在中尺度数值预报模式WRF模式的基础上通过多层嵌套的方法,提高了模式的分辨率,使得最内层嵌套区域能够满足机场终端区的要求,实现了对机场终端区风场的数值模拟。选取上海浦东机场终端区做个例进行风场的数值模拟,并模拟了浦东机场发生的一次风切变天气过程,结果表明:数值模拟可以提取风切变的特征,并与风廓线雷达的结果相吻合,验证了该方法对机场终端区风场精细结构数值模拟的有效性,且数值模拟的空时分辨率均高于风廓线雷达的探测。
Based on WRF mode of mesoscale numerical prediction mode, the resolution of mode is improved by multi-level nested method so that the innermost nesting area can meet the requirements of airport terminal area, Numerical Simulation. Select the terminal area of Shanghai Pudong Airport as a case to carry on the numerical simulation of the wind field and simulate a wind shear process of the weather in Pudong airport. The results show that the numerical simulation can extract the characteristics of wind shear and is close to the wind profiler The results are in good agreement with each other to verify the effectiveness of the proposed method for the numerical simulation of the wind farm structure in the terminal area. The space-time resolution of the numerical simulation is higher than that of the wind profiler radar.
