A supercell is a thunderstorm with a rotating updraft, which is classified as a mesocyclone. The rotating updraft is what sets a supercell apart from a typical thunderstorm. In order for a ...

The leading research on tornado formation says that the horizontal vortex of air turns vertical inside a severe thunderstorm with updrafts and downdrafts helping to create a mesocyclone ...
