Variational Assimilation of Altimeter Data in a Multilayer Model of the Tropical Pacific Ocean
Publisher: American Meteorological Society
Abstract: A four-dimensional variational method is used to examine the extent to which a time sequence of altimeter measurements can determine the subsurface flow in a linear multilayer model of the tropical Pacific Ocean. The ...
Adjustment of Near-Equatorial Wind Stress with Four-Dimensional Variational Data Assimilation in a Model of the Pacific Ocean
Publisher: American Meteorological Society
Abstract: A four-dimensional variational scheme is described in which ocean observations are assimilated into an ocean general circulation model using wind stress forcing fields as control variables. Idealized (?twin?) experiments ...
Optimal Surface Salinity Perturbations of the Meridional Overturning and Heat Transport in a Global Ocean General Circulation Model
Publisher: American Meteorological Society
Abstract: Recent observations and modeling studies have stressed the influence of surface salinity perturbations on the North Atlantic circulation over the past few decades. As a step toward the estimation of the sensitivity of the ...
The Role of Air–Sea Interaction in Controlling the Optimal Perturbations of Low-Frequency Tropical Coupled Ocean–Atmosphere Modes
Publisher: American Meteorological Society
Abstract: In this paper the structure and dynamics of the optimal perturbations of tropical low-frequency coupled ocean?atmosphere oscillations relevant to El Niño?Southern Oscillation (ENSO) are explored. These optimal perturbations ...
Optimal Forcing Patterns for Coupled Models of ENSO
Publisher: American Meteorological Society
Abstract: The optimal forcing patterns for El Niño?Southern Oscillation (ENSO) are examined for a hierarchy of hybrid coupled models using generalized stability theory. Specifically two cases are considered: one where the forcing ...
The EU-FP7 ERA-CLIM2 Project Contribution to Advancing Science and Production of Earth System Climate Reanalyses
Publisher: American Meteorological Society
Abstract: AbstractThe European Reanalysis of Global Climate Observations 2 (ERA-CLIM2) is a European Union Seventh Framework Project started in January 2014 and due to be completed in December 2017. It aims to produce coupled ...
