The response of tropical cyclone activity to global warming in the Community Earth System Model (CESM)

Usage Details

We propose to use Blue Waters to investigate the response of global tropical cyclone activity to changing greenhouse gas forcing (e.g. atmospheric carbon dioxide concentrations) using a fully-coupled configuration of the high resolution Community Earth System Model (CESM). This project builds on the PIs' recent Blue Waters allocation analyzing tropical cyclones in high-resolution configurations of CESM under constant present-day climate conditions for different coupled and uncoupled configurations. Here we propose to expand these current simulations into a more comprehensive climate change experiment. The model simulations will be performed by co-PI Li, who will be fully supported for the duration of the project in part by a NCSA Faculty Fellowship awarded to PI Sriver. The new simulations will provide a critical next step in settling the longstanding debate about the role of the tropical cyclones in influencing Earth's climate and how these events may change in the future.
