地形对近地层风场日变化影响的数值模拟

利用修改的Mass模式和辽宁地区的地形资料，模拟了地形加热作用对辽宁地区近地层风场日变化的影响。结果表明，渤海和黄海北部海域对辽宁地区近地层风场的影响起着非常重要的作用。由于海陆加热的不同，加热冷却速度的不同以及山地地形等可产生不同的流场日变化。

Numerical Simulation of Terrain Effect on Diurnal Variation of Wind Field in Ground Layer

Using the modified MASS model and terrain data of Liaoning, the effect of terrain on diurnal variation of the wind field in the ground layer is simulated. The result shows that the Bohai Sea and the northern Yellow Sea have significant effect on the diurnal variation of the wind field in the ground layer in Liaoning Province, and that differences in heating rate and terrain may result in the diurnal variation of the wind field in the ground layer.
