| 摘 要： | 通过飞机飞行起点及终点的经纬度同时利用机载GPS实时的位置参数，给出了求取飞机所在云区空气流速和流向的计算关系及计算程序。为实时跟踪催化影响区平流扩散，影响区位置控制提供了重要依据。这比用邻区定时定点探空规定层风向风速时空外推值要合理准确。给出了飞机航线的设计和云区流速和流向对PMS粒子浓度计算的影响及可能误差。

| Abstract: | In combination with airborn GPS real-time position parameter, a wind speed and direction calculating program is given with longitudinal and latitudinal starting points and destination ,thus an important base to real-time follow and the tracks of advection diffusion and position control in the seeding area is provided. It's more accurate than the way that time and space extension in the fixed-point and fixed-time wind speed and direction detected in neighbour area. In additation, the possible error in computing PMS particle concentration produced by wind speed and direction is given. |
