Gustiness and Coherent Structure of Strong Winds and Their Role in Dust Emission and Entrainment 总被引:2,自引:0,他引:2
After the passage of a cold front,spring in northern China,the outbreak of strong wind is often accompanied by dust emissions.Through analyses of data in the atmospheric boundary layer during a typical case,it is revealed there are rather regular gust wave packets superimposed on the basic strong wind flow.The gust-wind wave packets have a period equal to around 3-6 mins and possess coherent structure.As the vertical transport of momentum is decomposed into separate parts by(a) basic flow,(b) gust-wind,and(... 相似文献
