| 摘 要： | 利用3830型多普勒天气雷达回波资料以及常规气象资料，研究了2002年3月20日发生在从我国西部一直延伸至黑龙江省的沙尘暴、浮尘天气过程。初步分析了沙尘暴在PPI(平面位置显示器)和RHI(距离高度显示器)上的特征，如沙尘暴的高度、厚度、浓度、移动特点、速度场分布以及垂直风速分布等特点。为多普勒天气雷达监测沙尘暴天气提供依据。 |
| 关 键 词： | 多普勒天气雷达 沙尘 反射率因子 径向速度 |

| Abstract: | A large-scale weather process of sandstorm and floating dust,which occured in the west of China and extended to Heilongjiang province on March 20 in 2002,is investigated in the article by using the 3830 Doppler weather radar data and conventional observations.The plane position indications (PPI) and range height indication (RHI) characters of the sandstorm,such as the height,thickness of echoes,the concentration and movement feature of dust,and the horizonal and vertical velocity distribution within the sandstorm,are preliminarily analyzed,thus providing a basis for the minitoring of sandstorms using Doppler weather radar. |
| Keywords: | sandstorm Doppler radar reflectivity radial velocity |
