An Arctic cyclone is a polar low with a hurricane-like structure. Arctic Cyclones receive names when they receive winds of 39 mph, just like tropical cyclones. They are considered "Arctic Cyclones" with hurricane-force winds. Stronger Arctic Cyclones can produce blizzard conditions, whiteouts, and very strong winds. Because they are most likely to form around Christmas, a Christmas-themed name list is used.

North Polar Cyclones are most common to form in two concentrated areas: the Baffin Bay and the Arctic Ocean. Most strong Polar Cyclones originate from Polar Waves that move off the coast of Canada or Iceland. Rapid deepening for polar cyclones most commonly occurs in the Baffin Bay when wind shear is low. Most landfalling polar cyclones originate in the Baffin Bay. Polar cyclones most commonly move northwestward due to the Polar Easterly winds. There have been exceptions to this, such as the pre-season Polar Cyclone Angel in 2015. During the early part of the season, most polar storms form north of Canada, while in the heart of the season in December, most storms form north of Iceland. Since the waters freeze late in the season, most storms form in the Eurasian side of the world instead of the American side. The season is defined from November 1 (the day after Halloween) to January 7 (Orthodox Christian Christmas). Storms have also formed in October and February as well, and even once in September and in March.
In rare cases, ex-tropical cyclones in the Atlantic keep moving northward into the North Pole basin. However, it is exceptionally rare for tropical cyclones to reach the north pole before completely dissipating. In this case, storms keep their original name unless the storm dissipates before entering the basin.
Two naming lists are used: The names are all Christmas-themed and rotate from year to year. Name lists are used from July 1 of the initial year to June 30 of the following year.
