What is a multiple vortex tornado? Is it always stronger that a single vortex tornado?
The individual vortices are easy to see in this 1990 multiple vortex tornado.A multiple vortex tornado is one that has mini vortices inside the bigger main vortex. In a way, it is a tornado inside tornado, and can be very intense, with both big and small vortices to create small areas of incredible damage. A photograph of a multiple vortex tornado was taken in Peotone, Illinois in 1948, but it was not recognized for what it was back then. Dr. Fujita proposed this theory in his research, but it was not accepted as fact for many years. Interestingly enough, there are illustrations from the 19th century that show the same multiple vortex structure. It should be pointed out, however, that single vortex tornadoes can be just as intense as multiple vortex tornadoes. • I have heard that you can tell whether the tornado had a single or multiple vortex structure by looking at the ground afterwards. Is that true? The tornado that passed over this field had multiple vortices. Multiple vortex torn

Is that true? Multiple vortex tornadoes sometimes leave patterns in corn stubble or other crops that are called “spiral ground markings”. These can best be seen during an aer
