Cold air holds less moisture than temperate air. This is because the molecules of air are packed so tightly that it’s as if the moisture has been squeezed out of it. This means that the air in Antarctica is very dry. Relative humidities in the interior average less one tenth of one percent! Most visitors to Antarctica pack a few extra bottles of moisturizer before setting foot on the continent!
