  abstract = {{O}cean mesoscale thermal feedback ({TFB}) is the influence of mesoscale sea surface temperature ({SST}) anomalies on the overlying atmosphere and its feedback to the ocean. {O}ver the past few decades, {TFB} has been shown to affect the atmosphere by inducing low-level wind and surface stress anomalies and modulating ocean-atmosphere heat fluxes ubiquitously over the global oceans. {T}hese anomalies can alter the climate variability. {H}owever, it is not clear yet to what extent heat and momentum flux anomalies modulate the mesoscale ocean activity. {H}ere, using coupled ocean- atmosphere mesoscale simulations over a realistic subtropical channel centered on the equator in which the {TFB} can be turned off by spatially smoothing the {SST} as seen by the atmosphere, we show that {TFB} can damp the mesoscale activity, with a more pronounced effect near the surface. {T}his damping appears to be sensitive to the cutoff filter used: on average, the surface mesoscale activity is attenuated by 9% when smoothing the {SST} using an ;1000-km cutoff but by only 2% when using an ;350-km cutoff. {W}e demonstrate that the mesoscale activity damping is primarily caused by a sink of available eddy potential energy that is controlled by the induced-anomalous heat fluxes, the surface stress anomalies having a negligible role. {W}hen {TFB} is neglected, the absence of sink of potential energy is partly compensated by a more negative eddy wind work. {W}e illustrate that {TFB} filtering in a coupled model must be done carefully because it can also impact the large-scale meridional {SST} gradients and subsequently the mean large-scale wind stress curl and ocean dynamics.},
