1.
Based on FY-2 infrared images and the reanalysis data for six hours of NCEP(1°×1°),the heavy dust storm process occurred on 13 April 2007 in the middle west part of Hexi corridor is analyzed,particularly the cloud head of the descending jet was tracked and the gravitational instability,conditional symmetric instability and conditional instability are diagnosed in detail.
2007年4月13日在河西走廊中西部发生了特强沙尘暴,极大风速25m/s,最小能见度50m。
2.
Based on the past research works we theoretically analyzed the formation mechanism of heavy dust storm and discussed the action of atmospheric strong advection to heavy dust storm (black wind).
在总结过去研究结果的基础上,对特强沙尘暴的发生机制进行了进一步的理论分析,探讨了大气强对流对特强沙尘暴(黑风)形成的作用;从物理上系统解释了特强沙尘暴天气的沙尘壁特征;概述了特强沙尘暴的大气沙尘粒子尺度和垂直分布;定性评估了沙尘暴的直接和间接、短期和长期气候效应;最后,还讨论了沙尘暴研究中存在的一些关键科学问题。
5) severe sandstorm
特强沙尘暴
1.
In this paper the heavy sandstorms are that whose shortest visibility is less than 500 m, and the severe sandstorms less than 200 m.
从陕西1954—2003年所有沙尘暴记录所对应的3次或4次定时能见度观测资料中挑出最小能见度小于500m的作为强沙尘暴记录,小于200m的作为特强沙尘暴记录。
