What storm feature is associated with supercell thunderstorms?

Supercell thunderstorms are characterized by their rotating updrafts, known as mesocyclones, and they often produce severe weather phenomena, including tornadoes, large hail, and heavy rain. The correct response highlights that supercells typically form as isolated storms rather than as clusters. This means they usually develop independently rather than being part of a larger group of thunderstorms, which distinguishes them from other types of storms that may occur in clusters or squall lines.

The feature associated with supercells is their ability to sustain intense and organized convection, leading to severe weather. Unlike mere clusters or lines of thunderstorms, supercells can exhibit a well-defined structure due to their dynamic characteristics. Other options, such as strong gust fronts and squall lines, are indicators of different storm systems, whereas frequent light rain does not signify the severe and violent nature typically associated with supercell thunderstorms.
