Thunderstorm Bow Echo / What Is A Bow-echo Storm System (derecho) And Why Is It So ... - A second wave of storms came through.. Thunderstorm anvils may spread hundreds of miles downwind from the thunderstorm itself, and sometimes may spread upwind. A bow echo is a radar signature of a squall line that bows out as winds fall behind the line and circulations develop on either end. Wow heck of a morning in mn as over *70* reports of strong winds and large hail from massive bow echo targeting minneapolis! A strongly bowed echo may indicate high winds in the middle of the line, where the storms are moving forward most quickly.

The presence of a persistent bow echo signature should be associated with the presence of a strong rear inflow jet (rij) which, if it descends to the surface, is likely to be associated with damaging winds. A line of thunderstorms (dark red ovals) is bent into an arc or bow shape by fast winds (black arrows) from behind, called the rear inflow jet (rij).

Secondary features, such as the later onset of turbulence, the solitary echo in the radar return, and bow echo. Form bow echoes by differentially advecting a part of the squall line or thunderstorm cell forward, and by entraining dry, lower ue air into the rear ﬂank, which then erodes the back side of the advancing bow echo through the evaporation of hydrometeors.
