A QBO Cookbook: Sensitivity of the Quasi-Biennial Oscillation to Resolution, Resolved Waves, and Parameterized Gravity Waves. [PDF]

J Adv Model Earth Syst, 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.

The disappearing quasi-biennial oscillation under sustained global warming. [PDF]

Nat Commun
The stratospheric quasi-biennial oscillation (QBO) is a key modulator of interannual variability in global weather and climate. Over recent decades, the amplitude of the lower-stratospheric QBO has weakened, and in recent years the QBO has experienced ...

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 ...

Surface impacts of the Quasi Biennial Oscillation [PDF]

Atmospheric Chemistry and Physics, 2018
Teleconnections between the Quasi Biennial Oscillation (QBO) and the Northern Hemisphere zonally averaged zonal winds, mean sea level pressure (mslp) and tropical precipitation are explored.

Response of the Quasi‐Biennial Oscillation to Historical Volcanic Eruptions

Geophysical Research Letters, 2021
The impact of volcanic eruptions on surface climate is well‐appreciated, but their in situ impact on the Quasi‐Biennial Oscillation (QBO) has received comparatively little attention.

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.

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 ...

Subseasonal midlatitude prediction skill following Quasi-Biennial Oscillation and Madden–Julian Oscillation activity [PDF]

Weather and Climate Dynamics, 2020
The Madden–Julian Oscillation (MJO) is known to force extratropical weather days to weeks following an MJO event through excitation of stationary Rossby waves, also referred to as tropical–extratropical teleconnections.

Quasi-biennial oscillation of the tropical stratospheric aerosol layer [PDF]

Atmospheric Chemistry and Physics, 2015
This study describes how aerosol in an aerosol-coupled climate model of the middle atmosphere is influenced by the quasi-biennial oscillation (QBO) during times when the stratosphere is largely unperturbed by volcanic material.
