Relative Vorticity

  • produced by two effects:
    • curvature
    • shear
  • The sum of a parcel's planetary vorticity and its relative vorticity is called absolute vorticity


Suppose that the earth stops rotating.  How would this affect the earth's vorticity?  What would happen to the absolute vorticity of a moving air parcel?  If the parcel were initially moving southwestward, how would its direction change, if at all?
