摘要多普勒雷达廓线仪被广泛用于常规的风场测量，特别是在对流层低层。同样的剖面仪，稍加修改，都是研究降水的有用工具。具体地说，剖面仪现在越来越多地被用来探索降水云系的结构，并对降水研究中使用的其他仪器进行校准和验证，包括扫描雷达以及主动和被动星载传感器。垂直定向剖面仪能够解析通过头顶的降水云系的垂直结构。标准剖面仪测量包括反射率、反射率加权的多普勒速度和光谱宽度。本文介绍了在热带降雨测量任务(TRMM)地面验证现场活动中观测到的降水云系的廓线观测。这些观测显示了在佛罗里达、巴西和夸贾莱观测到的对流系统的相似和不同之处。
Abstract Doppler radar profilers are widely used for routine measurement of wind, especially in the lower troposphere. The same profilers with minor modifications are useful tools for precipitation research. Specifically, the profilers are now increasingly being used to explore the structure of precipitating cloud systems and to provide calibration and validation of other instruments used in precipitation research, including scanning radars and active and passive satellite-borne sensors. A vertically directed profiler is capable of resolving the vertical structure of precipitating cloud systems that pass overhead. Standard profiler measurements include reflectivity, reflectivity-weighted Doppler velocity, and spectral width. This paper presents profiler observations of precipitating cloud systems observed during Tropical Rainfall Measuring Mission (TRMM) Ground Validation field campaigns. The observations show similarities and differences between convective systems observed in Florida; Brazil; and Kwajale...
