摘　　要：采用非静力平衡、完全可压缩的大气动力学模式,对秦山核电厂址局地风场进行了数值预报,预报结果与风场实况进行了比较分析。结果显示,从整体上看,在预报的最初6小时内,风场预报结果与地面气象测站的实况基本一致,风速比在1.5倍误差范围内的接近54%,风向偏差不超过1.5个风向角(即D≤33.75度)的可达61%。Non-hydrostatic, full compressible atmospheric dynamics model is applied to perform numerical forecast test on local wind fields at Qinshan nuclear power plant, and prognostic data are compared with observed data for wind fields. The results show that the prognostic of wind speeds is better than that of wind directions as compared with observed results.As the whole,the results of prognostic wind field are consistent with meteorological observation data,54% of wind speeds are within a factor of 1.5,about 61% of the deviation of wind direction within the 1.5 azimuth (≤33.75 degress) in the first six hours.
