Multivortex tornado
A multivortex tornado is a tornado that consists of several smaller sub-vertebrae that circle around a common center or within a common center. Multivortex tornadoes are not to be confused with twin tornadoes, where each vertebra forms its own center and develops independently of the other vertebra. The sub-vertebrae usually appear in groups of 2 to 5 vertebrae at a time, with each vertebra usually lasting less than a minute. The vortices within the center are often not visible from the outside.
