* Polar Regions are Cold: The poles receive less solar radiation than the equator, resulting in consistently cold temperatures.
* Air Temperature and Density: Cold air is denser than warm air. This means that the air near the poles is cold and dense.
* Formation of Polar Air Masses: As a result, air masses that form near the poles are characterized by their cold, dry, and stable nature.
