The dynamics of large eddies in the atmosphere and oceans 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.
