Abstract
Properties of particle dispersion in rotating stratified turbulence are studied numerically by using DNS of the Navier-Stokes equations under the Boussinesq approximation. Lagrangian particles are tracked with the cubic spline interpolation method by Yeung and Pope (1989). Both stratification and rotation impose anisotropy to turbulence, and thus the picture of particle dispersion in the vertical and the horizontal directions show distinctive difference: In the former, stratification suppresses the particle migration, and so does rotation. In the latter, strong stratification and rotation provide t2 growth of single particle dispersion with time, which can be explained as a result due to persistent shear structures developed in the flows.
