Abstract

An interesting swirl in the cloud base of a severe thunderstorm near Denver, Colorado, is documented with photographs and Doppler radar velocity measurements. The swirl, which produced two funnel clouds, may have been an eddy of a weak midlevel mesocyclone or a result of surface vorticity stretching by the storm's intense updraft.
