TROPICAL CYCLONES IN GFDL FVGFS – IMPACTS OF DYCORE , PHYSICS , AND INITIAL CONDITIONS

A new global model using the GFDL (Geophysical Fluid Dynamics Laboratory) nonhydrostatic Finite-Volume Cubed-Sphere dynamical core (FV3) coupled to physical parameterizations from the National Center for Environmental Prediction's Global Forecast System (NCEP/GFS) was built at GFDL, named fvGFS. This modern dynamical core has been selected for National Oceanic and Atmospheric Administration’s Next Generation Global Prediction System (NGGPS) due to its accuracy, adaptability, and computational efficiency, which brings a great opportunity for the unification of weather and climate prediction systems.
