In meteorology, the polar front is the boundary between the polar cell and the Ferrel cell in each hemisphere. At this boundary a sharp gradient in temperature occurs between these two air masses, each at very different temperatures. The polar front arises as a result of cold polar air meeting warm tropical air. Polar Front Jet Stream The wind system of the Earth’s troposphere exists because of the unequal intensity of solar radiation (because of Earth’s curved surface) and direction to the rotation of the Earth. Coriolis deflects winds to the right in Northern Hemisphere and to the left in the southern Hemisphere.

Air masses can extend thousands of kilometers across the surface of the Earth, and can reach from ground level to the stratosphere—16 kilometers (10 miles) into the atmosphere.
