| Zusammenfassung |
| Although the global mean sea-level budget for the 20th century can now be
closed, the understanding of sea-level change on a regional scale is still
limited. In this study we compare observations from tide gauges to regional
patterns from various contributions to sea-level change to see how much of
the regional measurements can be explained. Processes that are included are
land ice mass changes and terrestrial storage changes with associated
gravitational, rotational and deformational effects, steric/dynamic changes,
atmospheric pressure loading and glacial isostatic adjustment (GIA). The
study focuses on the mean linear trend of regional sea-level rise between
1961 and 2003. It is found that on a regional level the explained variance of
the observed trend is 0.87 with a regression coefficient of 1.07. The
observations and models overlap within the 1σ uncertainty range in all
regions. The main processes explaining the variability in the observations
appear to be the steric/dynamic component and the GIA. Local observations
prove to be more difficult to explain because they show larger spatial
variations, and therefore require more information on small-scale processes. |
