| Zusammenfassung |
| Anomalies of dynamic height derived from an analysis of Argo
profiling buoys data are analysed to assess the relative roles of
contributions from temperature and salinity over the North Atlantic
for the period of 1999–2004. They are compared with dynamic
topography anomalies based on TOPEX/Poseidon and Jason altimetry.
It is shown that the halosteric contribution to the anomalies of
dynamic height is comparable in magnitude to the thermosteric one
over the period analyzed. Taking both salinity and temperature into
account improves the agreement between zonally averaged trends in
the satellite dynamic topography and dynamic height increasing the
correlation between them to 0.73 from 0.63 when only temperature
variability is taken into account. The implication of this result
is that the salinity contribution cannot be neglected in the North
Atlantic and that one cannot rely on estimating the thermosteric
part by anomalies in the sea surface dynamic topography derived
from the satellite altimetry. |
