At its recent meeting (September 2008) involving 20 climate modeling groups from around the world (i.e., most of the major groups performing climate change research today), the WCRP's Working Group on Coupled Modelling (WGCM), with input from IGBP's AIMES, agreed on a new set of coordinated climate model experiments, to be known as phase five of the Coupled… (More)
For technical reasons, the general circulation of the ocean has historically been treated as a steady, laminar flow field. The recent availability of extremely high-accuracy and high-precision satellite altimetry has provided a graphic demonstration that the ocean is actually a rapidly time-evolving turbulent flow field. To render the observations… (More)
Insight into the sources of eddy energy in the ocean can be obtained by studying the degree and nature of its temporal changes. As a preliminary to a dynamical and modeling discussion, we provide a description of the changes in variability on the annual and interannual time scales as seen in the TOPEX/POSEIDON altimeter data and in current meter records… (More)
We describe the surprising amount of high-frequency barotropic motion apparently present in TOPEXXPOSEIDON altimeter data, and the considerable predictive skill of present ocean general circulation models for what is actually observed. Models can thus beused to remove, at least partially, the energetic high-frequency signals from the data which otherwise… (More)
The impact of new geoid height models on estimates of the ocean circulation, now available from the Gravity Recovery and Climate Experiment (GRACE) spacecraft, is assessed, and the implications of far more accurate geoids, anticipated from the European Space Agency's (ESA) Gravity and Ocean Circulation Explorer (GOCE) mission, are explored. The study is… (More)
