Supercell Spectrum
Hybrid
Some supercells attain the charactersitics of more
than one type of supercells at the same time.
Other supercells evolve from one form to the
other. For instance, Doswell suggests that
“…it is likely that most LP storms do not become
tornadic unless they evolve along the supercell
spectrum toward the Classical structure…”
