Further Studies of a Lake Breeze Part ll: Theoretical Study

Abstract

The three-dimensional structure and behavior of the lake-land breeze circulation which is induced by Lake Ontario is studied by means of a numerical model. The model is a primitive equation model which incorporates the effects of orography and the temperature prediction of the earth surface. A series of integrations is made in order to examine the effects of the large-scale prevailing flow and orography. These effects, which are found to be important in determining the structure of the lake-induced mesoscale flow pattern, are described in detail. One of the integrations corresponds to a simulation of an actually observed lake-land breeze circulation. Comparison between the simulated and the observed structures shows good agreement.
