The GME-Aqua-Planet

hydrostatic finite difference model based on an icosahedron

icosahedron: ni = 203rd refinement: ni = 23

investigations of the interaction between small and large scale processes in global atmospheric flows

investigations on self-organization in idealized global atmospheric flows with “realistic” physics

development and testing of new convection and cloud schemes
