摘要
本文介绍了WRF中尺度模式的有关概况,分析了模式的物理结构,并利用WRF中尺度模式对河谷城市兰州冬季大气边界层的风场和温度场进行了数值模拟研究。模拟结果与观测事实基本一致,表明WRF模式具有良好的稳定性能。
The paper introduces the summary about WRF （Weather Research and Forecast） which is a middle scale model,and analyses the model＇s physical frame. Furthermore, the numerical simulation ,which is about the wind speed and temperature field in the winter atmospheric boundary layer of Lanzbou city which lies in the hollow terrain,is carried out by using WRF . The result of simulation is nearly in accordance with the observation fact. It indicates that the WRF model has favorable steadiness.
