Abstract: discontinuous Galerkin model solving the shallow-water equations on the sphere is presented. It captures the dynamically varying key aspects of the flows by having the advantageous ability to locally modify the mesh as ...

Abstract: The adequate representation of the dominant intraseasonal and synoptic-scale variability in the tropics, characterized by the Madden?Julian oscillation (MJO) and convectively coupled waves, is still problematic in current ...

Abstract: In an effort to study the applicability of adaptive mesh refinement (AMR) techniques to atmospheric models, an interpolation-based spectral element shallow-water model on a cubed-sphere grid is compared to a block-structured ...
