风廓线雷达资料与NCEP再分析资料对比分析

摘要

为了对风廓线雷达探测到的水平风资料质量做一个初步的评估，本文利用NCEP再分析资料中的水平风数据分别与边界层风廓线雷达、对流层I型风廓线雷达和对流层II型风廓线雷达探测到的水平风进行对比，分析得出：风廓线雷达探测到的水平风的u、v分量与NCEP再分析资料中水平风的u、v分量的一致性较好，并且春季两种资料的一致性要优于夏季；边界层风廓线雷达在4 km以上探测资料非常少，在4 km以下资料的可信度较高；对流层风廓线雷达探测到的水平风资料在2~6 km的可信度较高。%In order to make a preliminary assessment of horizontal wind data detected by wind profiler radar. This article uses the horizontal wind data in NCEP 1o×1o reanalysis data respectively compared and analyzed the horizontal wind measured by three different types of wind profile radar. Then get the following conclusions: the u and v component of the horizontal wind detected by the wind profiler radars has a good consistency with the u and v component of the horizontal wind in NCEP reanalysis data, and the consistency of the two kinds of data in spring is better than summer;the boundary layer wind profile radar has a high reliability under 4km and the data consistency of troposphere wind profile radar is best between2~6 km.
