What atmospheric condition is often indicated by dust devils?

Dust devils are a phenomenon that typically forms when the atmosphere is unstable. This instability occurs when warmer air rises rapidly in a local area, often resulting in the rotation and formation of a small whirlwind. The presence of dust devils indicates that the surface air is significantly heated, creating a strong upward draft that pulls in cooler air from the surrounding area.

In wildland fire behavior, unstable air can enhance fire activity and spread because the rising hot air can carry embers and flames higher into the atmosphere, potentially leading to increased fire intensity and erratic fire behavior. Understanding these atmospheric conditions is crucial for predicting fire behavior and ensuring safety during fire incidents.
