Mesocyclone information

A mesocyclone is a meso-gamma mesoscale (or storm scale) region of rotation (vortex), typically around 2 to 6 mi (3.2 to 9.7 km) in diameter, most often...

detected rotation algorithm that indicates the likely presence of a strong mesocyclone that is in some stage of tornadogenesis. It may give meteorologists the...

cyclones and subtropical cyclones also lie within the synoptic scale. Mesocyclones, tornadoes, and dust devils lie within the smaller mesoscale. Upper level...

A supercell is a thunderstorm characterized by the presence of a mesocyclone, a deep, persistently rotating updraft. Due to this, these storms are sometimes...

landfall. Mesovortices can spawn rotation in individual thunderstorms (a mesocyclone), which leads to tornadic activity. At landfall, friction is generated...

updraft within a storm. Rotating wall clouds are an indication of a mesocyclone in a thunderstorm; most strong tornadoes form from these. Many wall clouds...

in the lower portions of a storm as air and precipitation flow into a mesocyclone, resulting in a curved feature of reflectivity. The echo is produced...

formation. The cycle begins when a strong thunderstorm develops a rotating mesocyclone a few miles up in the atmosphere. As rainfall in the storm increases...

cyclones. Mesocyclones form as warm core cyclones over land, and can lead to tornado formation. Waterspouts can also form from mesocyclones, but more...

surface winds and heat-induced lifting, rather than from a tornadic mesocyclone aloft. The phenomenon was first verified in the 2003 Canberra bushfires...

vertical wind shear. A supercell has a rotating updraft (mesocyclone) and a downdraft. The mesocyclone is created when horizontal vortices created by the wind...

downdraft (RFD) is a region of dry air wrapping around the back of a mesocyclone in a supercell thunderstorm. These areas of descending air are thought...

supercell. Another mechanism for DRC formation is associated with updraft-mesocyclone cycling. In this process, a new hook echo and subsequent DRC can form...

powerful updraft is often an indication of, or is facilitated by, a mesocyclone. A mesocyclone is not strictly necessary for BWER development. Storm rotation...

Most tornadoes are associated with a larger parent circulation, the mesocyclone on the back of a supercell thunderstorm. Dust devils form as a swirling...
