本研究提出了一种在边界层风廓线雷达连续运行的降水探测时段中对降水频谱进行在线分析的新的应用方式。详细介绍了边界层风廓线雷达在线分析原理和方法。同时结合典型降水频谱个例，分析了可获得的多个潜在的气象参数和信息。并指出，该在线分析方式的实施可以使风廓线雷达的应用领域从晴空探测向降水测量拓展；有效缓解当前风廓线雷达应用存在的瓶颈问题；间接证明边界层风廓线雷达组网间距不固定的观点。文章分析说明，随着在线分析方式的推广应用，边界层风廓线雷达将成为单站精细化气象探测和预报／服务的重要工具。%In this paper, a new application manner by on-line analyses for the stacked spectral plots （SSP） in the control ＆ dwell display window of boundary wind profiler （BWP） obtained during the rainfall time periods has been introduced. The paper has described the principle and method of BWP on-line analyses in detail, and by combined with some typical cases of precipitation SSP analyses, the evidences of potential parameters extracted from SSP have been presented. The advantages and benefits for implementation on- line analyses on SSP of precipitation, including extension application fields of BWP from clear air to rainfall weather, mitigation current BWP＇s application bottle-neck, as well as indirect verification of the stand- point for non-constant interval distance in BWP networking, have been indicated. It is believed that during the precipitation time sections BWP will be a very important tool for the weather stations to carry out de- tailed weather surveillance and forecast/service with the manner application and expansion of on-line analy- ses of BWP.
