The Quasi-biennial Oscillation and annual variations in tropical ozone from SHADOZ and HALOE
We examine the tropical ozone mixing ratio perturbation fields generated from a monthly ozone climatology using 1998 to 2006 ozonesonde data from the Southern Hemisphere Additional Ozonesondes (SHADOZ) network and the 13-year satellite record from 1993 to 2005 obtained from the Halogen Occultation Experiment (HALOE). The long time series and high vertical resolution of the ozone and temperature...
متن کاملKinetic Energy and Quasi-biennial Oscillation
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 cnergy, the horizontal momentum and heat transports a t “low” latitudes, and the tropical zonal wind and temperature for the lower stratosphere. It is deduced that the variation of the vertical flux of geopotential is in phase wit...
متن کاملNote concerning the Period of the Quasi-biennial Oscillation
The period of the quasi-biennial oscillation is examined through the use of a harmonic procedure which allows one to examine periods of interest without omission of any data. On the basis of 8, and 5th years, of mean-monthly zonal-wind and temperature data in the Northern and Southern Hemispheres, respectively, it is found that: (1) A quasi-biennial oscillation in zonal-wind exists in the tropo...
متن کاملVariation with Longitude of the Quasi-biennial Oscillation
Daily data at 16 stations along five latitudes from 13"N. to 33"s. were carefully examined a t the 50-, lo&, and 500-mb. levels for evidence of longitudinal phase progression of the quasi-biennial oscillation (&BO). At 50 mb. there is evidence of west to east progression although there are many irregularities and much uncertainty. The phase dates differ by days a t low latitudes. At 100 and 500...
متن کاملThe Influence of Wave– and Zonal Mean–Ozone Feedbacks on the Quasi-biennial Oscillation
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 zonal mean and (linear) wave fields of ozone, temperature, and wind, and is driven by specifying the amplitudes of a Kelvin wave and a Rossby–...
