Linear wave solutions of a stochastic shallow water model
Etienne Mémin, Long Li, Noé Lahaye +2
In this paper, we investigate the wave solutions of a stochastic rotating shallow water model. This approximate model provides an interesting simple description of the interplay be…
Comparison of Stochastic Parametrization Schemes using Data Assimilation on Triad Models
Bertrand Chapron, Dan Crisan, Darryl Holm +3
In recent years, stochastic parametrizations have been ubiquitous in modelling uncertainty in fluid dynamics models. One source of model uncertainty comes from the coarse graining…
Inversion of sea surface currents from satellite-derived SST-SSH synergies with 4DVarNets
Ronan Fablet, Bertrand Chapron, Julien Le Sommer +1
Satellite altimetry is a unique way for direct observations of sea surface dynamics. This is however limited to the surface-constrained geostrophic component of sea surface velocit…
Physically Constrained Covariance Inflation from Location Uncertainty
Yicun Zhen, Valentin Resseguier, Bertrand Chapron
Motivated by the concept of ``location uncertainty", initially introduced in \cite{Memin2013FluidFD}, a scheme is sought to perturb the ``location" of a state variable at every for…
Guided Unsupervised Learning by Subaperture Decomposition for Ocean SAR Image Retrieval
Nicolae-Cătălin Ristea, Andrei Anghel, Mihai Datcu +1
Spaceborne synthetic aperture radar (SAR) can provide accurate images of the ocean surface roughness day-or-night in nearly all weather conditions, being an unique asset for many g…
Multimodal 4DVarNets for the reconstruction of sea surface dynamics from SST-SSH synergies
Ronan Fablet, Quentin Febvre, Bertrand Chapron
Due to the irregular space-time sampling of sea surface observations, the reconstruction of sea surface dynamics is a challenging inverse problem. While satellite altimetry provide…
