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.

Integrating Ice Analyses and Varying Floe Size Parameterization Into Great Lakes Ice Prediction

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Accurate prediction of Great Lakes ice cover is critical for regional weather, navigation support, and safety. Current operational models often exhibit biases, such as over‐prediction of ice concentration and delayed spring melt, potentially due to simplified parameterizations.

Influence of the inlet boundary conditions on the LES performance for the cavity flow benchmark [PDF]

E3S Web of Conferences
A cavity flow consists of one air inlet and one outlet slot. The inlet slot is positioned in the upper left corner of the cavity, whereas the outlet slot is located in the lower right. This cavity flow is representative of mixing ventilation.

When Coriolis Matters: Defining Ranges for Lake Upwelling With a New Conceptual Model

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Historically, two conceptual models for upwelling in stratified lakes have been used. These are the non‐rotational (2D closed basin model) and the coastal model. The former describes upwelling in small and moderate‐sized lakes, and the latter describes upwelling in the coastal ocean and large lakes.

Adaptive Smagorinsky Models: Mathematical Theory and Dynamics of Subgrid-Scale Turbulence

This paper presents a rigorous mathematical analysis of the adaptive Smagorinsky model in Large-Eddy Simulation (LES) of turbulent flows, addressing the limitations of traditional constant-coefficient approaches. The model introduces a spatially varying dissipation coefficient, $C_{S}(x) = C_{S0} e^{-\beta \Phi(x)}$, designed to reduce excessive near ...
