What is atmospheric stagnation and when might it occur?
What will be the ideal response?
ANSWER: Light winds and poor vertical mixing can produce a condition known as atmospheric stagnation. The atmospheric conditions resulting in air stagnation usually occur during particular weather patterns. For example, a region under the domination of a surface high-pressure area or ridge often experiences clear skies, light winds, and a subsidence inversion. Moreover, where warm air rides up over cold surface air, such as ahead of an advancing warm front, stable atmospheric conditions promote the trapping of pollutants near the surface. On the other hand, the strong and gusty winds and generally less-stable air behind a cold front usually results in good dispersion.
