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).
