Figure 6.47. (a) Radial profile of azimuthally averaged azimuthal wind component in a
tornado in Kansas on May 15, 1999, as estimated from data collected by the U. Mass.
W-band, mobile Doppler radar. Also plotted are the radial profile of the azimuthal velocity
for a Burgers-Rott vortex having the same maximum wind speed and radius of maximum
wind, the vorticity of the tornado, and the vorticity of the Burgers-Rott vortex. The key to each
profile is shown in the inset at the upper right (adapted from Tanamachi et al., 2007). (b) Radial
(R) profile of azimuthal (tangential) wind (V) in a Burgers-Rott vortex. R core is the core radius;
V max is the maximum azimuthal wind speed (adapted from Brown and Wood, 2012).
