Incredible tornadoes spinning the wrong way! In this video, we’re going to showcase and explain these sneaky, anticyclonic freaks of nature and their common locations within a storm… So that you won’t be fooled.

CYCLONIC AND ANTICYCLONIC MEANING:
98 percent or more of the world’s tornadoes rotate the same direction as Earth. When atmospheric motion rotates the same direction as the planet,
we refer to the rotation as being cyclonic. Thats counterclockwise in the northern hemisphere but clockwise in the southern hemisphere. Thus, these typical tornadoes are referred to as being cyclonic. But Every now and then a tornado spins the other way. We refer to these deviant tornadoes as anticyclonic.
Most of the anticyclonic tornadoes I’ve observed were companions of a cyclonic tornado or rotation in a supercell. These rare tornadoes are often not anticipated and can sneak up on observers fixated on the more business end of the storm. Some anticyclonic tornadoes develop as smaller satellites orbiting around a parent tornado. Sometimes they manifest as landspouts in non-supercellular storms. Most of the cases I’ve observed developed in a predictable region of a right-moving supercell. But because of their infrequency, even trained observers may not anticipate these anticyclonic threats and thus may get caught off guard. In most cases the anticyclone threat is small, but not always. Recognizing the cloud patterns in this video may help a spotter anticipate anticyclonic tornado development.
SIMLA COLORADO ANTICYCLONIC TORNADOES:
On June 5, 2015, Dr Anton Seimon & Dr. Tracie Seimon documented an extremely photogenic family of tornadoes near Simla Colorado, several of which were strongly anticyclonic. A huge thanks goes out to Anton and Tracie for allowing me to showcase their never-before-seen, beautiful captures.
STRONGEST ANTICYCLONIC TORNADO:
Several anticyclonic F3’s have been documented on the original Fujita scale and on April 4, 1981, shortly after midnight, A violet anticyclonic tornado terrorized West Bend, Wisconsin. It injuring 53 people and ended the lives of three. This rare nightmare would earn an F4 rating. The most powerful anticyclonic tornado ever recorded.
