The polar front is the boundary between…

  • A
    arctic air and polar air.
  • B
    polar air and tropical air.
  • C
    arctic air and tropical air.
  • D
    maritime polar air and continental polar air.

Refer to figure.

The polar front is the junction/boundary between the Ferrell (tropical air mass) and Polar cells (polar air mass). At this low-pressure zone, relatively warm, moist air of the Ferrel Cell runs into relatively cold, dry air of the Polar cell.
In the Northern hemisphere:

  • Warm air mass (Tropical airmass) => South
  • Cold air mass (Polar air mass) => North
Note:The Arctic Front is the boundary between the Arctic and the Polar air masses.
The Mediterranean Front is the boundary between Polar Continental or Maritime air from
Europe and Tropical Continental air from North Africa (disappears in summer).
