The circulations and affecting systems causing the 6 severe sandstorm processes in Shaanxi are all cold ( crossing ) trough from Mongolia .

本文首次系统地整理分析了陕西强沙尘暴、特强沙尘暴过程，对陕西强沙尘暴、特强沙尘暴过程的环流形势和影响系统、冷空气路径、沙尘源地和路径进行了分型。

The circulations , affecting systems , the cold air paths , the sand sources and paths which causing heavy sandstorm processes in Shaanxi are sorted .

浮尘和扬沙天气主要发生在冷锋前部，沙尘暴和特强沙尘暴主要发生在锋后的西北强风区域中。

Floating dust and blowing sand mainly occurred at the front of the cold front , and the dust storm was mainly occurred in the strong northwest wind behind the cold front .

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；

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 ) .

弱至强沙尘暴可能与盐池南部荒漠化草场植被破坏和沙漠化有关，属就地起沙类型，不能造成特强沙尘暴灾害。

Relatively weaker sandstorms maybe have relation with vegetation breakage and land desertification of the desert grassland in the south of Yanchi , and belong to the local type , so commonly cannot bring sand calamity .

使用1957&1996年40年内蒙古中西部74个地面测站沙尘暴观测资料，确定了不同范围强和特强沙尘暴标准，给出了强和特强沙尘暴过程的个例谱；

From the observation data of sandstorms over past 40 years ( 1957_1996 ) from 74 meteorological stations located in the west and middle parts of Inner Mongolia , China , 184 strong and very strong sandstorm cases with different scopes were recorded according to a given standard of intensity .

近年来强和特强的沙尘暴频繁发生，这与中国北方人类活动对地表覆盖的严重破坏，生态环境进一步恶化有关。

The recently frequent occurrences of intensive sand-dust storms were due to the following factors : human destruction to the and cover in the North of China and deteriorating ecological enironment .
