Preliminary Analyses on Comprehensive Applications of Stacked Spectral Plots in the Control and Dwell Display Window of Wind Profilers

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 measurement 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 signifi- cantly 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.
