On the Tropical Nature of an Intense Mediterranean Cyclone in the Ocean‐Atmosphere System

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract The Mediterranean basin hosts a large number of cyclones every year. Among them, some rare cases named medicanes present similarities with tropical cyclones but their dynamical characteristics are debated. The ocean‐atmosphere dynamics of Medicane Ianos (2020) are studied here through km‐scale fully coupled ocean‐wave‐atmosphere simulations ...

A modified fifth-order WENO scheme for hyperbolic conservation laws [PDF]

, 2016
This paper deals with a new fifth-order weighted essentially non-oscillatory (WENO) scheme improving the WENO-NS and WENO-P methods which are introduced in Ha et al. J. Comput. Phys. (2013) and Kim et al., J. Sci. Comput. (2016) respectively.

The Structure and Lifecycle of Stratified Mixing by Shear Instabilities in Continuously Forced Flows

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract The turbulent energy cascade of ocean mixing remains poorly understood at geophysically large Reynolds numbers (Re $\mathrm{R}\mathrm{e}$). Here we propose a new conceptual model for the structure of small‐scale mixing grounded in high‐resolution multibeam echosounding observations from the mouth of the Connecticut River, a shallow salt‐wedge ...

A hybrid kinetic WGVC-WENO scheme for compressible flows [PDF]

, 2021
In this paper, we propose a hybrid kinetic weighted group velocity control-weighted essentially non-oscillatory (WGVC-WENO) scheme which combines the WGVC-WENO reconstruction technique He et al. (2014) with the hybrid kinetic method proposed in Liu et al.

How Does Ice Shell Geometry Shape Ocean Dynamics on Icy Moons?

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract A poleward‐thinning ice shell can drive circulation in the subsurface oceans of icy moons by imposing a meridional temperature gradient–colder at the equator than the pole–through the freezing point suppression due to pressure. This temperature gradient sets a buoyancy gradient, whose sign depends on the thermal expansion coefficient ...

Application of a Novel High-Order WENO Scheme in LES Simulations

Applied Sciences
To achieve high-fidelity large eddy simulation (LES) predictions of complex flows while keeping computational costs manageable, this study integrates a high-order WENO-ZQ scheme into the LES framework.

Curvilinear grids for WENO methods in astrophysical simulations [PDF]

Computer Physics Communications, 2014
We investigate the applicability of curvilinear grids in the context of astrophysical simulations and WENO schemes. With the non-smooth mapping functions from Calhoun et al. (2008), we can tackle many astrophysical problems which were out of scope with the standard grids in numerical astrophysics.

A WENO Finite‐Volume Scheme for the Evolution of Potential Vorticity in Isopycnal Ocean Models

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract Ocean circulations are strongly constrained by rotation and stratification, making potential vorticity (PV) a key dynamical property. Specifically, PV is conserved following water parcels in the absence of diabatic forcing and friction—a desirable feature for isopycnal ocean models.

A high-resolution WENO scheme with multiple global smoothness indicators in compressible fluids

Results in Applied Mathematics
A novel fifth-order WENO-Z-type scheme with multiple global smoothness indicators (MGSI-WENO-Z) is proposed for compressible multi-scale flows. Unlike conventional WENO-Z schemes with a single global smoothness indicator, distinct GSIs are assigned to ...

Modelling chemical advection during magma ascent [PDF]

Geoscientific Model Development
Modelling magma transport requires robust numerical schemes for chemical advection. Current numerical schemes vary in their ability to be mass conservative, computationally efficient, and accurate.
