The El Niño‐Southern Oscillation (ENSO) has been found to be closely related to dust aerosol activities in many parts of the world. However, previous studies have rarely explored the ENSO’s impacts in the global context. In this study, the responses of the interannual variability of global atmospheric dust content to the ENSO cycle (including the eastern Pacific and central Pacific types) are examined using the MERRA‐2 atmospheric aerosol reanalysis data. The ENSO‐related tropical eastern Pacific sea surface temperature (SST) anomalies in the antecedent winter (November to January) have the most significant effect on the airborne dust content in a region from the Arabian Peninsula to Central Asia during the following spring and summer (April to July), which is identified as the key region (KR) of the ENSO’s impacts. The positive (negative) tropical eastern Pacific SST anomalies in the preceding winter during the El Niño (La Niña) years correspond to significantly reduced (increased) dust column content in the following spring and summer over the KR, which was confirmed using singular value decomposition. With the above (below)‐normal winter SST anomalies in the tropical eastern Pacific, the Walker Circulation weakens (strengthens), and the divergence (convergence) over the western tropical Pacific and the convergence (divergence) over the southern tropical Indian Ocean in the lower troposphere are strengthened, which facilitate (restrain) the southward diffusion of airborne dust in the KR. Meanwhile, the increased (decreased) precipitation and soil moisture and the corresponding vegetation conditions help limit (promote) the dust emission in the KR during the El Niño (La Niña) years.

ENSO对尘埃活动的全球影响，重点是从阿拉伯半岛到中亚的关键地区

在世界许多地方，已发现厄尔尼诺-南方涛动（ENSO）与粉尘气溶胶活动密切相关。但是，以前的研究很少探讨ENSO在全球范围内的影响。在这项研究中，使用MERRA-2大气气溶胶再分析数据检查了全球大气尘埃含量对ENSO周期（包括东太平洋和中太平洋类型）的年际变化响应。在接下来的春季和夏季，从冬季（11月至1月）的ENSO相关热带东太平洋海表温度（SST）异常对阿拉伯半岛至中亚地区的空气传播尘埃含量影响最大（ 4月至7月），该区域被确定为ENSO影响的关键区域（KR）。在厄尔尼诺（LaNiña）年之前的冬季，东太平洋热带SST的正（负）异常对应于KR之后的春季和夏季，尘埃柱含量显着减少（增加），这已通过奇异值分解得到了证实。 。在热带东部太平洋，冬季出现以上（以下）正常的冬季海温异常，沃克环流减弱（增强），西部热带太平洋的辐散（收敛），以及热带印度洋南部的辐合（辐散）。低层对流层得到加强，这有利于（抑制）KR中的机载尘埃向南扩散。同时，
