will produce tornadoes
WORCESTER - About 75 weather enthusiasts got the lowdown on squall lines, shelf clouds, wall clouds and supercell thunderstorms
last week at a National Weather Service Skywarn spotter training class at the National Guard Armory on Skyline Drive.
Between May 2 and May 11, 2003, multiple supercell thunderstorms
developed and spawned numerous tornadoes, hailstorms and straight-line windstorms.
In supercell thunderstorms
, tornado formation is sensitive to the negative buoyancy and equivalent potential temperature of the rain-cooled, vorticity-rich air that emanates from downdrafts (e.g., Markowski and Richardson 2009, 2014; Davies-Jones 2015), with tornadogenesis likelihood generally increasing as buoyancy and equivalent potential temperature increase within the rain-cooled, vorticity-rich air--af least near the surface (e.g., Markowski et al.

These are typically associated with supercell thunderstorms
. Supercell thunderstorms
are often isolated from other thunderstorms and are characterized by the presence of a mesocyclone or a thunderstorm that has a deep, continuous rotation.
very often fail to produce tornadoes in seemingly favorable environments.
, on the other hand, often produce dangerous clear-air turbulence downwind that's essentially invisible.
