Periods of planetary waves in geomagnetic variations [PDF]

open access: yesAnnales 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.

Different Relationships between Arctic Oscillation and Ozone in the Stratosphere over the Arctic in January and February

open access: yesAtmosphere, 2021
We compare the relationship between the Arctic Oscillation (AO) and ozone concentration in the lower stratosphere over the Arctic during 1980–1994 (P1) and 2007–2019 (P2) in January and February using reanalysis datasets.

Mesospheric Inversion Layers at Mid-Latitudes and Coincident Changes of Ozone, Water Vapour and Horizontal Wind in the Middle Atmosphere

open access: yesAtmosphere, 2018
We analyse middle atmospheric profiles of temperature, geopotential height, water vapour volume mixing ratio, and ozone volume mixing ratio above Bern (46.95 ∘ N, 7.44 ∘ E).

Radiative effects of ozone waves on the Northern Hemisphere polar vortex and its modulation by the QBO [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
The radiative effects induced by the zonally asymmetric part of the ozone field have been shown to significantly change the temperature of the NH winter polar cap, and correspondingly the strength of the polar vortex.

Breaking planetary waves in the stratosphere

open access: yesNature, 1983
Satellite-borne IR radiometers are turning the Earth's stratosphere into one of the best available outdoor laboratories for observing the large-scale dynamics of a rotating, heterogeneous fluid under gravity. New insight is being gained not only into stratospheric dynamics as such, with its implications for pollutant behaviour and the ozone layer, but ...

Effects of planetary wave‐breaking on the seasonal variation of total column ozone

open access: yesGeophysical Research Letters, 2000
The effects of planetary wave breaking on the seasonal variation of total column ozone are investigated using a zonally averaged chemical‐radiative‐transport model of the atmosphere.

Antarctic planetary wave spectrum under different polar vortex conditions in 2019 and 2020 based on total ozone column data

open access: yesУкраїнський антарктичний журнал, 2022
We examine the zonal wavenumber spectrum of planetary (Rossby) waves in the atmosphere above Antarctica in each of two contrasting years: in 2019, when there was a sudden stratospheric warming (SSW), and in 2020 when the Antarctic stratospheric vortex ...

Wave activity of the mesosphere in the planetary wave range according to OH (3-1) emission observations at Maimaga and Tiksi stations for 2015–2020

open access: yesSolar-Terrestrial Physics, 2022
The article compares the interannual variability of the atmosphere at the OH glow height, which can be associated with planetary wave propagation, at stations spaced in latitude. As a characteristic reflecting planetary wave activity we consider standard

Travelling Planetary Waves [PDF]

open access: yesTellus, 1964
The oscillation of longitudinal position of the very long atmospheric waves, of wave-number 1, 2, and 3 has been described by KUBOTA and IIDA (1954), ELIASEN (1958), and others. In this note the motions of these waves are further examined, the data being Fourier zonal harmonics of the 500 mb height at latitudes 40", 50 ", and 60" N for the period ...

Multiple satellite observations of oceanic planetary waves: techniques and findings [PDF]

open access: yes, 2003
Recent satellite-based observations of oceanic planetary waves have improved our knowledge of the wave properties and lead to advancements in the theory.
