Advancing the understanding of the IAS with the Community Earth System Model

National Center for Atmospheric Research
Session I: Identifying opportunities and challenges of observing and modeling IAS variability and its teleconnections
Simulations with the Community Earth System Model (CESM) are produced on a yearly basis at the National Center for Atmospheric Research (NCAR). Staff at NCAR's Climate and Global Dynamics Laboratory (CGD) routinely runs the CESM as part of model development efforts or to meet requirements of experiment protocols. In recent years some outstanding CESM simulations have been completed at NCAR that are great resources for the understanding of climate processes in the Americas and the Intra-Americas Sea (IAS) region. This presentation provides an introduction to those various sets of global CESM simulations. Learning about those simulations allows for the proper selection of experiments for a given research project. Aspects that can be addressed with these experiments span the quantification of ensemble statistics in the Americas, the analysis of oceanic Gulf of Mexico processes at 10-km resolution, and the impact of climate change in the IAS with and without carbon dioxide's radiative forcing. In addition, these CESM simulations have biogeochemistry fields available, thereby allowing for the analysis of the link between IAS physical processes and biogeochemical processes.
