Description:
Monthly Maps of sea surface height are constructed for the North Atlantic Ocean using TOPEX/Poseidon altimeter data,
Mean sea surface height is reconstructed using a weighted combination of historical, hydrographic data and a synthetic
mean obtained by fitting a Gaussian model of the Gulf Stream jet to altimeter data. The resultant mean shows increased
resolution over the hydrographic mean, and incorporates recirculation information that is absent in the synthetic mean.
Monthly maps, obtained by adding the mean field to altimeter sea surface height residuals, are used to derive a set of zonal
indices that describe the annual cycle of meandering as well as position and strength of the Gulf Stream.
