RISGlobal Characteristics of Ocean Variability Estimated from Regional TOPEX/POSEIDON Altimeter Measurements
Publisher: American Meteorological Society
Abstract: Three years of altimetric data from the TOPEX/POSEIDON spacecraft have been used to study characteristics of eddy variability over the World Ocean. The nature of the variability and its spatial structure are characterized ...
Geosat Data Assimilation with Application to the Eastern North Atlantic
Publisher: American Meteorological Society
Abstract: An attempt is made to determine the three-dimensional ocean circulation from satellite altimeter measurements by assimilating Geosat sea surface height data into an eddy-resolving quasigeostrophic (QG) model of the eastern ...
Adjusting Internal Model Errors through Ocean State Estimation
Publisher: American Meteorological Society
Abstract: Oceanic state estimation is a powerful tool to estimate internal model parameters simultaneously with the model?s initial conditions and surface forcing field that jointly would bring a model into consistency with time-varying ...
On Eddy Characteristics, Eddy Transports, and Mean Flow Properties
Publisher: American Meteorological Society
Abstract: Estimates of eddy energy and eddy scales obtained previously from TOPEX/POSEIDON (T/P) altimeter data are interpreted in the context of a baroclinically unstable flow field. From the observations an integral timescale Talt ...
Response of Regional Sea Level to Atmospheric Pressure Loading in a Climate Change Scenario
Publisher: American Meteorological Society
Abstract: The regional response of the global ocean to low-frequency changes in atmospheric pressure loading, ?ib, is analyzed as it occurs in the Max Planck Institute for Meteorology (MPI-M) coupled ocean?atmosphere climate model ...
Variability of the Meridional Overturning in the North Atlantic from the 50-Year GECCO State Estimation
Publisher: American Meteorological Society
Abstract: The German partner of the consortium for Estimating the Circulation and Climate of the Ocean (GECCO) provided a dynamically consistent estimate of the time-varying ocean circulation over the 50-yr period 1952?2001. The ...
Decadal Sea Level Changes in the 50-Year GECCO Ocean Synthesis
Publisher: American Meteorological Society
Abstract: An estimate of the time-varying ocean circulation, obtained over the period 1952?2001, is analyzed here with respect to its decadal and longer-term changes in sea level. The estimate results from a synthesis of most of the ...
The Effect of Ocean Currents on Sea Surface Temperature Anomalies
Publisher: American Meteorological Society
Abstract: Global and regional correlations between observed anomalies in sea surface temperature and height are investigated. A strong agreement between the two fields is found over a broad range of latitudes for different ocean ...
Assessing ENSO Simulations and Predictions Using Adjoint Ocean State Estimation
Publisher: American Meteorological Society
Abstract: Simulations and seasonal forecasts of tropical Pacific SST and subsurface fields that are based on the global Consortium for Estimating the Circulation and Climate of the Ocean (ECCO) ocean-state estimation procedure are ...
Influence of Tropospheric Water Vapor Corrections on Geosat Altimetry in the North Atlantic Ocean
Publisher: American Meteorological Society
Abstract: Cicosal sea surface height (SSH) data in the tropical and midlatitude North Atlantic are analyzed with and without water vapor (WV) correction to study the WV influence on along-track SSH anomaly profits, mesoscale SSH ...
