Hook echo - Wikipedia
A hook echo is a pendant or hook-shaped weather radar signature as part of some supercell thunderstorms. It is found in the lower portions of a storm as air and precipitation flow into a mesocyclone, resulting in a curved feature of reflectivity. The echo is produced by rain, hail, or debris being wrapped around the supercell. [1]

Feb 14, 2013 · The Hook Echo. The most recognized and well-known radar signature for tornadic supercells. This “hook-like” feature occurs when the strong counter-clockwise winds circling the mesocyclone (rotating updraft) are strong enough to wrap precipitation around the rain-free updraft area of the storm.

WHAT IS A HOOK ECHO? - theweatherprediction.com
A hook echo is displayed on radar reflectivity. It is a signature produced by precipitation held aloft that wraps around the mid-level mesocyclone. Since the mesocyclone has counterclockwise winds, the reflectivity signature of a hook echo will have a cyclonically shaped hook.
Radar Signatures for Severe Convective Weather: Hook Echo
A Hook Echo is used as one of many signatures suggesting a severe thunderstorm (usually a supercell). The presence of a Hook Echo often indicates the thunderstorm possesses a very strong, rotating updraft.
