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 ...

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 ...

An alternative reconstruction for WENO schemes with adaptive order
CoRR, 2021 We propose an alternative reconstruction for weighted essentially non-oscillatory schemes with adaptive order (WENO-AO) for solving hyperbolic conservation laws. The alternative reconstruction has a more concise form than the original WENO-AO reconstruction. Moreover, it is a strictly convex combination of polynomials with unequal degrees.

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.

Nonlinear spectral-like schemes for hybrid schemes [PDF]
, 2014 In spectral-like resolution-WENO hybrid schemes, if the switch function takes more grid points as discontinuity points, the WENO scheme is often turned on, and the numerical solutions may be too dissipative.

On the construction and properties of WENO schemes order five, seven, nine, eleven and thirteen. Part 2. Numerical examples [PDF]
Компьютерные исследования и моделирование, 2016 WENO schemes (weighted, essentially non oscillating) are currently having a wide range of applications as approximate high order schemes for discontinuous solutions of partial differential equations. These schemes are used for direct numerical simulation

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

Assessment of three WENO type schemes for nonlinear conservative flux functions [PDF]
INCAS Bulletin, 2018 This paper focuses on a new comparison of the behavior of three Weighted Essentially Non-Oscillatory (WENO) type numerical schemes for three different nonlinear fluxes, in the case of scalar conservation law.

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 ...
