A core vortex is specified initially, which has a hurricane-like tangential
wind profile (see Fig. 2) defined as follows:

Fig. 2. Radial profiles of the hurricane-like vortex for nondimensional (a) tangential
wind, (b) angular velocity, (c) vorticity, and (d) vorticity gradient. To obtain tangential
wind in ms 1 , multiply by 50. To obtain angular velocity or vorticity in s 1 , multiply
by 5 × 10 5 . To obtain vorticity gradient in m 1 s 1 , multiply by 5 × 10 11 .Toobtain
radial displacement in km, multiply by 1000.
