Jets and Waves in the Pacific Ocean

Analysis of the output of high-resolution ocean models reveals the presence of a class of flow structures that is intermediate in scale between the large-scale circulation and the geostrophic eddy field. These structures are coherent over considerably long zonal distances and have a relatively small meridional scale of 300–500km. They take the form of either quasipersistent multiple jets or long-crested Rossby waves with high-meridional and low-zonal wavenumbers. Here we discuss the properties of these features in the Pacific Ocean, possible mechanisms for their formation, and the potential impact on the transport of tracers.
