Why do polar climates invaribly exhibit low precipitation values?

Polar climates invariably exhibit low precipitation values because there is no humidity in those areas.

Explanation:

The polar climate is characterized by having almost permanently temperatures below 0 ° C; and little rainfall. The humidity in the air is non-existent and the wind is usually quite intense, which makes living conditions in this climate very bad.

The polar climate occurs mainly in the two poles, reaching more severe conditions in Antarctica, since being a continent, temperatures are cooler than those of the North Pole, reaching -70, -80 and even -89.5 ° C (record on the Earth's surface). The climate of the highest areas of the main mountain ranges of the planet closely resemble the polar, being able to occur on the summits of the Himalayas, the Andes or the mountains of Alaska.
