Which climate type corresponds with polar conditions?

Climate Type E corresponds with polar conditions, characterized by extremely cold temperatures for the majority of the year, with little to no vegetation. The defining features of this climate type include very low average temperatures, especially in winter, where temperatures rarely rise above freezing, and in some areas, even summer temperatures can remain quite cool.

In polar climates, precipitation is minimal, often resulting in arid conditions similar to a desert, but with the key distinction being the cold temperatures that dominate both in summer and winter. Ice sheets and permafrost are common, and the biodiversity is limited primarily to species adapted to extreme cold, such as polar bears, seals, and certain hardy plant species.

The other climate types listed do not fit the polar conditions: A generally refers to tropical climates, C typically describes temperate climates, and D is classified as a continental climate with more significant seasonal temperature variation, which is not characteristic of polar regions.
