英文摘要	Usually the Arctic is relatively free of anthropogenic influence in summer, which means that particles from natural sources can be the most significant nuclei for cloud droplets. However, this is not the case during anomalously warm-air intrusions when the air origin comes from lower latitudes. In this modeling study, we investigate the effect of mid-latitude pollution inflow (anthropogenic and biomass burning [BB]) on the aerosol-cloud-radiation interactions during an episode of extreme warm-air advection. This particular episode resulted in anomalously high air temperatures over the East Siberian Sea and has accelerated sea-ice melting. The impact of different emission sources on aerosol vertical distribution, chemical composition, cloud formation, and radiation budget is examined using the Weather Research and Forecasting model, fully coupled with chemistry. Elevated turbulent clouds that occurred at the beginning of the episode are found to be more sensitive to aerosol variations and their negative feedback on supersaturation, compared to stably stratified fog layers that were dominant during the core period. Omission of either anthropogenic or BB source results in decreased cloud liquid water and cloud droplet concentrations; however, these changes are not substantially large to significantly modify the net surface radiation budget. Significant reduction of the net surface radiation is only observed if both anthropogenic and BB transported pollution reaches the area of interest. © 2021. American Geophysical Union.
