## Abstract This article investigates the linear dynamics of the sea breeze in an along‐shore thermal wind shear. The present analysis shows that the sea‐breeze circulation is tilted towards the slanted isentropes associated with the thermal wind. At a critical value of the thermal wind shear, the

Abstract
The equations of heating and motion are averaged vertically, assuming vertical distributions of velocity and temperature. A non‐linear partial differential equation of hyperbolic type is found to be satisfied by the surface velocity of the sea breeze. Numerical solutions are given for varying heating rates and for a superposed off‐shore wind. The method of integration of the equations leads to a spurious stable oscillation in the solutions and this is shown to be associated with the finite difference method used. Using dimensional analysis, a criterion for the prediction of the occurrence of sea breezes is suggested.
