what are characteristics of unstable air?\nnimbostratus clouds and good surface visibility.\nturbulence and…

Brief Explanations:

Unstable air promotes vertical air movement, which creates turbulence. This vertical motion lifts surface moisture and pollutants, leading to the formation of cumuliform clouds and scattering of particles that reduce surface visibility. Nimbostratus clouds are associated with stable air, and unstable air does not result in good visibility.

Answer:

Turbulence and poor surface visibility.
