Three-level order-adaptive weighted essentially non-oscillatory schemes
Results in Applied Mathematics, 2021 Classical fifth-order weighted essentially non-oscillatory (WENO) schemes are based on reconstructions from three consecutive second-order polynomials.

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.Abstract Large‐eddy simulations (LES) are commonly employed to study small‐scale weather phenomena and to validate coarser models. Like larger‐scale weather and climate models, they contain weakly constrained parameters and use physical inputs with associated uncertainties, such as initial conditions or forcing. This study assesses the viability of the

A fourth-order entropy condition scheme for systems of hyperbolic conservation laws
Engineering Applications of Computational Fluid Mechanics, 2021 Based on the analysis of the entropy condition scheme formulation, the accuracy order comes from initial value interpolation and flux reconstruction.

Formation and Arrest of a Surface Density Front via Strain‐Driven Frontogenesis
Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Ocean fronts play a key role in the vertical transport of heat, energy and biogeochemical tracers, but their behavior and life cycle is not well‐understood, especially at smaller scales. We present a large‐eddy simulation of mixed layer frontogenesis capturing the onset of a submesoscale regime from a larger scale, rotation‐dominated front ...

The Finite Volume WENO with Lax–Wendroff Scheme for Nonlinear System of Euler Equations
Mathematics, 2018 We develop a Lax–Wendroff scheme on time discretization procedure for finite volume weighted essentially non-oscillatory schemes, which is used to simulate hyperbolic conservation law.

Efficient WENO library for OpenFOAM
SoftwareX, 2020 The weighted essentially non oscillating (WENO) concept is well established in research and its advantages are known, however, implementation details such as memory demand hindered the usage for general applications and general purpose libraries for many

DJ4Earth: Differentiable, and Performance‐Portable Earth System Modeling via Program Transformations
Journal of Advances in Modeling Earth Systems, Volume 18, Issue 5, May 2026.Abstract Differentiable Earth system models (ESMs) enable powerful applications such as sensitivity analysis, gradient‐based calibration, state estimation, boundary flux inversions, uncertainty quantification, and online machine learning. Reverse‐mode automatic differentiation (AD) efficiently provides gradients for such tasks, yet models have rarely ...

Hybrid Finite Compact-WENO Schemes for Shock Calculation
, 2007 Hybrid finite compact (FC)-WENO schemes are proposed for shock calculations. The two sub-schemes (finite compact difference scheme and WENO scheme) are hybridized by means of the similar treatment as in ENO schemes. The hybrid schemes have the advantages
