Diagnosing the 11‐year solar cycle's influence on the East Atlantic pattern

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
A previously unidentified solar‐cycle response in the East Atlantic pattern is found in late winter at lag +3 years with larger amplitude than the NAO response. A statistically significant NAO response to the solar cycle is seen in late winter at lag 0 years.

Equatorially trapped Rossby waves in radiative stars

open access: yes, 2023
Observations by recent space missions reported the detection of Rossby waves (r‐modes) in light curves of many stars (mostly A, B, and F spectral types) with outer radiative envelope.

Identification of Rossby Atmosphere-Tropical Cyclone in Eastern Indonesian Waters

open access: yesJurnal Ilmu Dasar
Recent research has revealed that tropical cyclones can develop over eastern Indonesian waters influenced by marine heatwaves and Rossby waves in the atmosphere.

Benjamin-Ono-Burgers-MKdV Equation for Algebraic Rossby Solitary Waves in Stratified Fluids and Conservation Laws

open access: yesAbstract and Applied Analysis, 2014
In the paper, by using multiple-scale method, the Benjamin-Ono-Burgers-MKdV (BO-B-MKdV) equation is obtained which governs algebraic Rossby solitary waves in stratified fluids. This equation is first derived for Rossby waves. By analysis and calculation,

Rossby wave instability with self-gravity [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2012
The Rossby wave instability (RWI) in non-self-gravitating discs can be triggered by a bump at a radius $r_0$ in the disc surface mass-density (which is proportional to the inverse potential vorticity). It gives rise to a growing non-axisymmetric perturbation [$\propto \exp(imϕ)$, $m=1,2..$] in the vicinity of $r_0$ consisting of anticyclonic vortices ...

Lagrangian analysis of two flavours of Central European heatwaves: Formation under omega blocking versus initiation by subtropical ridges

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We investigate whether Central European heatwaves (HWs) forming under omega blocking differ from those enabled by subtropical ridges, in terms of both air‐mass origin and processes warming air parcels along their way. Using ERA5‐based backward trajectories and a Lagrangian temperature anomaly decomposition, we identify significant differences in the ...

Rossby Waves With Linear Topography In Barotropic Fluids

open access: yes, 2008
Rossby waves are the most important waves in the atmosphere and ocean, and are parts of a large-scale system in fluid. The theory and observation show that, they satisfy quasi-geostrophic and quasi-static equilibrium approximations.

One-dimensional weakly nonlinear model equations for Rossby waves [PDF]

open access: yes, 2021
In this study we explore several possibilities for modelling weakly nonlinear Rossby waves in fluid of constant depth, which propagate predominantly in one direction.

Trajectory analysis of the propagation of Rossby waves on the Earth’s δ-surface

open access: yesAtmospheric and Oceanic Science Letters, 2018
The propagation of Rossby waves on the Earth’s δ-surface is discussed in a reference frame propagation with the zonal phase speed of the wave. In this reference frame, trajectories and streamlines coincide; the propagation of Rossby waves has a different

Forecast‐Error Diagnostics in Neural Weather Models

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Deep learning weather prediction models enable efficient forecast‐error diagnostics through auto‐differentiation and low computational cost. We apply grid‐point relaxation and gradient‐based error sensitivity to identify key forecast‐error sources. Results show that medium‐range forecasts in the midlatitudes benefit most from relaxing the stratosphere ...
