%X In this paper, by using a two-dimensional meso-scale numerical model with the higher-order turbulent closure, the flow field structure over an isolated mountain is simulated and discussed for the period of the evening transition from valley wind circulations to mountain wind circulations. It is demonstrated that the gravity waves induced by the remained heat source play an extremely important role in the flow field evolution during the circulation transition period . And the physical figures of the corresponding turbulent structures are given at the same time .
