Divergence (or convergence)is a difficult task to measure with any degree of accuracy using upper-level wind information. Therefore, meteorologists must look for ____, something that can be measured and, at the same time, can be related to regions of diverging (and converging)air.
A)curvature
B)baroclinicity
C)cold advection
D)warm advection
E)vorticity

Vorticity is a measure of the rotation of air parcels and is related to divergence and convergence in the atmosphere. Where there is positive vorticity (cyclonic rotation), air tends to converge at low levels and diverge aloft, and where there is negative vorticity (anticyclonic rotation), the opposite is true. This makes vorticity a useful proxy for identifying areas of divergence and convergence.
