maximum tangential velocity and the core radius of the Tsukuba tonrado
from its figure filmed. The velocity and pressure fields of the tornado
in upper layer was adapted from those of Rankine vortex in our scheme.
The result showed that the maximum tangential velocity could be
estimated properly. The evaluation of the relationship between the core
radius of tornado and the radius of debris, however, was required more.
