Polar front

The polar front is a meteorological term that refers to the boundary between polar air masses and warmer, mid-latitude air masses. This boundary is characterized by a notable temperature gradient and plays a significant role in weather patterns, particularly in the formation of mid-latitude cyclones and storms. Typically situated around 50 to 60 degrees latitude in both hemispheres, the polar front is where cold, dense air from the poles meets the warmer, less dense air from the tropics.
