    Abstract

    The interaction of horizontal eddy motions and thermal drive in the stratosphere is investigated in equivalent barotropic calculations on the sphere. Eddy advection tends to homogenize the distribution of potential vorticity Q while thermal dissipation drives the motion towards a state of radiative equilibrium. The average circulation is shaped by a balance between these competing influences. Realistic mechanical and thermal forcing lead to time-mean behavior in reasonable agreement with observed monthly mean fields. -from Authors
