| Abstract: | An improved three dimensional quasi static model is developed from conservation equation for momentum and mass in a terrain following coordinate system, to simulate the winter wind field and temperature field over the eastern part of the Lanzhou basin. The model needs topographic data, geostrophic departure and tethered balloon data for input data. The simplified turbulent energy equation is quoted to parameterization;the energy budget equation of the surface is used to predict surface temperature. Model results are compared to observations in December of 1996. Profiles of the model wind and temperature agree with those observed, and model meteorological field generally reflect characteristics of actual fields. Standard statistical tests of model skill showed that better effect of simulation has been acquired. |
