Abstract: It is usually assumed that the circulation anomaly induced directly by the quasi-biennial oscillation (QBO) in the equatorial zonal wind is, approximately, a seasonally independent, two-cell structure symmetric about the ...

Abstract: An interactive stratospheric model was run for 13 years while being forced with the observed daily varying Northern Hemisphere (NH) waves (numbers 1 to 3) on the 368-K isentropic surface (which lies near 150 mb) from 1980 ...

Abstract: The influence of vertical advection on the descent rate of the zero-wind line in both phases of the equatorial quasi-biennial oscillation (QBO) is investigated with the help of the ?THIN AIR? stratosphere two-and-a-half- ...

Abstract: By forcing an interactive chemical?dynamical model of the stratosphere with the observed Singapore zonal winds and with the observed daily varying planetary wave heights just above the tropopause over the period from March ...

Abstract: A two-and-a-half-dimensional interactive stratospheric model (i.e., a zonally averaged dynamical-chemical model combined with a truncated spectral dynamical model), whose equatorial zonal wind was relaxed toward the observed ...
