When do atmospheric inversion conditions typically occur?

Atmospheric inversion conditions typically occur when the wind is calm and the ground temperature is lower than the air above. In this scenario, a layer of warmer air traps cooler air near the surface. This setup is significant because it can limit air mixing and lead to the accumulation of pollutants or pesticides in the lower atmosphere, creating potential health and environmental hazards.

This phenomenon often occurs at night or early morning when the ground cools down after sunset, leading to the temperature inversion. Understanding this condition is crucial for pesticide application since it can influence drift and the overall effectiveness of the pesticide used. Being aware of inversion conditions helps ensure safer and more effective agricultural practices.
