Stratospheric planetary flows from the perspective of the Euler equation on a rotating sphere

Abstract: We discuss stationary solutions of Euler's equation on a rotating sphere and their relevance to the dynamics of stratospheric flows in the atmosphere of the outer planets of our solar system. We present some rigidity results (showing that certain stationary solutions must be either zonal or rotated zonal solutions) and some stability results of low-mode Rossby-Haurwitz stationary solutions. This is joint work with Pierre Germain (Courant Institute, New York).
