Diurnal Cycle of Tropospheric Winds over West Sumatra and Its Variability Associated with Various Climate and Weather Modes

open access: yesAtmosphere, 2023
The typical diurnal variability of tropospheric winds over West Sumatra and their changes associated with El Niño Southern Oscillation, Quasi-Biennial Oscillation, Madden–Julian Oscillations and convectively coupled Kelvin waves during the extended ...

The tropical route of quasi-biennial oscillation (QBO) teleconnections in a climate model [PDF]

open access: yesWeather 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.

A New Pathway for Communicating the 11-year Solar Cycle Signal to the QBO [PDF]

open access: yes, 2005
[1] The response of the equatorial quasi-biennial oscillation (QBO) to zonal-mean ozone perturbations consistent with the 11-year solar cycle is examined using a 2 1/2 dimensional model of the tropical stratosphere.

Explaining the period fluctuation of the quasi-biennial oscillation [PDF]

open access: yesAtmospheric Chemistry and Physics
The tropical stratosphere is characterized by a periodic oscillation of wind direction between westerly and easterly, known as the quasi-biennial oscillation (QBO), which modulates middle atmospheric circulations and surface climate on interannual ...

The impact of increasing stratospheric radiative damping on the quasi-biennial oscillation period [PDF]

open access: yesAtmospheric 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 Influence of Wave– and Zonal Mean–Ozone Feedbacks on the Quasi-biennial Oscillation [PDF]

open access: yes, 2000
The effects of wave and zonal mean ozone heating on the evolution of the quasi-biennial oscillation (QBO) are examined using a two-dimensional mechanistic model of the equatorial stratosphere. The model atmosphere is governed by coupled equations for the

A thorough analysis of the short- and mid-term activity-related variations in the solar acoustic frequencies [PDF]

open access: yes, 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.

Defining metrics of the Quasi-Biennial Oscillation in global climate models [PDF]

open access: yesGeoscientific 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 ...

Quasi-biennial oscillation of the ionospheric wind dynamo [PDF]

open access: yes, 2017
The interannual variation of the ionospheric solar quiet (Sq) current system is examined. A dense magnetometer network over Japan enables the accurate determination of the central position of the northern Sq current loop or the Sq current focus, during ...

Impacts of Quasi-Biennial Oscillation and El Niño–Southern Oscillation on Stratospheric Isentropic Mixing Process

open access: yesRemote Sensing, 2023
The present study investigates the influences of stratospheric quasi-biennial oscillation (QBO) and El Niño–Southern Oscillation (ENSO) on the intensity of stratospheric isentropic mixing based on ERA-Interim and MERRA-2 reanalysis products.
