What characterizes a derecho in meteorology?

A derecho in meteorology is characterized by a complex of thunderstorms that are capable of producing widespread wind damage over a long distance, typically exceeding 240 miles. This phenomenon involves a series of storms organized into a bow shape and is associated with a powerful wind event resulting from the downdrafts of the thunderstorms.

The sustained winds and rapid movement of the storm complex are key features that distinguish a derecho from other weather phenomena. The term itself denotes the possibility of damaging winds that can exceed straight-line wind gusts, which may lead to significant destruction along its path. Thus, it accurately describes the long-distance nature and intense wind activity characteristic of such weather events.

Other types of storms or weather phenomena do not have the extensive wind impact and distance that a derecho entails, making the correct choice distinctly applicable to this specific meteorological event.
