Evaluating the impact of the CAM 5 dynamical core in idealized tropical cyclone simulations
We implement an idealized tropical cyclone test case for high-resolution GCMs in aqua-planet mode with constant sea surface temperatures. The initial conditions are based on an initial vortex seed that is in gradient-wind and hydrostatic balance and intensifies over a 10-day period. The impact of the dynamical core on the evolution of the tropical cyclone is assessed. In particular, we investigate four dynamical cores (FV, EUL, SLD, HOMME) that are part of NCAR's hydrostatic Community Atmosphere Model CAM 5. The research thereby isolates and reveals the influences of the numerical schemes on the evolution of the cyclone.
