Mm5 has a ability of simulating zwd on the whole with a bias larger than zhd ' s, which manipulates the bias of ztd simulation. the increase of mm5 resolution can improve the ability of simulating and depicting zhd, zwd and pw distribution. kf, bm and grell parametric schemes have a close ability of simulating pw at the beginning of 10 - 11h integration of mm5 model, and then the prediction bias of pw increases obviously after 20 - 21h integration
在mm5模式24h積分的前10 11h ，選用kf 、 bm和grell三種積雲參數化方案模式對可降水量的預報偏差基本接近，對可降水量具有較好的預報能力，其後三種積雲參數化方案對可降水量的預報偏差差異增大，模式積分至20 21h后對可降水量的預報能力明顯減小。 -
Grell scheme can simulate pw more accurate than others for coarse grid of mm5 and pw simulation of bm scheme is less accurate than others for fine grid of mm5. 3, the initial humidity fields reanalyzed by using gps pw can obviously improve its capability in revealing the water vapor distribution, which can result in restraining pw prediction bias during the earlier period of model integration so as to improve pw prediction
3 、用gps測量的可降水量資料調整mm5模式濕度初始場可明顯增強模式初始場描述水汽分佈的能力，使其對可降水量的描述誤差明顯減小，有利於模式初始場更好地反映出水汽分佈的局地特徵，從而有效地控制模式積分初期對可降水量的預報誤差。
