Dynamical Core

The Duo-Grid and Cubed-Sphere Grid Imprinting
An efficient refinement strategy for the cubed-sphere grid that enables regional simulations in the global FV3 dynamical core without regridding.

Integrating a Three-Dimensional TKE-Based Subgrid Diffusion Scheme Into GFDL FV3
An inline 3D TKE-based subgrid diffusion scheme is embedded directly in the FV3 dynamical core, giving a unified turbulence treatment across the gray zone and large-eddy scales.
