Detection Analysis and Efficiency of New Generation of Weather Radar over High Mountains

摘要

Based on years of use experience of previous 713 weather radar in Mount Tai, the optimal detection elevation and minimum detection height of the new generation of weather radar CINRAD/CD in Mount Tai were calculated and analyzed. According to the comparative analysis of maximum reflectance factor (DBZM) and vertical integrated liquid water based on cells (C-VIL) of the new generation of weather radar in Mount Tai (CD radar in Mount Tai) and Jinan (SA radar in Jinan), differences of echoes observed by the radar at the same elevation at different altitudes were revealed. It is pointed out that the ability of CD radar in Mount Tai to detect precipitation echoes was inadequate because the radar used the same elevation of above 0.5° as the radar in the plain. Moreover, some suggestions were put forward to improve the efficiency of CD radar in Mount Tai.
