What is the effect of unstable air on visibility?

Unstable air typically promotes vertical mixing, which can enhance visibility. When air is unstable, it tends to rise and fall in convection currents, allowing for the dispersal of pollutants and moisture. This mixing process helps to clear out haze and other obscurations in the atmosphere, thereby improving visibility. Additionally, unstable conditions are often associated with clear skies and limited low-level moisture, contributing to good visibility.

In contrast, stable air can lead to layers of trapped air and pollutants, resulting in reduced visibility. Thus, the characteristic behavior of unstable air generally leads to good visibility conditions for aviation.
