The zone where the Maritime Polar airmass meets the Maritime Tropical airmass.

Explanation:

The main airmasses of North America start from the North are the Continental Arctic, Maritime Arctic, Maritime Polar and Maritime Tropical. Continental Polar and Continental Tropical masses do exist but they are either overpowered by a different airmass or simply too small to be considered.

The fronts are as follows, from the North, Arctic Front (between the Continental Arctic and Maritime Arctic masses), Maritime Front (between the Maritime Arctic and Maritime Polar masses) and the Polar front (between the Maritime Polar and Maritime Tropical masses).
