Leveraging data-driven weather models for improving numerical weather prediction skill through large-scale spectral nudging
Syed Zahid Husain, Leo Separovic, Jean-François Caron +9
Operational meteorological forecasting has long relied on physics-based numerical weather prediction (NWP) models. Recently, this landscape has faced disruption by the advent of da…

Addendum: Hidden symmetries, trivial conservation laws and Casimir invariants in geophysical fluid dynamics (2018 J. Phys. Commun. 2 115018)
Martin Charron, Ayrton Zadra
An extension is proposed to the internal symmetry transformations associated with mass, entropy and other Clebsch-related conservation in geophysical fluid dynamics. Those symmetry…

On the dissociation between potential vorticity conservation and symmetries
Martin Charron, Ayrton Zadra
Using a four-dimensional manifestly covariant formalism suitable for classical fluid dynamics, it is shown that the conservation of potential vorticity is not associated with any s…
