A mixing layer is characterized by
A) enhanced vertical air motions.
B) suppressed vertical air motions.
C) strong horizontal winds.
D) high concentrations of pollutants.

Question

Quizplus · Accepted Answer

A mixing layer is characterized by enhanced vertical air motions, which promote mixing of air masses with different characteristics such as temperature and humidity. This mixing can result in changes in atmospheric stability, turbulence, and dispersion of pollutants. Therefore, the mixing layer is an important component of the planetary boundary layer and has significant impacts on air quality, weather, and climate. The other options (B, C, D) do not accurately describe the characteristics of a mixing layer.
