Multiple vortex tornado
(or Multi-vortex tornado) a tornado in which two or more condensation funnels or debris clouds are present at the same time, often rotating about a common centre or about each other.
Multiple Vortex Tornado
A tornado that contains more than one vortex rotating around the main, central circulation.
It was changing rapidly in appearance as it quickly evolved into a large multiple vortex tornado. The huge vortex to the right of the road developed and dissipated within a minute, as another sub-vortex was forming to the left of the road.
The vortices can be tropical cyclones, hybrid or extratropical storms, even multiple vortex tornadoes or dust devils. Two vortices affecting one another can also be conceived as a VORTEX COUPLET.
