A method of coupling the thermal and frictional forcing in the atmospheric boundary layer to a semi‐geostrophic model of the internal dynamics is developed. It is illustrated by two‐dimensional sea‐breeze simulations, which are compared with those of a two‐dimensional primitive equation model. It is demonstrated that the main features of the circulation on a horizontal scale larger than 20 km can be simulated with the semi‐geostrophic model, but the detailed local circulations cannot.
