Case Study of Severe Weather in Bow Echoes

Severe storms often possess storm scale features such as bowing lines of radar echoes and bookend vortices. Storms possessing these types of features often produce straight-line wind events. It is unclear if the convergent flow from the vortices is responsible for causing the echo to bow out or if the line itself causes the vortices to form as part of a wake phenomena. Using Doppler radar data from several historical events, the evolution of the storm features will be monitored with respect to timing of the damaging winds. By examining the timing of the evolution of the Doppler radar fields we will examine the timing of the onset of the damaging winds to see which storm scale feature initiates the wind.
