✦ Synopsis

We focus in the first part of this article on the explicit estimate, in terms of the Rossby number ε, of the convergence speed of the solution of the primitive equations to the unique and global solution of the quasigeostrophic system, with better results when ν = ν . The second part is devoted to the proof of the persistence, when the Rossby number goes to zero, of the structure of tangential regularity for the primitive equations with diffusion and viscosity.

When studying the approximation of the wave functions of the \(H\)-atom by sums of Gaussians, Klopper and Kutzelnigg [KK] and Kutzelnigg [Ku] found an asymptotic of \(\exp [-\gamma \sqrt{n}]\). The results were obtained from numerical results and justified by some asymptotic expansions in quadrature

## Abstract The interaction of vortex patches in relation to the observed scales and features reported in Part I of this paper is investigated. It is found that the initial approach of compound vortices, such as tropical cyclones, arises from distortion of their, weaker, outer vorticity fields. Car
