Detection of Oceanic Quasi-Zonal Jets from Altimetry Observations
2012
Journal of Atmospheric and Oceanic Technology
Recent analyses of observations and ocean model outputs have revealed coherent low-frequency quasizonal jets in observed sea surface height (SSH) anomaly and model velocity fields. The jets were latent, that is, they were not detectable by eye, but revealed and selected by time-averaging procedures. Time-averaging procedures, when applied to fields that contain propagating features (eddies and waves), can create jetlike structures of nonphysical nature (artifacts). This paper suggests the
