What condition is typically present during a temperature inversion?

During a temperature inversion, stable air layers with little wind are a defining characteristic. In this phenomenon, warmer air traps cooler air near the ground, creating a stable condition that inhibits vertical mixing of the atmosphere. This stability leads to limited movement within the air layers, effectively reducing wind and preventing the dispersion of pollutants or other particulates, which can accumulate near the ground.

The other conditions mentioned, such as high winds, dry conditions, and increased rainfall, do not typically coincide with temperature inversions. High winds would disrupt the stability of the inversion by promoting air mixing. Dry conditions may occur, but they are not inherently tied to the dynamics of a temperature inversion; inversions can happen in various moisture conditions. Similarly, increased rainfall is not a feature of inversions, as stable air layers generally suppress precipitation. The correct answer highlights the essential aspect of temperature inversions: the presence of stable air with minimal wind.
