Recent video of double wedge tornadoes? where and when?

[Doug Lee]

I remember seeing some aerial photographs of tornado tracks similar to the pattern in Mike's post. IIRC, they were in Grazulis's The Tornoado: Nature's Ultimate Windstorm. I"m not sure if the pics are online, but if I can find them, I'll either post them or a link to them.

I'm not sure if the portable Doppler measurements can discriminate between main circulation and suction vortices when it tracks....anyone know?

Some of the DOW observations I think have shown this, and probably others. DOW observations of the Mulhall tornado from May 3 1999 was described by Lee and Wurman (2005) captured suction vortices, although they were not well resolved. Would not be surprised if there are other similar observations, but you probably need a very big tornado (like Mulhall) to have much hope, and preferably a radar with a very fine beamwidth.

First: Sorry to have contributed in taking this thread off topic, we should have moved it.

At Mulhall they were 4 KM away, but the suction spots were large. Josh Wurman told me they can measure one about 50 meters across within 1 KM range. He said Great Bend yielded data in 2007 which I think is not yet published. I need to catch up on this subject, these days I tend to only read stuff that helps my forecasting.

Also, I was on Mulhall (north of OKC) until the police told me to cease and desist my actions and leave the area. I was setting up a tripod. So I didn't see it in its later life cycle.
