Three‐Dimensional Numerical Simulations of Internal Tides in the Cape Verde and Senegalo‐Mauritanian Upwelling Regions

Journal of Geophysical Research: Oceans, Volume 130, Issue 11, November 2025.
Abstract Tide‐topography interactions, key drivers of upwelling and mixing, remain poorly understood within the Cape Verde area (CVA) and the Senegalo‐Mauritanian upwelling regions. Therefore, a three‐dimensional numerical model, initialized with horizontally uniform stratification and driven by barotropic tidal forcing only, is employed to study the ...

ON NONLINEAR BIHARMONIC DISPERSIVE WAVE EQUATIONS

FUDMA JOURNAL OF SCIENCES
This paper proposes and studies particular nonlinear dispersive biharmonic equation, whose related equations appear in various physical phenomena such as wave propagation in nonlinear media and plasma physics. We chose the power kind of nonlinearity as it is common in these areas.

Enclosure for the Biharmonic Equation

, 2006
In this paper we give an enclosure for the solution of the biharmonic problem and also for its gradient and Laplacian in the $L_2$-norm, respectively.

Small‐Scale, High‐Frequency Ice, and Ocean Processes in the Amundsen Sea Embayment, West Antarctica

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 11, November 2025.
Abstract In proximity of the Antarctic ice sheet, oceanic motions with different spatial structures contribute to the transport of warm water onto the continental shelf, fueling submarine ice‐shelf melting. Emerging evidence suggests that km‐sized ocean submesoscale fronts and eddies significantly impact ice‐ocean interactions on timescale of a few ...

Generalizable Neural‐Network Parameterization of Mesoscale Eddies in Idealized and Global Ocean Models

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Data‐driven methods have become popular to parameterize the effects of mesoscale eddies in ocean models. However, they perform poorly in generalization tasks and may require retuning if the grid resolution or ocean configuration changes. We address the generalization problem by enforcing physics constraints on a neural network parameterization

Air–sea interaction in medicanes with atmosphere–ocean–wave coupled regional climate simulations

Quarterly Journal of the Royal Meteorological Society, Volume 151, Issue 772, October 2025 Part A.
The atmosphere–ocean–wave coupling improved storm intensity compared to standalone atmosphere setting, which tended to overestimate wind speeds. The atmosphere–ocean coupling in medicane simulations leads to increased sea surface temperatures, which enhances evaporation and promotes the development of convective systems through increased latent heat ...

The GFDL‐CM4X Climate Model Hierarchy, Part I: Model Description and Thermal Properties

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 10, October 2025.
Abstract We present the GFDL‐CM4X (Geophysical Fluid Dynamics Laboratory Climate Model version 4X) coupled climate model hierarchy. The primary application for CM4X is to investigate ocean and sea ice physics as part of a realistic coupled Earth climate model.

Sequences of weak solutions to a fourth-order elliptic problem

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2020
This paper contains some results of existence of infinitely many solutions to an elliptic equation involving the p(x)-biharmonic operator coupled with Navier boundary conditions where the nonlinearities depend on two real parameters and do not possess ...

Tangentially biharmonic Lagrangian H-umbilical submanifolds in complex space forms

, 2014
The notion of Lagrangian $H$-umbilical submanifolds was introduced by B. Y. Chen in 1997, and these submanifolds have appeared in several important problems in the study of Lagrangian submanifolds from the Riemannian geometric point of view.
