Effect of the Quasi‐Biennial Oscillation on Carbon Monoxide in the Stratosphere

Earth and Space Science, 2019
The interannual variability of tropical carbon monoxide from the Microwave Limb Sounder over 2004–2018 period is dominated by the quasi‐biennial oscillation (QBO).

The stratospheric quasi-biennial oscillation observed in the semidiurnal ground pressure data [PDF]

Annales Geophysicae, 1995
Ground pressure observations made at Macao (22°N, 113°E) from 1953 to 1991 are analyzed and compared with the stratospheric quasi-biennial oscillation (QBO) data obtained during the same interval.

The role of the basic state in the ENSO-monsoon relationship and implications for predictability [PDF]

, 2005
The impact of systematic model errors on a coupled simulation of the Asian Summer monsoon and its interannual variability is studied. Although the mean monsoon climate is reasonably well captured, systematic errors in the equatorial Pacific mean that the

Maintenance of Moisture Anomalies Across Synoptic and Intraseasonal Timescales Over the Indo‐Pacific Warm Pool

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Moisture variability plays a fundamental role in regulating tropical precipitation; however, the mechanisms that sustain moisture anomalies across different timescales remain unclear. This study examines how moisture anomalies are regulated over the Indo‐Pacific warm pool using the column‐integrated moist static energy (CMSE) budget.

Role of the quasi-biennial oscillation in alleviating biases in the semi-annual oscillation [PDF]

Weather and Climate Dynamics
Model representations of the stratospheric semi-annual oscillation (SAO) show a common easterly bias, with a weaker westerly phase and stronger easterly phase compared to observations.

Quasi-Biennial Oscillation and Sudden Stratospheric Warmings during the Last Glacial Maximum

Atmosphere, 2020
The quasi-biennial oscillation (QBO) and sudden stratospheric warmings (SSWs) during the Last Glacial Maximum (LGM) are investigated in simulations using the Whole Atmosphere Community Climate Model version 6 (WACCM6).

Initial Atmospheric Waves Experiment (AWE) Imaging Analyses: Gravity Wave Sources, Temperatures, Pseudomomentum Fluxes, and Horizontal Wavenumber Spectra at the OH Layer

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract The NASA Atmospheric Waves Experiment (AWE) employs an OH imager that began measurements aboard the International Space Station (ISS) on 22 November 2023. The motivation for AWE was to quantify gravity wave (GW) responses to diverse sources and their influences extending into the mesosphere and higher altitudes.

A Puzzling Quasi‐Periodic Variability in the Tropical Middle Atmosphere

Geophysical Research Letters
The Quasi‐Biennial Oscillation and the Semiannual Oscillation have been identified to be the leading modes of variability in the tropical middle atmosphere.

Successes and Failures of Current AI Climate Models

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract AI climate model simulations are in their infancy and the paper by Baxter et al. (this issue) reports the results of a new set of tests for how well AI weather and climate models represent aspects of atmospheric dynamics, including low frequency variability.

Cross-scale causal information flow from the El Niño–Southern Oscillation to precipitation in eastern China [PDF]

Earth System Dynamics
The El Niño–Southern Oscillation (ENSO) is a dominant mode of climate variability influencing temperature and precipitation in distant parts of the world. Traditionally, the ENSO influence is assessed considering its amplitude.
