This spectacular photo of a super cell that spawned a tornado about a minute later that touched down in Broken Arrow, OK was taken last night with an iphone from beneath a car with no special lighting or effects. Photo by Brian Ring (He gave explicit permission to use this photo on Daily Spec as long as he is properly credited)

The well formed wall cloud is quite spectacular. The photo is indicative of the defining characteristic of super cell thunderstorms - a Mesocyclone or rotating vortex of upwardly flowing air which can be detected using algorithms in Doppler Weather Radar which search for a Hook Echo.

Unlike the devastating F5 tornado that struck Moore, OK last week, the tornado produced by this cell less than a minute after the picture was taken was only an F1 and caused very little damage.
