Convergence of forecast distributions on the synoptic scale

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We investigate whether convergence of sampling uncertainty with ensemble size, as seen in convective‐scale models, is also seen in global ensembles where synoptic‐scale weather systems play a greater role. The nature of convergence was indeed similar, as shown in this figure where the 50‐member ensemble from a single grid point was large enough for the

Nonabelian fluids and helicities

Journal of High Energy Physics
In analogy with the non-Abelian gauge helicities conserved in time for “null fields”, that we have defined previously, in this paper we first define non-Abelian fluid helicities and then total non-Abelian helicities for combined non-Abelian fluid and ...

On the Boundary Conditions in Deformed Quantum Mechanics with Minimal Length Uncertainty

Advances in High Energy Physics, 2013
We find the coordinate space wave functions, maximal localization states, and quasiposition wave functions in a GUP framework that implies a minimal length uncertainty using a formally self-adjoint representation.

Introduction to co-split Lie algebras

, 2010
In this work, we introduce a new concept which is obtained by defining a new compatibility condition between Lie algebras and Lie coalgebras. With this terminology, we describe the interrelation between the Killing form and the adjoint representation in ...

The importance of the timing of anchor observations in 4D variational bias correction: Theory and idealised experiments

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The successful assimilation of radiance data in modern numerical weather prediction relies heavily on the correction of radiance biases through the use of VarBC. We introduce a new theory that explains how a network of unbiased “anchor” observations can help mitigate the impact of model biases in VarBC.

Macdonald deformation of Vogel's universality and link hyperpolynomials

Physics Letters B
Vogel's universality implies a unified description of the adjoint sector of representation theory for simple Lie algebras in terms of three parameters α,β,γ, which are homogeneous coordinates of Vogel's plane. Actually this is true (if at all) only for a

A representative solution to m-order linear ordinary differential equation with nonlocal conditions by green's functional concept

Mathematical Modelling and Analysis, 2012
In this work, we investigate a linear completely nonhomogeneous nonlocal multipoint problem for an m-order ordinary differential equation with generally variable nonsmooth coefficients satisfying some general properties such as p-integrability and ...

An overview of drifting‐buoy deployments in atmospheric river reconnaissance from 2019 to 2024

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This article provides an overview of the drifting‐buoy deployments from 2019 to 2024 in the Atmospheric River Reconnaissance (AR Recon) observational campaign. The 309 buoys deployed have increased sea‐level atmospheric pressure coverage across the North Pacific and most buoys' pressure observations reduced forecast error in terms of the Forecast ...

Classification of compactified su(N c ) gauge theories with fermions in all representations

Journal of High Energy Physics, 2017
We classify su(N c ) gauge theories on ℝ3×S1 $$ {\mathrm{\mathbb{R}}}^3\times {\mathbb{S}}^1 $$ with massless fermions in higher representations obeying periodic boundary conditions along S1 $$ {\mathbb{S}}^1 $$. In particular, we single out the class of

Invariant Tensors Formulae via Chord Diagrams [PDF]

, 2005
We provide an explicit algorithm to calculate invariant tensors for the adjoint representation of the simple Lie algebra $sl(n)$, as well as arbitrary representation in terms of roots.
