摘　　要：静止气象卫星与极轨气象卫星的集成应用,能够充分发挥静止气象卫星与极轨气象卫星的各自优势。东亚多卫星集成降水业务系统采用拉格朗日集成算法,利用静止气象卫星的红外观测信息计算的红外冷云移动矢量,为极轨气象卫星微波降水的发展提供约束条件,实现了静止气象卫星红外观测信息与极轨气象卫星微波降水的集成,综合了两类卫星观测的优势。同时业务系统的设计考虑了多数据分级管理、多业务单元的协同工作和插件式的系统整体框架,为业务系统合理、快速处理多种来源的红外观测数据、微波降水数据,以及未来的数据更迭和算法更新提供了必要保障。The integrated application of geostationary meteorological satellite and polar orbit meteorological satellite can maximize their advantages.The East Asian multi-satellite integrated precipitation operational software follows Lagrange integration algorithm.The infrared cold cloud motion vectors calculated from geostationary meteorological satellite infrared brightness temperature provide constraints for propagating and morphing of polar orbit meteorological satellite microwave precipitation retrievals. Then the geostationary meteorological satellite infrared information is integrated with polar orbit meteorological satellite microwave information.During the software design,the overall framework of multi-data hierarchical management and plug-in multi-service unit cooperation are considered to provide the basic guarantee for operational softwares stability,fast data processing capability,future data change,and algorithm update.
