- Most dangerous because of
strong winds, hail and long-lived or multiple tornadoes.
- A single supercell can last several hours. The updraft has
a continuous feed of inflow air.
- Wind shear vector turns clockwise (veers) with height in the
- Propagation is continuous rather than discreet. The storm
usually travels slower and to the right of the mean wind.
- Research found average maximum size of multicell hailstone
of 1.9 cm, while supercell is 5.3 cm. Average hail swath is 10
km and 20.2 km for the multicell and supercell storms, respectively.
- The supercell is a preferential organization resulting from
an intense, moist, convective updraft and atmospheric physics
governing such processes.
