Long‐Term Variations of Jupiter's Stratospheric Planetary Waves Modulated by the Quasi‐Quadrennial Oscillation

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Planetary wave activity on Jupiter has been consistently observed since the Voyager mission. This study uses NASA Infrared Telescope Facility 7.6–7.9 μm long‐term ground‐based observations from 1984 to 2011 and global maps from the Cassini flyby in November and December 2000 to analyze Jupiter's stratospheric planetary wave activity.

The Energy Exascale Earth System Model Version 3: 2. Overview of the Coupled System

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 4, April 2026.
Abstract The Energy Exascale Earth System Model version 3 (E3SMv3) represents the latest advancement in Earth system modeling developed by the U.S. Department of Energy (DOE). Building upon previous versions, E3SMv3 introduces significant updates across its coupled components to enhance capability and improve fidelity.

Improving the Quasi‐Biennial Oscillation via a Surrogate‐Accelerated Multi‐Objective Optimization

Journal of Advances in Modeling Earth Systems
Accurate simulation of the quasi‐biennial oscillation (QBO) is challenging due to uncertainties in representing convectively generated gravity waves.

Quasi-biennial oscillation modulation of stratospheric water vapour in the Asian monsoon [PDF]

Atmospheric Chemistry and Physics
The Asian monsoon (AM) plays a key role in the transport of water vapour to the lower stratosphere and contributes significantly to the wet phase of the annual global stratospheric water vapour cycle.

Sensitivity of the quasi‐biennial oscillation simulated in WACCM to the phase speed spectrum and the settings in an inertial gravity wave parameterization

Journal of Advances in Modeling Earth Systems, 2017
The application of inertial gravity wave parameterization has allowed for the spontaneous generation of quasi‐biennial oscillation (QBO) in the Whole Atmosphere Community Climate Model (WACCM), although there is some mismatch when comparing with ...

A delay differential model of ENSO variability, Part 2: Phase locking, multiple solutions, and dynamics of extrema [PDF]

, 2010
We consider a highly idealized model for El Nino/Southern Oscillation (ENSO) variability, as introduced in an earlier paper. The model is governed by a delay differential equation for sea surface temperature in the Tropical Pacific, and it combines two ...

On the secondary meridional circulation associated with the quasi-biennial oscillation

Tellus B: Chemical and Physical Meteorology, 2002
Concentrations and distributions of stratospheric aerosol, hydrogen fluoride and ozone from the Halogen Occultation Experiment (HALOE) on the Upper Atmosphere Research Satellite (UARS) are used to investigate features associated with transport by the secondary meridional circulation induced by the quasi-biennial oscillation (QBO).

A two-dimensional model of the quasi biennial oscillation of ozone [PDF]

The largest amplitudes of the observed Quasi Biennial Oscillation (QBO) in column ozone are found in high latitudes and this must be taken into account in any explanation of the increased depletion of ozone in the southern polar spring during the 1980's.
