The Quasi-Biennial Oscillation: Impacts, Processes and Projections
Published May 2022
Abstract:
In the tropical stratosphere, deep layers of eastward and westward winds encircle the globe and descend regularly from the upper stratosphere to the tropical tropopause. With a complete cycle typically lasting around two and a half years, this quasi-biennial oscillation (QBO) is arguably the most predictable mode of atmospheric variability that is not linked to the changing seasons. The QBO affects climate phenomena outside the tropical stratosphere including ozone transport, the North Atlantic Oscillation and Madden-Julian Oscillation, and its high predictability could enable better forecasts of them if models can accurately represent the coupling processes. We review progress over the past two decades in understanding and simulating the QBO and its effects on climate. Uncertainties about the waves that force the oscillation, particularly the momentum fluxes
from small-scale gravity waves excited by deep convection, make simulation of the QBO challenging. Improved representation of processes governing the QBO is expected to lead to better forecasts of the QBO and its impacts, increased understanding of unusual events such as the two QBO disruptions observed since 2016, and more reliable future projections of QBO behaviour under climate change.
