Overview
High latitude climates, comprising the Köppen Group E (Polar) and high-latitude Group D (Severe Midlatitude / Subarctic) classifications, are found poleward of 60° latitude in both hemispheres. These regions are characterized by a profound deficit in solar radiation due to low sun angles and extreme variations in day length, including periods of continuous darkness in winter and continuous daylight in summer.
These environments are dominated by cold, dense polar and arctic air masses that suppress moisture, making high-latitude zones some of the driest yet most cold-stressed regions on Earth. Moving from the subarctic boundaries to the extreme poles, these climates transition from the massive temperature swings of the continental Subarctic climate to the permanently frozen soils of the Tundra, and finally to the perpetual ice sheets of the Ice Cap Climate.
