Anomalous diffusion in rotating stratified turbulence
Diffusion in rotating and stratified fluids is one of the central subjects in geophysical and astrophysical dynamics. As a fundamental property of diffusion, particle dispersion has been studied extensively in various fields of engineering, physics and mathematics. In this paper, we report features of the dispersion of Lagrangian fluid particles in rotating stratified flows using the Direct Numerical Simulations (DNS) of the Navier-Stokes equations. And for calculation of particle dispersion, we use the cubic spline interpolation method by Yeung and Pope .
