对2012年3月28日至4月2日发生在东北亚地区的沙尘天气的分布和输送进行了研究。研究中使用了地表附近小于10微米的颗粒物（PM10）数据以及从地面到18公里的光探测和测距（LiDAR）测量数据。2012年3月28日，蒙古南部和中国北方上空发生了一次强沙尘天气，大范围的沙尘在几天内从源区向东南方向向日本移动。沙尘从发源地经过两天后到达日本。激光雷达对尘埃垂直分布的测量结果显示，大气层低层的尘埃厚度为1至2公里，并随着与源区距离的增加而增加。
The distribution and transport of windblown dust that occurred in Northeast Asia from 28 March to 2 April 2012 was investigated. Data of particulate matter less than 10 micrometers (PM10) near the surface and light detection and ranging (LiDAR) measurements from the ground up to 18 km were used in the study. A severe dust event originated over southern Mongolia and northern China on 28 March 2012, and the widespread dust moved from the source area southeastward toward Japan over several days. Windblown dust reached Japan after two days from the originating area. LiDAR measurements of the vertical distribution of the dust were one to two km thick in the lower layer of the atmosphere, and increased with the increasing distance from the source area.
