Unification of the mathematical model of elastic perfectly plastic solids: a convex analysis approach
Tahar Z Boulmezaoud, Boualem Khouider
A new mathematical formulation for the constitutive laws governing elastic perfectly plastic materials is proposed here. In particular, it is shown that the elastic strain rate and…
QG-DL: Dynamics of a diabatic layer in the quasi-geostrophic framework
Rupert Klein, Lisa Schielicke, Stephan Pfahl +1
Quasi-geostrophic (QG) theory describes the dynamics of synoptic scale flows in the trophosphere that are balanced with respect to both acoustic and internal gravity waves. Within…
Coastal Tropical Convection in a Stochastic Modeling Framework
Martin Bergemann, Boualem Khouider, Christian Jakob
Recent research has suggested that the overall dependence of convection near coasts on large-scale atmospheric conditions is weaker than over the open ocean or inland areas. This i…
A Stochastic Closure for Two-Moment Bulk Microphysics of Warm Clouds: Part II, Validation
David Collins, Boualem Khouider
The representation of clouds and associated processes of rain and snow formation remains one of the major uncertainties in climate and weather prediction models. In a companion pap…
A Stochastic Closure for Two-Moment Bulk Microphysics of Warm Clouds: Part I, Derivations
David Collins, Boualem Khouider
We propose a mathematical methodology to derive a stochastic parameterization of bulk warm cloud micro-physics properties. Unlike previous bulk parameterizations, the stochastic pa…
An efficient numerical algorithm for the L2 optimal transport problem with applications to image processing
Louis-Philippe Saumier, Martial Agueh, Boualem Khouider
We present a numerical method to solve the optimal transport problem with a quadratic cost when the source and target measures are periodic probability densities. This method is ba…
