摘要
观测云宏观信息及其辐射特性的工具一直都很缺乏。利用毫米波测云雷达连续观测大气中的云能够获得有重要意义的参数,这些参数包括宏观上的云厚、云高、云层数,微观上云粒子的大小、滴谱分布、冰与液态水的含量等,它们不仅决定了云的上行、下行辐射的影响效果,也是研究自然降水过程的重要参数。文章介绍了2007年中国气象科学研究院研发的应用于探测云、雾和沙尘暴垂直结构的机动式8.6 mm毫米波雷达系统（HMBQ）,重点介绍测云雷达在2008~2009年主要参加的外场试验情况,最后给出了探测得到的各种类型云（包括非降水云、弱降水云以及降雪云等）的雷达回波图,并作了初步分析。
With the recent emphasis on the understanding of the role of clouds in the global radiation budget,the scope of radar meteorology has expanded to include the measurement of cloud properties and structure.The millimeter-wavelength radar is recognized as having the potential to provide a more sensitive probe of cloud particles ranging from a few micrometers in diameter to precipitation drops.A radar operating at 35-GHz was designed and assembled primarily for observing clouds and precipitation by the State Key Laboratory of Severe Weather（LaSW） of CAMS（Chinese Academy of Meteorological Sciences） in 2006.The parameters and characteristics of the radar system as well as its activities in field experiments are introduced.Some examples of different kinds of clouds（such as Cb,Sc,Ci,Ac） are presented to demonstrate the capability of HMBQ radar.
