北方大气气溶胶分布输送对夏季风活动的作用

Effect of Atmospheric Aerosol Distribution and Transportation in Northern on Summer Monsoon Activity

最近几年,随着全球气候变暖趋势的不断加剧,气溶胶逐渐成为了影响全球气候变化的重要因素,为了全面了解和掌握影响夏季风影响程度,现以我国北方地区沙尘天气研究为例,针对气溶胶特征,在结合气溶胶传输路径的基础上,分析了北方大气气溶胶分布输送对夏季风活动的作用,结果表明:由于大气层结构不稳定,导致我国各个地区面临沙尘暴问题;与偏北路径相比,西北地区沙尘气溶胶垂直分布高度相对较高,导致西北路径沙尘污染粒较多,严重影响了气溶胶离子类型所占比例。

In recent years,with the increasing trend of global warming,aerosols have gradually become an important factor affecting global climate change.In order to fully understand and grasp the impact of the summer monsoon,this paper takes the dust weather in northern China as an example,aiming at the characteristics of aerosols and combining with the aerosol transport path,the effect of the distribution and transportation of aerosols in the northern atmosphere on the summer monsoon activity is analyzed.The results show that:due to the instability of atmospheric structure,all regions of China are faced with the problem of sandstorm;compared with the northerly path,the vertical distribution height of dust aerosol in Northwest China is relatively high,which leads to more dust pollution particles in Northwest China,and seriously affects the proportion of aerosol ion types.
