This phenomenon can be measured via the TORRO scale, and relative velocity images can identify convergence boundaries where these form. Rear flank downdrafts are responsible for this feature's signature hook echo on Doppler radar imagery. Most commonly found as satellite, rope, and wedge types, strong ones often descend from wall clouds in mesocyclones, and may feature multiple vortices. The "enha
This phenomenon can be measured via the TORRO scale, and relative velocity images can identify convergence boundaries where these form. Rear flank downdrafts are responsible for this feature's signature hook echo on Doppler radar imagery. Most commonly found as satellite, rope, and wedge types, strong ones often descend from wall clouds in mesocyclones, and may feature multiple vortices. The "enhanced" version of the scale currently in use ranks these from zero to five. For 10 points, name this weather phenomenon, a destructive rotating column of air.
