Types of Thunderstorms
single cell, multicell clusters, multicell lines and supercells
The array of thunderstorms within the
spectrum reflects our current scientific
understanding. Thus, while the spectrum is
very useful, it is neither perfect nor a
final solution. Nevertheless, arrangement
of storms within the spectrum is dependent
on updraft strength, here represented by
different colors; relative frequencies of
these updraft strength categories, as
indicated by differing lengths on the upper
bar graph; and relative threats of the updraft
categories, here represented by the lengths on
the bottom bar graph.
||Thus, while a "strong"
updraft is less common than a "weak" updraft,
the relative threat to life and property is
greater with the "strong" updraft storm. Similarly,
"intense" updraft storms are quite rare but
inflict a disproportionate amount of damage
and personal injury.
