The variability of the mean flow of the equatorial middle                  atmosphere (15 to 90 km altitude) is dominated by the quasi-                    biennial and semi-annual oscillations (the QBO and SAO,                         respectively).  The oscillations are manifested as a westerly                   phase of the equatorial zonal winds and represent a condition                   of superrotation in terms of angular momentum.  The purpose of                  this research is to explore, from a theoretical viewpoint, the                  dynamics of these oscillations.  The QBO is a stratospheric                     phenomenon, occurring irregularly every 22 to 34 months,                        whereas the SAO is semiannual and has components in both the                    mesosphere and stratosphere.                                                         Atmospheric motion in the middle atmosphere is influenced                  by radiative and photochemical processes.  Dr. Dunkerton, in                    collaboration with scientists from the United kingdom, will                     further investigate the QBO and SAO using a fully coupled two-                  dimensional radiative-dynamical-photochemical model.
