Geophysical fluid dynamics, waves and vortices in the atmosphere and oceans, statistical mechanics, sea ice dynamics
Oliver Bühler works on fundamental topics in wave mean-flow/vortex interaction. For example, he and a collaborator have recently uncovered a mechanism by which a wave-vortex interaction can cause a persistent, cumulative change in the mean state in the absence of dissipation or breaking (Buhler and McIntyre 2003). Such an effect brings into question fundamental parameterizations of gravity waves used in atmospheric models. Buhler also works on coastal vortex dynamics, statistical mechanics, and stratospheric transport.
