Supercell• Rotating thunderstorm with updrafts and
downdrafts structured so it can maintain itself for several hours
• What makes a supercell different from all other thunderstorms?– ROTATION
• Requires both speed and directional wind shear• Contains a mesocyclone
– A cyclonically rotating vortex, 2-10 km in diameter, within a convective storm
• Often a “right-mover”– Moves to the right of the general flow where it gets the
best air and rotation is stronger

Three Supercell Classifications
• Low Precipitation (LP)– Little to no precipitation– Generally does not produce tornadoes
• Classic– Contains structure described already
• High Precipitation (HP)– Lots of precipitation– Rain-wrapped tornadoes

The Take-Home Message About Supercells
• Supercells are rotating thunderstorms
• Supercells have one rotating updraft and one or more downdrafts
• Supercells form in environments with strong wind shear (change in speed AND direction with height)
• Supercells often produce tornadoes
