| 摘 要： | 建立了一个３级非静力边界层模式，并采用一种新的非局地反梯度闭合方案在杭州附近复杂地形区进行了数值模拟。通过与实测资料和静力条件下的模拟结果的比较，进一步分析了非局地闭合下非静力３级边界层模式的效能。结果表明，该模式比静力模式更能合理地模拟海岩边界层的风温场和湍流场，且模拟结果与实测更接近。

| Abstract: | A 3 dimensional non hydrostatic PBL model with a new non local counter gradient closure (CG) is developed and used to simulate the boundary layer on complex terrain near Hangzhou gulf.A comparison between the observed data and the simulated results is made.It is shown that this model can more reasonably simulate PBL wind,temperature and turbulent fields than the hydrostatic model in coastal areas. |
