摘要
沙尘天气是一种特殊的天气现象。为了研究沙尘天气下气溶胶的特性,利用激光雷达和粒子计数器的实际测量结果,对浮尘、扬沙和沙尘暴三种天气下沙尘气溶胶谱分布特性进行了分析,并分析了风的扬沙作用.最后利用激光雷达测量结果对扬沙天气的形成发展和消退过程进行了分析.
The size distribution and extinction characteristics of sand particles are investigated for three representative sand weathers, light dust, sand blowing and sand storm. The influence of the blowing on the number density of sand and dust particles is discussed. And the dust transport characteristics according to results measured by optical particle counter(OPC) and micro pulse lidar(MPL) are analyzed.
