A conservative numerical scheme for the multilayer shallow‐water equations on unstructured meshes

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
An energy‐conserving scheme is derived for the multilayer shallow water model, making use of the direct connection between energy conservation and the skew symmetry of the Poisson bracket for the model. A new mechanism is proposed to prevent layer interface outcropping.

Global representation of extratropical cyclone precipitation and future trends in CMIP6 models

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We use a cyclone‐tracking algorithm to study precipitation produced by extratropical cyclones and identify five global hotspots of extreme precipitation: the well‐known Pacific and Atlantic storm tracks in the Northern Hemisphere and three distinct hotspots in the Southern Hemisphere, located at low latitudes to the east of the major landmasses of ...

Weather features drive free‐tropospheric baroclinicity variability in the North Atlantic storm track

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We show that synoptic weather features, such as extratropical cyclones, fronts, and atmospheric rivers, contribute to more than half of the total variability of free‐tropospheric baroclinicity in the North Atlantic storm track, despite their limited spatial and temporal extent.

Toward Useful Quantum Kernels

open access: yesAdvanced Quantum Technologies, EarlyView.
The hybrid approach to Quantum Supervised Machine Learning is compatible with Noisy Intermediate Scale Quantum (NISQ) devices but hardly useful. Pure quantum kernels requiring fault‐tolerant quantum computers are more promising. Examples are kernels computed by means of the Quantum Fourier Transform (QFT) and kernels defined via the calculation of ...

Distributed Leader‐Following Formation of Discrete‐Time Multi‐Agent LPV Systems

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper addresses the leader‐following formation consensus problem for multi‐agent systems (MASs) with agents represented by discrete‐time linear parameter‐varying (LPV) models. The scenario where each agent can be modeled with distinct time‐varying scheduling parameters is investigated with respect to compensation signals.
