24th Conference on Severe Local Storms


DOW observations of multiple vortex structure in several tornadoes

Joshua Wurman, Center for Severe Weather Research, Boulder, CO; and K. A. Kosiba

The DOW radars have observed several tornadoes that have

exhibited multiple vortex structure. Recently, these

include the Seward (2007) tornado, which had a multiple

vortex core flow region with a 1.5-2.0 km, making it the

largest core flow every quantitatively documented.

Additionally, in 2008, multiple vortex structure was

observed by a DOW at close range in the Quinter, Kansas

tornado and in the Glen Elder, Kansas tornado. The

intensity, spacing, motion, and other characteristics

of these multiple vortices are compared to those

previously analyzed, inlcluding Spencer, South Dakota

(1998), and Mulhall (1999).
