NWS Louisville: Supercell Structure and Dynamics (Site not responding. Last check: 2007-11-06) |
 | | Supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes. |
 | | For example, on supercell hodograph, winds at 1 km altitude are from the southeast, stronger from the south at 2 km, with winds increasing in speed (longer vectors from (0,0) point to each dot) and veering to southwest at higher altitudes. |
 | | HP supercells occur in environments with rich low-level moisture and moderate-to-strong wind shear, and are a threat for tornadoes, large hail, damaging winds, and flash flooding. |
