(climatology)
The climate of a geographical polar region, most commonly taken to be a climate which is too cold to support the growth of trees. Also known as arctic climate; snow climate.

Polar Climate

 

a climate of “eternal frost,” with temperatures rarely exceeding 0° C even in summer and with little precipitation (100–200 mm per year). Polar climate is typical of snow- and ice-covered regions of the Arctic Ocean and its is lands, Greenland, and Antarctica. Its mildest form occurs in the Atlantic section of the arctic, and its most severe form on the plateau of Eastern Antarctica.
