B) anticyclonic descent of air
C) instability
D) relatively few condensation nuclei
E) atmospheric equilibrium

Question

Quizplus · Accepted Answer

Showery weather and cumuliform clouds are indicative of instability in the atmosphere, which means that warm, moist air is rising rapidly and creating clouds and precipitation. This is in contrast to anticyclonic conditions, which are associated with stable, sinking air and clear skies. Orographic lift and condensation nuclei can also contribute to cloud formation and precipitation, but they are not as closely linked to showery weather and cumuliform clouds as instability is. Atmospheric equilibrium is a general state in which all forces and factors in the atmosphere are roughly balanced, but it does not necessarily lead to any specific weather conditions.
