Tropical Cyclone-Climate Interactions using the High-Resolution Community Earth System Model (CESM)

Usage Details
Ryan Sriver, Hui LiWe request 1,000,000 Blue Waters node hours to continue and expand our high-resolution climate model experiments investigating how Earth’s climate/weather extremes respond to increasing atmospheric carbon dioxide concentrations using a fully-coupled configuration of the high resolution Community Earth System Model (CESM). This project builds on our most recent allocation analyzing how extreme CO2 forcing can influence tropical cyclone (TC) activity. We will use the new experiments to develop and test statistical models of seasonal TC activity and variability based on relationships with large-scale climate variables, utilizing multilinear regression and deep learning methods. These simulations are only possible using Blue Waters given the large number of node hours required and the I/O challenges analyzing short term extreme weather within a global climate model over multiple decades to centuries, and the length of the model simulations required for developing the statistical predictive models.
