Barotropic Vorticity Equation
The vorticity equation in the absence of horizontal divergence and
vertical motion, so that the absolute
vorticity of a parcel is conserved:
src="equat/33.gif"
width=105src="equat/zetasm.gif"
width=12 is the relative
vorticity and f is the coriolis
parameter.
This equation may also be interpreted as governing vertically averaged
flow in which divergence is present but wind direction is constant with
height. See equivalent
barotropic model.
