Tornadogenesis and Fractal Geometry. Huaqing Cai NCAR/ASP/ATD. Comparison of Garden City and Hays Mesocyclone. From Wakimoto and Cai, MWR, 2000. Markowski ( MRW , 2002)
Perhaps the most remarkable observational finding during the last 10 years is that the differences between tornadic and nontornadic supercells may be subtle, if even distinguishable, even in dual-Doppler radar analyses of the wind fields just prior to tornadogenesis.”
How vorticity is dependent on scale ?
Does it follow the power law ?
Or does it scaling with scale according to e1-D,
where e is the scale, D is a constant (fractal
R = 0.993
L = 0.3—9.6 km
xpv= | (Vr)max – (Vr)min | / D
x = 2* xpv for Rankine Vortex
