偏差差异 meaning in English

differences

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。
