Meaning of BOW ECHO in English

BOW ECHO

A radar echo which is linear but bent outward in a bow shape.

Damaging straight-line winds often occur near the "crest" or center of a bow echo. Areas of circulation also can develop at either end of a bow echo, which sometimes can lead to tornado formation - especially in the left (usually northern) end, where the circulation exhibits cyclonic rotation .
