Summary: We develop the theory of quasi linear systems of PDE introduced by V. P. Maslov. According to this theory many 2-D quasi linear systems of PDE possess only three algebras of singular solutions with properties of “structural” self-similarity and stability. They are the algebras of shock waves, “narrow” solitons and “square root” point singularities (solitary vortices). Their propagation is described by an infinite chain of ODE (the Hugoni√≥t-Maslov chains)obtained by a Taylor expansion of the solution of the shallow water equation around the point of the singularity. We consider the case of the “square root” singularity and connect it with the description of typhoons. We show the connection of this theory with the evolution of the center of typhoons.
