prediction bias meaning in Chinese
预测偏倚
Examples
- 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积分的前10 11h ,选用kf 、 bm和grell三种积云参数化方案模式对可降水量的预报偏差基本接近,对可降水量具有较好的预报能力,其后三种积云参数化方案对可降水量的预报偏差差异增大,模式积分至20 21h后对可降水量的预报能力明显减小。 - 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测量的可降水量资料调整mm5模式湿度初始场可明显增强模式初始场描述水汽分布的能力,使其对可降水量的描述误差明显减小,有利于模式初始场更好地反映出水汽分布的局地特征,从而有效地控制模式积分初期对可降水量的预报误差。
