Cluster Dynamics of Planetary Waves [PDF]
EPL (Europhysics Letters), 2008 The dynamics of nonlinear atmospheric planetary waves is determined by a small number of independent wave clusters consisting of a few connected resonant triads.

Stratospheric sudden warming effects on winds and temperature in the middle atmosphere at middle and low latitudes: a study using WACCM [PDF]
Annales Geophysicae, 2014 A stratospheric sudden warming (SSW) is a dynamical phenomenon of the wintertime stratosphere caused by the interaction between planetary Rossby waves propagating from the troposphere and the stratospheric zonal-mean flow.

Gravitational waves emitted by extrasolar planetary systems [PDF]
International Journal of Modern Physics D, 2000 In this paper we consider the Extra-solar Planetary Systems recently discovered in our Galaxy as potential sources of gravitational waves. We estimate the frequency and characteristic amplitude of the radiation they emit due to the orbital motion, using ...

The global atmospheric energy transport analysed by a wavelength-based scale separation [PDF]
Weather and Climate Dynamics, 2023 The atmosphere transports energy polewards by circulation cells and eddies. To the present day, there has been a knowledge gap regarding the preferred spatial scales and physical mechanisms of eddy energy transport.

Reviews of Modern Plasma Physics, 2022 AbstractThis Special Topic focuses on magnetohydrodynamic (MHD) processes in the deep interiors of planets, in which their fluid dynamos are in operation. The dynamo-generated, global, magnetic fields provide a background for our solar-terrestrial environment.

Geophysical Research Letters, 2023 Extreme events have become more frequent in the Northern Hemisphere mid‐latitudes in recent decades, hugely impacting the ecosystem and society. The quasi‐resonance amplification (QRA) of planetary waves is considered one of the dynamic mechanisms ...

A case study of mesospheric planetary waves observed over a three-radar network using empirical mode decomposition [PDF]
Annales Geophysicae, 2018 In this paper an attempt is made to study equatorial Kelvin waves using a network of three radars: Kototabang (0.204° S, 100.320° E) meteor radar, Pameungpeuk (7.646° S, 107.688° E) medium-frequency radar, and Pontianak (0.003° S, 109.367° E) medium-

Dynamical evolution of a minor sudden stratospheric warming in the Southern Hemisphere in 2019 [PDF]
Atmospheric Chemistry and Physics, 2022 A major strong sudden stratospheric warming (SSW) occurred in the Southern Hemisphere (SH) stratosphere in 2002 (hereafter referred to as SSW2002), which is one of the most unusual winters in the SH.

Electromagnetic oscillations of the Earth's upper atmosphere (review) [PDF]
Annales Geophysicae, 2010 A complete theory of low-frequency MHD oscillations of the Earth's weakly ionized ionosphere is formulated. Peculiarities of excitation and propagation of electromagnetic acoustic-gravity, MHD and planetary waves are considered in the Earth's ...

Periods of planetary waves in geomagnetic variations [PDF]
Annales Geophysicae, 1995 Periods of planetary waves, especially the 10- and 16-day waves, were found in Fourier analyses of 10-year geomagnetic time series from two mid-latitude stations in the northern hemisphere.
