How do showery precipitation and intermittent precipitation differ?

Showery precipitation is characterized by its variability in intensity, often changing quickly from light to heavy, and is typically associated with cumulus cloud formation. These clouds tend to develop and dissipate under unstable atmospheric conditions, leading to the rapid onset and cessation of precipitation. This results in the distinct "showery" pattern where rain may be falling heavily in one area while nearby locations remain dry.

On the other hand, intermittent precipitation is generally more stable and does not exhibit the same rapid fluctuations in intensity. Intermittent rain can occur over a longer period, sometimes in light, consistent amounts, and is not necessarily tied to the same cloud dynamics. It often represents a steadier form of precipitation that occurs irregularly but can last longer than showers.

The other choices contrast elements of consistency, occurrence during storms, or suggest that both types of precipitation share identical characteristics, which is not accurate. The key distinguishing factor is the intensity and cloud association of showers versus the more stable nature of intermittent precipitation.
