| 摘 要： | 利用中国科学院兰州高原大气物理研究所平凉雷达观测基地双线偏振雷达的观测资料和地面资料，分析了雷暴云和冰雹云的ＺＨ和ＺＤＲ及其它参量的统计特征；用ＥＯＦ和相关分析方法研究了该区域的对流云和降水的日、月变化规律及地理分布，得到了这些量与地形高度及坡度的关系，揭示了六盘山对本地区云和降水影响的规律。这一工作为用双线偏振雷达研究冰雹云和下一步用区域模式研究该地区的云和降水机制提供了事实依据。

| Abstract: | Based on the radar data measured by dual linear polarization radar in Pingliang Radar Station,Lanzhou Institute of Plateau Atmospheric Physics,Chinese Academy of Sciences,we analysed the Z H and Z DR figures for thunderstorm and hail storm,studied the daily and monthly variation and spatial distribution of precipitation,thunderstorm and hail storm by EOF method,researched the relationship between these parameters and orography and effects of Liupanshan Mountain on the precipitation and cloud. This work has laid the foundation of research of cloud and precipitation by dual linear polarization radar and model simulation in the region. |
