摘要
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。
Numerical simulation of the wind field in the airport terminal area was realized. By adopting multiple layers of nested methods, the resolution of the WRF model was improved. Shanghai Pudong airport terminal area was selected to be a case for the numerical simulation of wind field, and the process of wind shear around Pudong airport was simulated. The results show that numerical simulation can extract the characteristics of wind shear according with the detection of the wind profile radar. The effectiveness of this numerical simulation method of the airport terminal area wind fine structure was validated. The space-time resolution of the numerical simulation is higher than the wind profiler radar detection.
