Abstract
A new numerical model has been developed to investigate the hydrological and micrometeorological phenomena near around the 3D arbitrary-shaped boundary. This model has the following features.
1) Adaptive grid method is adopted to generate the grid system. Using this method, orthogonality and density of the grid are easily and arbitrarily controlled. 2) Momentum, heat, and vapor fields are solved simultaneously. For the parameterization of turbulence, LES model is adopted. 3) Distribution of insolation on the ground surface is considered. The temperature of the ground surface is determined from the energy budget.
The flow near the isolated mountain is calculated and the results get agreement qualitatively with the experimental data.
