| 降水是全球能量/水循环中的重要过程。本文着重分析风云三号气象卫星降水探测能力,展望风云卫星后续规划中降水探测技术的发展前景。分析表明以风云三号降水星为主星,与其它风云三号极轨卫星组成的风云三号气象卫星降水探测体系,在设计层面上,从载荷类型、数量、通道设置等方面均优于目前美国第二代降水测量卫星GPM计划。风云三号降水星设计装载Ka/Ku双频降水测雷达,卫星轨道设计覆盖了南北纬50度范围内的中低纬地区,对影响我国区域的台风暴雨等强对流天气系统结构具有三维探测能力。风云三号气象卫星的降水探测能力为气象防灾减灾提供了基础支撑。 |
| 英文摘要: |
| Precipitation is an important process in the global energy / water cycle. This paper focuses on the analysis of the precipitation detection capability of FengYun-3 meteorological satellite, and looks forward to the development prospect of precipitation detection technology in the follow-up planning of Fengyun satellites. The analysis shows that the precipitation detection system of FY-3 meteorological satellite, which is composed of FY-3 precipitation satellite as the main star and other FY-3 polar orbiting satellites, is superior to the current second-generation Precipitation Measurement Satellite GPM program in terms of load type, quantity and channel setting. The FY-3 precipitation satellite is designed to be loaded with Ka / Ku dual frequency precipitation radar. The satellite orbit design covers the middle and low latitudes within 50 degrees of North-South latitude. It has three-dimensional detection ability for the structure of strong convective weather systems such as typhoon and rainstorm affecting China. The precipitation detection capability of FY-3 meteorological satellite provides basic support for meteorological disaster prevention and reduction. |
