| Abstract: | In the present paper, a two-dimensional numerical simulation is carried out to study the evolution of the elevated inversion over a narrow valley. In the simulation the spatial distribution and temporal variation of the flow , temperature and the turbulent energy fields over the valley are obtained numerically. The mechanism of the formation and dissipation of an elevated stable layer (or inversion layer ) is also discussed. The main characteritics of temperature structure simulated are in agreement with the observations. |
