DOI: 10.1002/qj.4839
Abstract: We systematically validate the static local mesh refinement capabilities of a recently proposed implicit–explicit discontinuous Galerkin scheme implemented in the framework of the deal.II library. Non‐conforming meshes are employed in atmospheric flow simulations to increase… read more here.

DOI: 10.1175/jcli-d-20-0153.1
Abstract: The wintertime Southern Hemisphere extratropical circulation exhibits considerable zonal asymmetries. We investigate the roles of various surface boundary conditions in shaping the mean state using a semi-realistic, atmosphere-only climate model. We find, in agreement with… read more here.

Mechanical and thermal forcings of Asian large-scale orography on spring cloud amount and atmospheric radiation budget over East Asia

DOI: 10.1175/jcli-d-22-0797.1
Abstract: Asian large-scale orography profoundly influences circulation in the North Hemisphere. Considerable spring top-of-the-atmosphere (TOA) radiative cooling over Southeast China (SEC) is very likely related to upstream orography forcing. Here we investigate the mechanical and thermal… read more here.

DOI: 10.1175/mwr-d-24-0144.1
Abstract: Distribution of rainfall at high spatial resolutions is needed to understand the orography-rainfall relationship over complex terrains. In this work, we present rainfall distribution at 1 km × 1 km spatial resolution and its diurnal… read more here.
