In terms of weather, stable air is most likely to lead to which type of visibility?

  1. Clear visibility

  2. Poor visibility

  3. Variable visibility

  4. Good visibility

The correct answer is: Poor visibility

Stable air is characterized by a lack of vertical movement, which can lead to the accumulation of pollutants and moisture near the surface, contributing to reduced visibility. In stable conditions, the atmosphere tends to trap air and associated contaminants, such as fog, haze, or mist, which can obscure visibility. This occurs because there is minimal mixing of the air layers, preventing the dispersal of these particles. As a result, the likelihood of experiencing poor visibility increases in stable air conditions compared to unstable air, which typically promotes better overall visibility through increased mixing and vertical air movement.
