A '''mesocyclone''' is a meso-gamma [[Mesoscale meteorology|mesoscale]] (or storm scale) region of rotation ([[vortex]]), typically around {{convert|2 to 6|mi|km|abbr=on}} in diameter, most often noticed on radar within [[thunderstorm]]s. In the [[Northern Hemisphere]], it is usually located in the right rear flank (back edge with respect to direction of movement) of a [[supercell]], or often on the eastern, or leading, flank of a [[Supercell#High Precipitation (HP)|high-precipitation]] variety of supercell. The area overlaid by a mesocyclone’s circulation may be several miles (km) wide, but substantially larger than any [[tornado]] that may develop within it, and it is within mesocyclones that [[Tornado intensity|intense tornadoes]] form.<ref name="NWSGlossaryMESO" />
