Dynamical and Trace Gas Responses of the Quasi‐Biennial Oscillation to Increased CO2
Journal of Geophysical Research: Atmospheres, 2021Long‐term projections of the Quasi‐Biennial Oscillation (QBO) remain uncertain. Using the high‐top “Middle Atmosphere” (MA) version of the NASA Goddard Institute for Space Studies (GISS) ModelE (E2.2‐AP), we show that increased CO2 reduces the QBO period

The impact of the quasi‐biennial oscillation (QBO) on the surface air temperature (SAT) in the Northern Hemisphere extratropics is investigated. It is found that the QBO, defined as 70‐hPa zonal wind in the deep tropics, is negatively correlated with the

The role of chemical processes in the quasi-biennial oscillation (QBO) signal in stratospheric ozone
, 2021The stratospheric quasi-biennial oscillation (QBO) is known to cause variations in the transport of chemical tracers but the role of chemical processes in modulating their QBO signals remains unclear.

Development of the Extratropical Response to the Stratospheric Quasi-Biennial Oscillation
, 2021Using the Model of an Idealized Moist Atmosphere (MiMA) capable of spontaneously generating a Quasi-Biennial Oscillation (QBO), the gradual establishment of the extratropical response to the QBO is explored.

Journal of Climate, 2020
Using 17 CMIP5 and CMIP6 models with a spontaneously generated quasi-biennial oscillation (QBO)-like phenomenon, this study explores and evaluates three dynamical pathways for impacts of the QBO on the troposphere: 1) the Holtan–Tan (HT) effect on the ...

Quasi-Biennial Oscillations in Tropospheric Energy
Monthly Weather Review, 1974Abstract Evidence is presented for an approximate year-to-year variation of the zonal available potential (AZ), eddy available potential (AE), zonal kinetic (KZ) and eddy kinetic energy (KE) in the extra-tropical troposphere between 1962 and 1971. A modification of the oscillations occurs after 1968 due to as yet undetermined causes, but prior to this ...

The Quasi-Biennial Oscillation (QBO)
1999Clayton was the first to note that the precipitation and pressure at several stations in the United States contained an approximately two-year oscillation. His stations were located all over the country, most were from the period 1874–1883, but there were some among them going as far hack as 1839 (Clayton 1884, 1885). Clayton’s oscillation had a period

Atmospheric Quasi-Biennial Oscillations
Monthly Weather Review, 1980Abstract A detailed analysis has been made of a quasi-biennial oscillation (QBO) in the tropospheric ultralong waves of the Southern Hemisphere and interrelationships with the QBO in zonal mean westerly winds of the equatorial stratosphere. In spite of the fact that highly significant spectral peaks at a period close to 26 months occur in both ...

Simulated disruptions of the Quasi-Biennial Oscillation
2021<p>The Quasi-Biennial Oscillation has exhibited remarkable stability over the observational record&#8212;until a well-documented 2015/16 disruption and an emerging disruption in 2020/21. The possibility that disruptions are more frequent in a changing climate is important to consider, as the QBO affects predictability ...
