re-emergence of subsurface warm anomalies warms it during winter. {T}his leads to a similar to 10 % reduction of the sea surface temperature seasonal cycle within {TC}s basins, which may impact the climate system.},
