Journal of Computational Physics, 2019 We consider numerical approximation of the degenerate advection-diffusion equation, which is formally parabolic but may exhibit hyperbolic behavior. We develop both explicit and implicit finite volume weighted essentially non-oscillatory (WENO) schemes ...

Dynamics of Downdrafts Around a Growing Convective Cloud: A Numerical Study
Journal of Geophysical Research: Atmospheres, Volume 130, Issue 22, 28 November 2025.Abstract We examine the dynamics of cloud‐edge downdrafts over the growth phase of isolated cumuli, combining Eulerian and Lagrangian analyses. As in previous studies, our results show that growing cumuli are surrounded by downdrafts linked to cloud‐scale quasi‐toroidal circulations at all times at middle and upper cloud levels consistent with the ...

ERF: Energy Research and Forecasting Model
Journal of Advances in Modeling Earth Systems, Volume 17, Issue 11, November 2025.Abstract High performance computing (HPC) architectures have undergone rapid development in recent years. As a result, established software suites face an ever increasing challenge to remain performant on and portable across modern systems. Many of the widely adopted atmospheric modeling codes cannot fully (or in some cases, at all) leverage the ...

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 11, November 2025.Abstract Seagrass meadows fulfill many essential ecological functions, of which an important one is to stabilize sediment. Therefore, they are perceived as a nature‐based addition or alternative to conventional rigid coastal protection. The impact of seagrass meadows depends on their morphology, such as canopy height, shoot density, and spatial extent.

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract Large‐eddy simulation (LES) has been an indispensable modeling tool for the study of shallow cumulus (ShCu) clouds. However, a recent study uncovered omnipresent spurious pressure waves around simulated ShCu clouds by three compressible community LES models, suggesting a potentially common issue.

Investigation of WENO schemes for 3D unstructured grids
Computer Assisted Methods in Engineering and Science, 2022 This paper paper discusses accuracy of WENO reconstruction used for unstructured grids and applied to two common discretization approaches within Finite Volume Method (FVM). They are Cell Centered and Vertex Centered methods.

ComputationIn this paper, we propose the MUSWENO scheme, a novel mapped weighted essentially non-oscillatory (WENO) method that employs unequal-sized stencils, for solving nonlinear degenerate parabolic equations.
