摘　　要：综合应用NOAA卫星AVHRR/ 3和FY- 1极轨气象卫星高分辨 0 .5 8～ 0 . 6 8μm可见光、1. 5 8～ 1.6 4 μm近红外和 10 . 3～ 11 .3μm红外多通道资料 ,充分考虑了云的厚度、云中粒子尺度和云顶亮温的信息 ,给出了适宜飞机增雨作业云层的卫星遥感判据 ,建立了云层作业条件分析模型。实际应用表明 ,卫星遥感分析图可以有效地监测、判识和分析云层的增雨作业条件 ,应用效果好 ,可作为飞机增雨航线设计、作业决策的重要依据。通过增雨个例的微波图像特征分析 ,初步分析了AMSUUsing the visible channel (0 58-0 68 μm ), near infrared channel (1 58-1 64 μm) and infrared channel (10 3-11 3 μm) high-resolution data of polar-orbiting meteorological satellite NOAA and FY-1C and considering the cloud thickness, the particle sizes and brightness temperature of cloud top, the satellite criterions for aircraft cloud-seeding operation were given. The analysis models of cloud operating conditions were developed. The application shows that the analyzed satellite pictures can be used in monitoring and identifying the operating conditions of aircraft precipitation enhancement with the application effect being relatively good, and used as an importance basis of designing flight courses and operation decision-making for precipitation enhancement. The role and application prospects of AMSU-B microwave-channel images in precipitation enhancement were analyzed through a precipitation enhancement case.
