Kinetic 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 کاملLength-of-Day Variations Caused by El Nino-Southern Oscillation and Quasi-Biennial Oscillation.
Two prominent interannual atmospheric fluctuations, the El Niño-Southern Oscillation in the troposphere-ocean system and the Quasi-Biennial Oscillation in the equatorial stratosphere, account for most of the observed interannual length-of-day (LOD) variation from 1964 through 1987, with a relative contribution of about 2 to 1. Thus the atmosphere-LOD connection extends from seasonal and shorter...
متن کاملArctic oscillation response to the 1991 Pinatubo eruption in the SKYHI general circulation model with a realistic quasi-biennial oscillation
[1] Stratospheric aerosol clouds from large tropical volcanic eruptions can be expected to alter the atmospheric radiative balance for a period of up to several years. Observations following several previous major eruptions suggest that one effect of the radiative perturbations is to cause anomalies in the Northern Hemisphere extratropical winter tropospheric circulation that can be broadly cha...
