摘要：
Global computations of sea surface variability from repeated altimeter measurements usually exclude the shallow waters of continental shelfs and (semi‐)enclosed seas, because in these areas global marine tide models used to correct the altimetry derived sea surface heights loose their significance. If the marine tide model of Schwiderski is used for the North Sea, the computed variability reaches up to 20‐50 cm towards the shores. With the use of dedicated regional hydrodynamic models from the Dutch Rijkswaterstaat or the Proudman Oceanographic Laboratory, the computed variability decreases to ± 10 cm towards the shores. These much more realistic values also show the potential of altimetry to control these kind of regional models. Copyright © 1990, Wiley Blackwell. All rights reserved
