高分辨区域面雨量自动监测系统应用探讨

Application of Surface Rainfall Automatic Monitoring System in High Resolution Area

随着雷达技术的发展,X波段雷达在区域面雨量监测中开展试验、运用。分析雷达自动监测面雨量系统研究进展,阐述在云南省大理进行的中国第1套高分辨区域面雨量自动监测系统的建设情况,监测系统由X波段测雨雷达、4套雨滴普仪和2组90m×90m的翻斗雨量计组成,通过现场应用对比分析,得出监测数据是可靠的,可逐渐在山洪易发区与小流域、大城市与较大流域等推广应用。

With the development of radar technology, X-band radar is carried out testing and using in regional surface rainfall monitoring. The article analyses research progress of radar automatic monitoring surface rainfall system and expounds the construction situation of China＇ s first surface rainfall automatic monitoring system in high resolution area which is builded in Dali, Yunnan. The monitoring system is composed by precipitation-measuring radar in X-band, four sets of disdrometer, two groups of 90 m× 90 m＇ s tipping bucket rain gauge. Through application contrast analysis at spot, it is found that the monitoring data is reliable and can be popularization and application gradually in flash flood areas, small watershed, large city and basin.
