中文摘要: 利用北京风廓线雷达五波束探测中的垂直波束资料,进行了垂直速度在预报中的应用研究。通过对垂直速度的分级显示,配合地面气象记录,对不同的天气个例进行分析,结果表明:平稳晴空的天气风廓线雷达所测量的垂直速度很小,基本上在±1 m·s-1范围内;而有降水时,风廓线雷达所测得边界层的垂直速度基本上都是朝向地面的,不同相态降水粒子的垂直下落速度有明显的差别。分析表明风廓线雷达垂直速度的探测对研究晴空大气的垂直运动、判断降水粒子相态和降水预报有应用价值。
Abstract:Applications of vertical velocity in forecast are studied by analyzing the vertical beam data of Beijing wind profiler radar (WPR) data. The different weather cases are analyzed via vertical velocity classification display and surface meteorological records. The results show that the vertical velocity measured by WPR is small in clear sky between ±1 m·s-1. But in precipitation days, boundary vertical velocity is mainly toward to the ground with different speeds between precipitations in different phases. The results indicate that vertical velocity probed by WPR has application values in researching vertical velocity in clear sky, judging the precipitation phases and forecasting precipitation.
