Based on dynamical analysis of data both from conventional and special observations in the Scientific Experiment over the Plateau made in 1979,with turbulent viscous stress and atmospheric stratification considered and by using a two-dimensional model designed to describe the passage of the westerlies over the Plateau on a zonal cross-section, a simulation ismade of the formation of zonal vortices in the Plateau boundary layerand their eastward movement out of the prominence as well as the variations of the zonal circulation caused thereby, etc.
