A QBO Cookbook: Sensitivity of the Quasi‐Biennial Oscillation to Resolution, Resolved Waves, and Parameterized Gravity Waves [PDF]
Journal of Advances in Modeling Earth Systems, 2022 An intermediate complexity moist general circulation model is used to investigate the sensitivity of the quasi‐biennial oscillation (QBO) to resolution, diffusion, tropical tropospheric waves, and parameterized gravity waves.

Quasi-biennial oscillation: laboratory experiments
Comptes Rendus. PhysiqueThe quasi-biennial oscillation (QBO) is an oscillation of the wind in the equatorial stratosphere. This wind is a mean flow induced by atmospheric waves, including internal gravity waves, which explain that the period (28 month) is not linked to any ...

Is Mesospheric Quasi Biennial Oscillation Ephemeral?
Geophysical Research Letters, 2021 The time evolution of mesospheric quasi biennial oscillation (MQBO) in the 82–98 km altitude region using long‐term meteor radar observations over low and equatorial latitudes and TIMED Doppler Interferometer (TIDI) observations is discussed for the ...

Role of tropical lower stratosphere winds in quasi-biennial oscillation disruptions. [PDF]
Sci Adv, 2022 In 2016, the westerly quasi-biennial oscillation (WQBO) in the equatorial stratosphere was unprecedentedly disrupted by westward forcing near 40 hPa; this was followed by another disruption in 2020.

Crucial role of obliquely propagating gravity waves in the quasi-biennial oscillation dynamics [PDF]
Atmospheric Chemistry and Physics, 2023 In climate modelling, the reality of simulated flows in the middle atmosphere is largely affected by the model's representation of gravity wave processes that are unresolved, while these processes are usually simplified to facilitate computations.

The quasi‐biennial oscillation [PDF]
Reviews of Geophysics, 2001 The quasi‐biennial oscillation (QBO) dominates the variability of the equatorial stratosphere (∼16–50 km) and is easily seen as downward propagating easterly and westerly wind regimes, with a variable period averaging approximately 28 months. From a fluid dynamical perspective, the QBO is a fascinating example of a coherent, oscillating mean flow that ...

Summertime ozone pollution in China affected by stratospheric quasi-biennial oscillation [PDF]
Atmospheric Chemistry and Physics, 2023 In recent years, the near-surface ozone (O3) level has been rising fast in China, with increasing damage to human health and ecosystems. In this study, the impact of stratospheric quasi-biennial oscillation (QBO) on interannual variations in summertime ...

Zonally asymmetric influences of the quasi-biennial oscillation on stratospheric ozone [PDF]
Atmospheric Chemistry and Physics, 2022 The quasi-biennial oscillation (QBO), as the dominant mode in the equatorial stratosphere, modulates the dynamical circulation and the distribution of trace gases in the stratosphere.
