Compact Central WENO Schemes for Multidimensional Conservation Laws [PDF]
We present a new third-order central scheme for approximating solutions of systems of conservation laws in one and two space dimensions. In the spirit of Godunov-type schemes, our method is based on reconstructing a piecewise-polynomial interpolant from cell-averages which is then advanced exactly in time.

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

Efficient WENO library for OpenFOAM
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

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

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

Optimized Weighted Essentially Nonoscillatory Third-Order Schemes for Hyperbolic Conservation Laws
We describe briefly how a third-order Weighted Essentially Nonoscillatory (WENO) scheme is derived by coupling a WENO spatial discretization scheme with a temporal integration scheme. The scheme is termed WENO3.

An Adaptive WENO Collocation Method for Differential Equations with Random Coefficients
The stochastic collocation method for solving differential equations with random inputs has gained lots of popularity in many applications, since such a scheme exhibits exponential convergence with smooth solutions in the random space.

Formation and Arrest of a Surface Density Front via Strain‐Driven Frontogenesis
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 ...
