Low-frequency variability of the global sea surface height revealed by satellite altimetry

The focus of the paper is the variability of the North Atlantic Ocean. Large-scale low-frequency variability of the North Atlantic has recently been studied based on model simulations, as well as analysis of altimetry data in conjuction with in-situ data. These studies have suggested significant interannual to decadal changes in the North Atlantic in the 1990's.
