NASA | How to Get Colder Than Anywhere Else

The video explains how clear skies lead to rapid temperature drops as the ground radiates heat into space, chilling the atmosphere. This process results in denser cold air that slides down Antarctica's dome. When this air is trapped and remains stationary, it leads to the lowest temperatures recorded.

What role does stationary air flow play in temperature reduction?

Describe the conditions necessary for achieving the absolute lowest temperatures.
