PEREZ-GARCIA, Ismael  and  SKIBA, Yuri N.. Tests of a numerical algorithm for the linear instability study of flows on a sphere. Atmósfera [online]. 2001, vol.14, n.2, pp.95-112. ISSN 0187-6236.

A numerical algorithm for the normal mode instability study of a steady nondivergent flow on a rotating sphere is developed. The algorithm accuracy is tested with zonal solutions of the nonlinear barotropic vorticity equation (Legendre polynomials, zonal Rossby-Harwitz waves and monopole modons).
