What is described by the term "smoke inversion"?

The term "smoke inversion" refers to the phenomenon where cooler smoke hangs low to the ground. This occurs when a layer of warm air traps the cooler air, along with any smoke particles, near the surface. Inversions can prevent smoke from rising and dispersing, leading to stagnant air conditions that can exacerbate air quality issues and visibility problems. This scenario is particularly common in valleys or low-lying areas, where temperature differences between layers of air can create significant atmospheric stability. Understanding this concept is essential for firefighters and emergency responders as it affects fire behavior, smoke dispersion patterns, and ultimately, safety considerations during operations.
