摘要
基于SWAN多普勒雷达产品和FY-2C/D卫星等综合观测资料反演产品,研制了层状云飞机人工增雨飞行航线和对流云(混合云)飞机绕云飞行航线设计方法,并分别应用于湖北省2009年2月5次层状云飞机人工增雨飞行航线设计和2010年4月12日对流云飞机人工增雨绕云航线设计模拟试验。结果表明,飞行航线设计作业区与实际作业区基本一致,设计飞行航线与实际航线也很一致;与对比区相比,催化作业效果比较明显;根据实时雷达回波按照绕云航线设计算法不断修正作业飞行航线,通过音频、图像传输与飞机上作业人员联系,可成功避开强对流云区域并达到最佳催化作业效果。
Based on Doppler radar SWAN products and retrieval products of comprehensive sounding data from FY-2C/D satellites and so on,the method designing the airplane artificial precipitation routes through stratiform cloud and around convective cloud（mixed cloud） was developed and applied to design five routes through stratiform cloud in February 2009 and a route around convective cloud（mixed cloud） in simulation test on 12 April 2010.The results show that the operating area of flight route designed agreed with the actual operating area basically,and the flight route designed was in line with the actual flight route.Compared with the contrast areas,precipitation enhancement effectiveness was much better obviously.Based on real-time radar echo and design algorithm of around cloud route the operating fight routes were modified constantly,and continuous contact was kept with the aircraft operators by audio and video transmissions,so that the strong convective cloud fields could be successfully avoided and the best results were achieved.
