  Self-similarity in tornadic and some non-tornadic supercell flows is studied
and power laws relating various quantities in such flows are demonstrated.
Magnitudes of the exponents in these power laws are related to the intensity of
the corresponding flow and thus the severity of the supercell storm. The
features studied in this paper include the vertical vorticity and
pseudovorticity, both obtained from radar observations and from numerical
simulations, the tangential velocity, and the energy spectrum as a function of
the wave number. Connections to fractals are highlighted and discussed.
