摘　　要：在p坐标系中建立了100 km高度范围内自由大气风场的计算模型,根据Nimbus-7卫星探测器(SAMS)温度数据,利用热成风公式对100 km以下的风场进行了计算分析,与某火箭探空实测数据的对比曲线显示:计算风场与火箭实测风的分布规律基本一致,说明根据卫星探测温度数据,在p坐标系中利用热成风公式计算高空风场的方法是可行的。以某远程火箭为对象进行的对比计算结果表明,受高空风的影响,远程弹箭的射程差与侧偏都很大。The model of calculating wind field of free atmosphere under the height of 100 km was es- tablished according to the relationship between pressure and height in p reference frame. Meanwhile, the wind field under the height of 100 km was obtained by the geostrophic wind and thermal wind for- mulas according to the temperature data from Nimbus-7. The data comparison between the calculation and the experimental detection with long-range racket shows that the distribution law of the calculated wind field is coincident with that of the detected wind field; and the model of calculating wind field at high altitude is feasible. In order to show the effect of wind field at high altitude, a ballistic contrastive calculation of the long-range rocket was carried out. The results show that the errors of range and side deflection are obviously affected by the wind at high altitude
