What results from a temperature inversion known as subsidence inversion?

Cool air rises, leading to cloud formation Sinking air warms, creating stable conditions near the surface Severe storms develop due to high moisture levels Temperature drops uniformly throughout the atmosphere

Correct Answer:

Sinking air warms, creating stable conditions near the surface

Explanation:

In a subsidence inversion, a layer of cooler air is trapped near the surface by a layer of warmer air above it. This occurs when air sinks and compresses, causing it to warm. The warming of the sinking air creates stable atmospheric conditions, preventing vertical mixing of air layers. As a result, the cooler air near the surface remains stagnant, which can lead to the buildup of pollutants and fog, but also contributes to a stable atmosphere where weather changes are minimized. The process is significant in meteorology because it can lead to prolonged calm weather and higher air quality issues when pollutants accumulate in the trapped air.
