When does an inversion occur?

An inversion occurs when the surface air is cooler than the air above it. This situation is characterized by a temperature gradient that is the opposite of the normal atmospheric condition. In a standard atmosphere, air temperature typically decreases with altitude; however, during an inversion, a layer of warmer air traps the cooler air beneath it. This phenomenon can impact various environmental factors, such as air quality and weather patterns, because the cooler air at the surface can become stagnant and lead to the accumulation of pollutants.

Inversions often happen under certain weather conditions, typically during the night when the ground loses heat more quickly than the air above, leading to cooler air near the surface. This understanding of temperature inversions is crucial for pest control applicators, as these conditions can influence pest behavior and the effectiveness of certain treatments.
