Properties of Solar Rossby Waves from Normal Mode Coupling and Characterizing Its Systematics [PDF]
Astrophysical Journal, 2019 Rossby waves play an important role in mediating the angular momentum of rotating spherical fluids, creating weather on Earth and tuning exoplanet orbits in distant stellar systems. Their recent discovery in the solar convection zone provides an exciting

Green’s functions for Rossby waves [PDF]
Journal of Fluid Mechanics, 2017 Compact solutions are presented for planetary, non-divergent, barotropic Rossby waves generated by (i) an impulsive point source and (ii) a sustained point source of curl of wind stress. Previously, only cumbersome integral expressions were known, rendering them practically useless.

Frontiers in Astronomy and Space Sciences, 2022 Rossby waves have been recently recognised for their role in the large-scale spatio-temporal organisation of the solar magnetic activity. Here, we study the propagation of magnetohydrodynamic Rossby waves in a thin layer, representing the solar ...

Time-distance helioseismology of solar Rossby waves [PDF]
Astronomy & Astrophysics, 2018 Context. Solar Rossby waves (r modes) have recently been discovered in the near-surface horizontal flow field using the techniques of granulation-tracking and ring-diagram analysis applied to six years of SDO/HMI data. Aims.

Simulating Properties of “Seasonal” Variability in Solar Activity and Space Weather Impacts
Frontiers in Astronomy and Space Sciences, 2021 Solar short-term, quasi-annual variability within a decadal sunspot-cycle has recently been observed to strongly correlate with major class solar flares, resulting into quasi-periodic space weather “seasons.” In search for the origin of this quasi ...

Generation of zonal flows by Rossby waves in the atmosphere [PDF]
Nonlinear Processes in Geophysics, 2004 A novel mechanism for the short-scale Rossby waves interacting with long-scale zonal flows in the Earth's atmosphere is studied. The model is based on the parametric excitation of convective cells by finite amplitude Rossby waves. We use a set of coupled

On the forcings of the unusual Quasi-Biennial Oscillation structure in February 2016 [PDF]
Atmospheric Chemistry and Physics, 2020 The westerly phase of the stratospheric Quasi-Biennial Oscillation (QBO) was reversed during Northern Hemisphere winter 2015/2016 for the first time since records began in 1953.

Abstract and Applied Analysis, 2014 We solve the so-called dissipative nonlinear Schrödinger equation by means of multiple scales analysis and perturbation method to describe envelope solitary Rossby waves with dissipation effect in stratified fluids.

Tropical rainfall, Rossby waves and regional winter climate predictions
, 2017 Skilful climate predictions of the winter North Atlantic Oscillation and Arctic Oscillation out to a few months ahead have recently been demonstrated, but the source of this predictability remains largely unknown.
