摘要
。对近地面多个高度的ku波段雷达反射率因子Z与积雪情况下的地表降水率R进行了比较。R由雪雨强度计获得，而降水类型则由光学分差仪获得的大小和下落速度分布的CMF (Center of Mass Flux Distribution)来识别。通过与雨夹雪的比较，验证了ku波段雷达观测的雨滴常数B和β能提供雪团的特征信息。结果与x波段雷达观测结果一致。亮带在ku波段也很明显。
Z-R relationship of snow on Ku-band radar observations
. The Ku-band radar reflectivity factors Z at multiple altitudes near the ground are compared with the surface precipitation rate R in the case of snow. R is obtained by the Snow-rain intensity meter, and the types of precipitation are identified using the CMF (Center of Mass Flux Distribution) of the size and fall speed distribution obtained by the optical disdrometer. It is validated that the raindrop constants B and β with Ku-band radar observations give us the information about the characteristics of snow aggregate by comparing them with those of sleets . The results are consistent with X-band radar observations. The bright band is also noticeable in Ku-band.
