Large-Amplitude Quasi-10-Day Waves in the Middle Atmosphere During Final Warmings
Geopotential height measurements from the Aura Microwave Limb Sounder between 9- and 97-km altitudes during 2004–2018 are used to examine long-period (3–20 days) wave activity during the Northern Hemisphere winter and ... -
Oblique Gravity Wave Propagation During Sudden Stratospheric Warmings
Stephan, C. C.; Schmidt, H.; Zülicke, C.; Matthias, V.
(Journal of Geophysical Research: Atmospheres, 2020)
Gravity waves (GWs) are important for coupling the mesosphere to the lower atmosphere during sudden stratospheric warmings (SSWs). Here, a minor SSW is internally generated in a simulation with the upper-atmosphere ... -
Quasi‐4‐Day Wave: Atmospheric Manifestation of the First Symmetric Rossby Normal Mode of Zonal Wavenumber 2
This paper describes global characteristics of the westward‐propagating planetary wave with a period of ∼4 days and zonal wavenumber 2, here referred to as quasi‐4‐day wave (Q4DW), which is considered to be a manifestation ... -
September 2019 Antarctic Sudden Stratospheric Warming: Quasi-6-Day Wave Burst and Ionospheric Effects

; Siddiqui, T.; Kervalishvili, G.; Laštovi?ka, J.; Kozubek, M.; Ward, W.; Themens, D. R.; Kristoffersen, S.; Alken, P.
(Geophysical Research Letters, 2020)
An exceptionally strong stationary planetary wave with Zonal Wavenumber 1 led to a sudden stratospheric warming (SSW) in the Southern Hemisphere in September 2019. Ionospheric data from European Space Agency's Swarm satellite ...
