Description
We prove limit theorems for small-scale pair dispersion in
velocity fields with power-law spatial spectra and wave-number
dependent correlation times. This result establishes rigorously
a family of generalized Richardson's laws with a limiting case
corresponding to Richardson's $t^3$ and $4/3$-laws.
