What term describes precipitation characterized by rapid intensity changes?

The term that describes precipitation characterized by rapid intensity changes is "showers." Showers are defined by their intermittent nature, where there can be brief periods of heavy rain followed by relative dryness. This variability in intensity is a hallmark of showers, which can quickly escalate or diminish.

In contrast, a thunderstorm refers to a weather event that includes thunder and lightning and typically produces more prolonged precipitation rather than the quick transitions seen in showers. Blowing typically refers to a condition involving wind affecting visibility, often during precipitation or snow conditions, but does not itself refer to the variation in precipitation intensity. Squalls are sudden and brief bursts of wind or precipitation, but they do not specifically emphasize the rapid changes in precipitation intensity in the same way that showers do.
