It is a little known but amazing phenomenon that sometimes accompanies tornadoes – multiple vortices coming from one larger twister. Storm chasers descended on the area of yesterday’s deadly tornado outbreak and two were able to capture amazing video of what looks like small tornadoes circling a larger twister.
When witnessed from the ground, multiple vortex tornadoes are an amazing sight. The larger twister will appear no different than what one might expect, but smaller vortices will be seen rapidly circling around and through the main funnel.
These suction vortexes are usually short-lived and will die out as the main funnel moves and then new satellites will reappear. These satellite vortices are oftentimes present but not visible due to debris and clouds.
Storm chaser Andy Gabrielson captured amazing video of a multiple vortex tornado as it tore through the Oklahoma countryside.
