Nonsingular surface quasi-geostrophic flow. (English) Zbl 0974.76512

Summary: The dynamics of large eddies in the atmosphere and ocean is described by the surface quasi-geostrophic equation, which is reminiscent of the Euler equations. Thermal fronts build up rapidly. Two different numerical methods combined with analytical criteria are used to show there are no singularities in finite time.
