Cold air outbreak over the Kuroshio extension region

A case of cold air outbreak over the Kuroshio region is simulated over an 8 day period using a state-of-the-art coupled atmosphere-ocean forecast model that includes assimilation of observations. During the event, maximum winds reach 20 m/s in agreement with observations and the air temperature drops over 10°C, resulting in surface heat fluxes in excess of 1000 W/m
