## Abstract The propagation of energy on the sphere as described by the linear barotropic vorticity equation is studied. For simple flows, the concept of group velocity is examined. Planetaryβscale vorticity anomalies exhibit a surprising lack of dispersion in a hemispheric domain. On the sphere, t
