Sea surface temperature (SST) assimilated using an ocean circulation model is used for the atmospheric simulation of a cold-air outbreak over the Japan Sea. The upward surface-turbulent heat fluxes are significantly influenced by the high-resolution SST structure resulting from mesoscale oceanic eddies. A strong deceleration of the outbreak due to local convective activity arises in a coastal area when using the assimilated SST data, in good agreement with observations; however, this feature is not observed when using the interpolated SST. In general, the use of assimilated temperature does improve regional atmospheric simulations.
