文章介绍了边界层风廓线仪多普勒频谱高度图的原理,并且给出了无降水、有降水、降雪、速度折叠、地物杂波、外界信号干扰等典型的多普勒频谱高度图型。研究发现,多普勒频谱高度图除了可以从中提取测风产品所需的数据外,该在线显示的图形还实时提供了许多其他潜在的气象信息,并可用于：连续监视测站上空天气;提前了解测站上空风的垂直切变;发现并确定降水起始时间;在线估测风向风速;实时判别降水云底高度和0°层的范围;验证和解释风羽剖面图产品中的奇异现象;帮助固定和移动风廓线仪选址;诊断风廓线仪系统故障;评价风廓线仪系统软/硬件性%The paper has described the principals of the stacked spectral plots （SSP）in the control and dwell display window of boundary wind profiler （BWP）. Some typical SSP patterns including precipitation, non- precipitation, snow, radial velocity ambiguity, ground clutter as well as outliers have been provided in the paper for application references. It has also been found that the raw data of BWP for producing wind measure- ment products can be obtained not only from the SSP on-lined, but also it can offer lots of potential meteorological information in a real-time. All of those said above can be used to carry out a round-clock weather monitoring over the observation station, understand the wind shear with height in advance, determine rainfall commence time and estimate the wind direction and speed, on-line estimate the bottom height of rainfall clouds and the range of 0° layer, verify the data quality in other non-real-time products, support site selection for both stationary and mobile BWP, diagnose BWP system issues, assess the software and hardware of BWP, etc. It has been pointed out for the first time that developing the potential abilities of BWP sounding in the rainfall weather systems with a high temporal resolution and making it working well in both precipitation and non-precipitation conditions are significantly meaningful with respect to BWP to be deployed to the weather observation stations nationwide in the near future to enhance the integrated capabilities in weather surveillance and detailed weather forecast. The comments and suggestions are also presented in order to improve the performance for the current commercial BWP to meet on- line analysis demand.
