The Movement of Air Masses
transporting warm air northward and colder air southward

Counterclockwise winds associated with cyclones transport heat and moisture from lower to higher latitudes and play a significant role in the movement of air masses.

As a cyclone intensifies, (the central pressure drops), counterclockwise winds around the low pressure center also intensify, transporting the air masses around the center of circulation.
