Vorticity and
Rossby Wave
q Rossby waves are produced from the conservation of absolute vorticity.
q As an air parcle moves northward or southward over different latitudes, it experiences changes in Earth (planetary) vorticity.
qIn order to conserve
the absolute vorticity, the air has
to rotate to produce relative
vorticity.
q The rotation due to the relative vorticity bring the air back to where it was.
