A Coupled Model Study on Formation and Dissipation of Advection Fog

Abstract

The effect of variations in SST on the formation and duration of advection fog event was investigated by carrying out numerical experiments for an advection fog event using a mesoscale coupled model and an uncoupled atmospheric model. Enhanced cooling of the air in the boundary layer over a cooler ocean surface increases the condensation of advected moist air and strengthens the stable stratification. Stable stratification causes a decrease in sea surface wind speed and restricts the downward mixing of drier air2
