A thorough analysis of the short- and mid-term activity-related variations in the solar acoustic frequencies [PDF]
, 2016 The frequencies of the solar acoustic oscillations vary over the activity cycle. The variations in other activity proxies are found to be well correlated with the variations in the acoustic frequencies.

The tropical route of quasi-biennial oscillation (QBO) teleconnections in a climate model [PDF]
Weather and Climate Dynamics, 2022 The influence of the quasi-biennial oscillation (QBO) on tropical climate is demonstrated using 500-year pre-industrial control simulations from the Met Office Hadley Centre model.

The impact of increasing stratospheric radiative damping on the quasi-biennial oscillation period [PDF]
Atmospheric Chemistry and Physics, 2021 Stratospheric radiative damping increases as atmospheric carbon dioxide concentration rises. We use the one-dimensional mechanistic models of the quasi-biennial oscillation (QBO) to conduct sensitivity experiments and find that the simulated QBO period ...

The Quasi-Biennial Periodicity (QBP) in velocity and intensity helioseismic observations [PDF]
, 2012 We looked for signatures of Quasi-Biennial Periodicity (QBP) over different phases of solar cycle by means of acoustic modes of oscillation. Low-degree p-mode frequencies are shown to be sensitive to changes in magnetic activity due to the global dynamo.

An Analytical Study of Ozone Feedbacks on Kelvin and Rossby–Gravity Waves: Effects on the QBO [PDF]
, 1998 An equatorial beta-plane model of the middle atmosphere is used to analytically examine the effects of radiative cooling and ozone heating on the spatial and temporal evolution of the quasi-biennial oscillation (QBO).

Defining metrics of the Quasi-Biennial Oscillation in global climate models [PDF]
Geoscientific Model Development, 2017 As the dominant mode of variability in the tropical stratosphere, the Quasi-Biennial Oscillation (QBO) has been subject to extensive research. Though there is a well-developed theory of this phenomenon being forced by wave–mean flow interaction ...

An Examination of Anomalously Low Column Ozone in the Southern Hemisphere Midlatitudes During 1997 [PDF]
, 2002 [1] Observations from both ground-based and satellite instruments show record low column ozone abundance between 20°S and 40°S during 1997. The 1997 monthly averaged column ozone from the Total Ozone Mapping Spectrometer (TOMS) is up to 25 Dobson units ...

The Buffer Zone of the Quasi-Biennial Oscillation [PDF]
Journal of the Atmospheric Sciences, 2019 Abstract The quasi-biennial oscillation (QBO) is a descending pattern of winds in the stratosphere that vanishes near the top of the tropical tropopause layer, even though the vertically propagating waves that drive the QBO are thought to originate in the troposphere several kilometers below.
