  1. Multi-scale Aerosol-Climate Model Simulates Enhanced Pacific Storm Track from Aerosols • Objective • Examine the impact of anthropogenic aerosols on Pacific storm track in global climate models • Approach • Use a multi-scale aerosol climate model that embeds 2D cloud-resolving model to explicitly simulate aerosol effects on deep clouds • Compare pre-industrial (PI) and present-day (PD) aerosol effects on Pacific storm track in the multi-scale aerosol-climate model and a conventional aerosol-climate model The difference in the frequency of cloud-top occurrence % between pre-industrial and present-day from aerosols simulated in the PNNL-MMF. • Impact • Provide for the first time a global perspective of the impacts of Asian pollution outflows from GCMs • The multi-scale modeling framework is essential in revealing the aerosol invigoration effect of deep convective clouds on the global scale Wang Y, M Wang, R Zhang, S Ghan, Y Lin, J Hu, B Pan, M Levy, J Jiang, M Molina. 2014. “Assessing the impact of anthropogenic aerosols on Pacific storm track using a multi-scale global climate model.” Proceedings of the National Academy of Sciences, early edition online.
