Question

Quizplus · Accepted Answer

The polar regions are characterized by cold temperatures, and cold air can hold less moisture than warm air. As a result, the air in polar regions is typically very dry, but when there is some moisture present, it can quickly reach saturation due to the low capacity for moisture in the cold air. Therefore, the relative humidity in polar regions can often be near 100 percent.
