Abstract: 
I will present initial results for a three-dimensional, hydrostatic, global atmospheric model combining quadtree, horizontal adaptivity on a cubed sphere grid with a standard, layered vertical discretisation. This model is implemented within the Gerris framework (http://gfs.sf.net) and thus automatically inherits attributes such as data parallelism and load-balancing. For large-scale atmospheric simulations, I will show that quadtree-adaptivity leads to a large gain in the scaling exponent relating computational cost to the resolution of sharp frontal structures.
