Polar cyclones (also known as Arctic Cyclones) are vast areas of low pressure. They should not be confused with what are commonly referred to as polar lows that behave similarly to hurricanes. Radar image of a tropical cyclone in the northern hemisphere. ... Polar lows are similar in behavior and size to tropical cyclones, although generally much shorter lived. ...
A polar cyclone is a low pressure weather system usually spanning 1,000–2,000 kilometers in which the air is circulating in a counterclockwise fashion (in the northern hemisphere). The reason for the rotation is the same as tropical cyclones, the Coriolis effect.

Cyclone activity is most prevalent in the Eurasian Arctic with approximately 15 cyclones per winter. Polar cyclones also occur in Greenland and the Canadian arctic.
Polar cyclones can occur at any time during the year. However, summer cyclones tend to be weaker than winter cyclones. They are not well studied and seldom destructive as they typically take place in sparsely populated areas.

Extratropical cyclones lie somewhere in between tropical cyclones and mid-latitude cyclones, drawing a portion of their energy through the evaporation and condensation of ocean water, and some through horizontal temperature gradients in the atmosphere. ...
