KINETIC ENERGY AND QUASI-BIENNIAL OSCILLATION

Monthly Weather Review, 1971
The modulation of the vertical flux of kinetic energy to the stratosphere by the pressure-work effect at 100 mb is compared with variations in the hemispheric kinetic energy, the horizontal momentum and heat transports at 'low' latitudes, and the tropical zonal wind and temperature for the lower stratosphere.

A Theory of the Quasi-Biennial Oscillation

Journal of the Atmospheric Sciences, 1968
Abstract A theory is presented which indicates that the quasi-biennial oscillation of the zonal wind in the tropical stratosphere is a result of the interaction of long-period, vertically propagating gravity waves with the zonal wind. We discuss the theoretical basis and observational evidence for the existence of long-period gravity waves near the ...

Quasi-Biennial Oscillation in Ozone

Journal of the Atmospheric Sciences, 1967
Abstract Harmonic analyses of mean monthly ozone data, after the annual cycle has been removed, have shown the existence of the quasi-biennial oscillation with a period of about 26 months. It extends from the equator to the temperate and polar latitudes in the Northern Hemisphere.

Seasonal Variation of the Quasi‐Biennial Oscillation Descent

Journal of Geophysical Research: Atmospheres, 2020
AbstractThis study examines variations through the year in the rate of descent of the quasi‐biennial oscillation (QBO) wind in the tropical lower stratosphere. The work is based on the Modern‐Era Retrospective analysis for Research and Applications, Version 2 (MERRA‐2) multiyear global reanalysis.

Projected Strengthening of the Extratropical Surface Impacts of the Stratospheric Quasi‐Biennial Oscillation

Geophysical Research Letters, 2020
Using state‐of‐the‐art models with a spontaneous quasi‐biennial oscillation (QBO) from the Coupled Model Intercomparison Project Phases 5 and 6 (CMIP5/6), this study explores projected changes in the Holton‐Tan (HT) relationship and the near‐surface ...

Independent and joint influences of eastern Pacific El Niño–southern oscillation and quasi‐biennial oscillation on Northern Hemispheric stratospheric ozone

International Journal of Climatology, 2020
Using ozone observations, reanalysis data, and climate model simulations, this study investigates in detail the independent and joint influences of the eastern Pacific (EP) El Niño–Southern Oscillation (ENSO) and the quasi‐biennial oscillation (QBO) on ...

The latitudinal structure of the quasi‐biennial oscillation

Quarterly Journal of the Royal Meteorological Society, 1998
AbstractThe theory of symmetric time‐dependent meridional circulations in a radiatively damped atmosphere shows that, when the frequency σ of the time variation of an applied body force is smaller than the radiative damping rate α, there are two distinct forms of response to the force. At high latitudes, the response appears primarily as a quasi‐steady

Trade-wind variability, southern oscillation and quasi-biennial oscillation

Archiv für Meteorologie, Geophysik und Bioklimatologie Serie A, 1979
Thev-components of the trade-wind systems in the North and South Pacific and Atlantic Oceans undergo surges of above- and below-normal convergence. These surges have a typical time scale of the order of a year and coincide with long-term fluctuations of precipitation in the inter-tropical convergence zone (ITCZ). There is now evidence that these surges

Interaction of the quasi‐biennial oscillation and stratopause semiannual oscillation

Journal of Geophysical Research: Atmospheres, 1997
Analysis of rawinsonde and rocketsonde data at Ascension Island (7.6°S, 14.4°W) and Kwajalein (8.7°N, 167°E) in 1962–1991 suggests that the quasi‐biennial oscillation (QBO) in the middle stratosphere is synchronized with the seasonal cycle and that descending westerly phases of the stratopause semiannual oscillation (SAO) are strongly influenced by the

On quasi–biennial oscillation in air–sea system

Advances in Atmospheric Sciences, 1991
From the COADS (Comprehensive Ocean–Atmosphere Data Set) I and the COADS II, we got a monthly data set of sea surface temperature (SST), zonal and meridional wind components at sea level (U,V) and sea level pressure (SLP) with 4° × 4° grid system covering the period from Jan. 1950 to Dec.
