"Application of a cloud-resolving model to climate-change problems"

Presented by Marat Khairoutdinov, SUNY Stony Brook

Thursday, November 30, 2017, 11:00 pm — Conference Room Bldg 815E

Convection contributes significantly to the uncertainty of the climate feedbacks to the forcing due to increasing presence of anthropogenic green-house gases as simulated by the contemporary global climate models (GCMs). In nature, convection tends to self-organize on larger scales, from squall-lines to tropical cyclones (TCs), or even planetary-scale systems associated with the Madden-Julian Oscillation. Cloud-resolving models (CRMs) have been used to gain some insight into these important issues. In this talk, the results of application of a particular CRM, the System for Atmospheric Modeling, or SAM, to several problems involving self-organized tropical convection among others will be presented. In particular, preliminary results of global cloud-resolving simulations with a 4 km horizontal grid spacing will be shown. Also, a high-resolution building-resolving LES of pollutant transport over Manhattan and simulation of tsunami in New York Harbor will be introduced as examples of urban modeling.
