Vertical Structure of Ocean Pressure Variations with Application to Satellite-Gravimetric Observations

摘要: AbstractThe nature of ocean bottom pressure () variability is considered on large spatial scales and long temporal scales. Monthly gridded estimates from the Gravity Recovery Climate Experiment (GRACE) Release-05 new version 4 bidecadal state estimate Consortium for Estimating Circulation Ocean (ECCO) are used. Estimates GRACE ECCO generally in good agreement, providing an independent measure quality both products. Diagnostic fields used to compute barotropic (depth independent) baroclinic dependent) components. The relative roles processes found vary with latitude time scale: variations at higher latitudes shorter periods affected by processes, whereas fluctuations lower longer can be influenced effects, broadly consistent theoretical scaling arguments.
