The authors study dispersion phenomena occuring in singular perturbation models of fluid dynamics. More precisely, they examine the small Rossby number limit of solutions to incompressible Navier-Stokes equations in three dimensions. The convergence to the corresponding limiting two-dimensional Navier-Stokes equations is proved by using anisotropic Strichartz-type estimates which take into account viscosity effects.
