降水条件下风廓线雷达数据质量分析及处理
QUALITY ANALYSIS AND PROCESS OF WIND PROFILER DATA ON RAIN CONDITION
摘要
Abstract
The wind profiler (WPR)can obtain the information of three-dimensional wind field effectively. However,the quality of the WPR data (especially the boundary layer WPR)will be greatly affected by rain-drops for the reasons of the detection principle of WPR.In order to improve the data reliability of the boundary layer WPR,a new screening and filling quality control method of WPR data is established by the analysis of the five beam detection or the three beam detection principle and spectral analysis of WPR FFT data.Assessment of this method is carried out by using the data of the three boundary layer WPR (Yangjiang,Chaozhou and Cong-hua).The results indicate that:(1 )Although WPR data acquisition rate is improved under rainfall condition, but the data quality of WPR is not improved together,especially under the rainstorm condition.(2)Data pro-cessing method can increase the WPR data acquisition rate,and the effect of interior site is better than coastal site.(3)Raindrops can little affect quality of WPR data below 2 km.For the data above 2 km,if raindrops on-ly cause partly missing data,then the data quality can be maintained well after processing.But if too many missing data exist,the quality of WPR data after processing cannot be insured.关键词
