| Zusammenfassung |
| The spatial and temporal distribution of sea-level rise has the potential to
cause regional flooding in certain areas, and low-lying island countries are
severely at risk. Tuvalu, an atoll country located in the southwest Pacific
Ocean, has been inundated by this regional flooding for decades. Tuvaluans
call this regional flooding phenomenon King Tide, a term not clearly
defined, blaming it for loss of life and property in announcing their
intention to migrate. In this study, we clarified and interpreted King Tide,
and analyzed the factors of King Tide in Tuvalu. Using tide gauge and
topographical data, we estimated that 3.2 m could be considered the
threshold of King Tide, which implied half of the island of Tuvalu was
flooded with seawater. This threshold is consistent with the finding of the
National Oceanic and Atmospheric Administration that King Tide events occur
once or twice a year. We surveyed 28 King Tide events to analyze the factors
of regional flooding. Tide gauge and satellite altimeter data from 1993 to 2012 were cross-validated and indicated that the King Tide phenomenon is
significantly related to the warm-water effect. Warm water contributed to the
King Tide phenomenon by an average of 5.1% and a maximum of 7.8%.
The height of King Tide is affected by the combined factors of spring tide,
storm surge, climate variability, and, significantly, by the warm-water
effect. |
