Kawasan kutub menerima sinaran suria kurang sengit daripada bahagian-bahagian lain bumi kerana tenaga matahari tiba pada sudut serong, merebak di kawasan yang lebih besar, dan juga bergerak jarak jauh melalui atmosfera bumi di mana ia dapat diserap, tersebar atau terpantul, yang merupakan perkara yang sama yang menyebabkan musim sejuk menjadi lebih sejuk berbanding dengan tahun-tahun yang lain di kawasan yang sederhana.
Polar regions receive less intense solar radiation than the other parts of Earth because the sun's energy arrives at an oblique angle, spreading over a larger area, and also travels a longer distance through the Earth's atmosphere in which it may be absorbed, scattered or reflected, which is the same thing that causes winters to be colder than the rest of the year in temperate areas.
 
The [[Kecondongan paksi|axial tilt]] of the Earth has a major effect on climate of the polar regions. Since the polar regions are the farthest from the [[Khatulistiwa|equator]], they receive the least amount of sunlight and are therefore frigid. The large amount of ice and snow also reflects a large part of what little sunlight the Polar regions receive, contributing to the cold. Polar regions are characterized by the [[Iklim kutub|polar climate]], extremely cold temperatures, heavy [[Tempoh glasier|glaciation]] wherever there is sufficient [[Kerpasan|precipitation]] to form permanent ice, and extreme variations in daylight hours, with twenty-four hours of daylight in summer, and complete darkness at [[Musim sejuk|mid-winter]].
