The movement or transfer of vorticity helps in the assessment of vertical motion of air (ascent) in the troposphere. Where a local vorticity maximum approaches an area there is a tendency for air to rise and where a local vorticity maximum moves ...

Vorticity is the tendency of an air particle to rotate or circulate around a particular point. Relative Vorticity is a measure about a vertical axis of the local rotation or spin of the air relative...
