Rear flank downdraft tornadogenesis.

These areas of descending air are thought to be essential in the production of many supercellular tornadoes. Large hail within the rear flank downdraft often shows up brightly as a hook on weather radar images, producing the characteristic "hook echo", which often indicates the presence of a tornado. The rear flank downdraft can arise owing to negative buoyancy, which can be generated by cold
