The large majority of the tornadoes in the northern hemisphere spin counterclockwise (cyclonically), but about 1 in 100 tornadoes spin clockwise. Actually, it has little to do with being in the northern hemisphere, as tornadoes do not last long enough for the effects of Coriolis to impact it.
Since a tornado is a spinning column of air with an axis of rotation, the tornado itself is a vortex. Some tornadoes also contain smaller vortices call suction vortices. Theseâ¦ vortices circle with the rotation of the main vortex and carve curved paths of more severe damage within the main damage path. A tornado with such features is called a multiple vortex tornado.
