Towards a finite volume discretization of the atmospheric surface layer consistent with physical theory
Simon Clément, Florian Lemarié, Eric Blayo
We study an atmospheric column and its discretization. Because of numerical considerations, the column must be divided into two parts: (1) a surface layer, excluded from the comput…
Discrete analysis of Schwarz Waveform Relaxation for a simplified air-sea coupling problem with nonlinear transmission conditions
Simon Clement, Florian Lemarié, Eric Blayo
In this study we present a non-overlapping Schwarz waveform relaxation (SWR) method applied to a one dimensional model problem representative of the coupling between the ocean and…
Recent progress and review of issues related to Physics Dynamics Coupling in geophysical models
Markus Gross, Hui Wan, Philip J. Rasch +19
Geophysical models of the atmosphere and ocean invariably involve parameterizations. These represent two distinct areas: Subgrid processes that the model cannot resolve, and diabat…
Design and analysis of a Schwarz coupling method for a dimensionally heterogeneous problem
Manel Tayachi Pigeonnat, Antoine Rousseau, Eric Blayo +2
In the present work, we study and analyze an efficient iterative coupling method for a dimensionally heterogeneous problem . We consider the case of 2-D Laplace equation with non s…
A reduced-order strategy for 4D-Var data assimilation
Céline Robert, S. Durbiano, Eric Blayo +3
This paper presents a reduced-order approach for four-dimensional variational data assimilation, based on a prior EO F analysis of a model trajectory. This method implies two main…
Reduced-order 4D-Var: a preconditioner for the Incremental 4D-Var data assimilation method
Céline Robert, Eric Blayo, Jacques Verron
This study demonstrates how the incremental 4D-Var data assimilation method can be applied efficiently preconditione d in an application to an oceanographic problem. The approach c…
