Point, spheroidal and ellipsoidal vortex models:- Their statistical properties-

In the quasi-geostrophic turbulence, the interactions of isolated coherent vortices dominate the turbulence dynamics. The continuous dynamical system of quasi-geostrophic turbulence may be reduced to a system of discrete vortices by constructing a vortex-based turbulence model. Miyazaki et al.[1] developed a simple vortex model, in which each coherent vortex i
