多尺度大气边界层与陆面物理过程模式的研究进展
摘要
On the bases of the theories of atmospheric-boundary-layer physics, atmospheric dynamics, soil physics, fluid dynamics and biophysics, a series of atmospheric boundary layer and land surface physics process models are developed, which are applied to multiple spatial-temporal scales of earth atmospheric processes. (1) Based on land surface energy and water balance equations, the LSMPKU (Land Surface Physics Process Model of Peking University) is developed; (2) the UCMPKU (Modified Single Layer Urban Canopy Physics Process Modelof Peking University) is developed based onthe physics processesof the urban canyon canopy structures, e.g. energy balances, hydrological balances and anthropogenic heat processes; (3) the BSMPKU (Block Scale Model of Peking University) is developed with the method of (Computational Fluid Dynamics, CFD) theory. The numerical experiments showed that all the models are able to simulate the atmospheric physical process well on the certain spatial-temporal scales and had significant improvements in comparison with other similar models.
