What term describes precipitation and wind produced by the meeting of two air masses associated with an extratropical cyclone, typically with one air mass sliding over or under the other?

When two contrasting air masses meet, a front forms at their boundary in mid-latitude storms. The interaction, especially when one mass slides over or under the other (overrunning), lifts moist air and drives the development of clouds, rain, and stronger winds around the extratropical cyclone. The term that captures the precipitation and winds produced by this encounter is a frontal storm, reflecting the role of the front in directing the storm’s weather. In contrast, a hurricane is a tropical, warm-core system not driven by frontal boundaries, and the Intertropical Convergence Zone is an equatorial region of convection—not the mid-latitude front-driven phenomenon described here.
