Weakening of Antarctic stratospheric planetary wave activities in early austral spring since the early 2000s: a response to sea surface temperature trends [PDF]
Atmospheric Chemistry and Physics, 2022 Using multiple reanalysis datasets and modeling simulations, the trends of Antarctic stratospheric planetary wave activities in early austral spring since the early 2000s are investigated in this study.

A model of mid-latitude E-region plasma convergence inside a planetary wave cyclonic vortex [PDF]
Annales Geophysicae, 2002 Recently, Shalimov et al. (1999) proposed a new mechanism for large-scale accumulation of long-lived metallic ions in the mid-latitude ionosphere driven by planetary waves in the lower thermosphere.

Tropopause Dynamics and Planetary Waves [PDF]
Journal of the Atmospheric Sciences, 1994 Abstract A simple model of the large-scale atmospheric circulation is studied. The model is based on the observation that the potential vorticity changes rapidly at the tropopause. This observation underlies the assumption that the potential vorticity on an isentropic surface, cutting through the tropopause, is piecewise uniform with a discontinuity at

Inter-annual variations of 6.5-day planetary waves and their relations with QBO
Earth and Planetary Physics, 2022 This paper studies inter-annual variations of 6.5-Day Waves (6.5DWs) observed at altitudes 20−110 km between 52°S−52°N latitudes during March 2002−January 2021, and how these variations were related to the equatorial stratospheric Quasi-Biennial ...

Impact of the Mt. Pinatubo volcaniceruption on the lower ionosphere andatmospheric waves over Central Europe [PDF]
Annals of Geophysics, 2003 The very strong volcanic eruption of Mt. Pinatubo in June 1991 directly affected the troposphere and lower and middle stratosphere. Here we look at its effects in the mesopause region as revealed by the radio wave absorption measurements in the lower ...

Tropopause-level planetary wave source and its role in two-way troposphere–stratosphere coupling [PDF]
Weather and Climate Dynamics, 2020 Atmospheric planetary waves play a fundamental role in driving stratospheric dynamics, including sudden stratospheric warming (SSW) events. It is well established that the bulk of the planetary wave activity originates near the surface.

Planetary Wave Spectrum in the Stratosphere–Mesosphere during Sudden Stratospheric Warming 2018
Remote Sensing, 2021 The planetary wave activity in the stratosphere–mesosphere during the Arctic major Sudden Stratospheric Warming (SSW) in February 2018 is discussed on the basis of microwave radiometer (MWR) measurements of carbon monoxide (CO) above Kharkiv, Ukraine (50.

Influence of subtropical Rossby wave trains on planetary wave activity over Antarctica in September 2002 [PDF]
Tellus: Series A, Dynamic Meteorology and Oceanography, 2015 At the beginning of September 2002, strong convection processes over south-eastern Indonesia and over south-eastern Africa have been observed. Due to the strong upper tropospheric divergent outflow, two Rossby wave trains (RWTs) were generated.
