Short summary
Many atmospheric models use shallow approximation that work well when the model top is low. As models top now reach higher layers, these approximation need to be relaxed. We develop a deep atmosphere dynamical core(GMCORE), including full deep atmosphere dynamics, and spherical geometry. The tests case with idealized baroclinic waves and tropical cyclones show that the new model reproduces known results and can alter storm trajectory, suggesting value for future high-top and tropical studies.
