英文摘要 | Tide gauges provide a rich, long-term, record of the amplitude and spatiotemporal structure of interannual to multidecadal coastal sea level variability, including that related to North American east coast sea level “hotspots”. Here, using wavelet analyses, we find evidence for multidecadal epochs of enhanced decadal (10-15 year period) sea level variability at almost all long (>70 years) east coast tide gauge records. Within this frequency band, large-scale spatial covariance is time-dependent; notably, coastal sectors north and south of Cape Hatteras exhibit multidecadal epochs of coherence (∼1960-1990) and incoherence (∼1990-present). Results suggest that previous interpretations of alongcoast covariance, and its underlying physical drivers, are clouded by time- and frequency-dependence. Although further work is required to clarify the mechanisms driving sea level variability in this frequency band, we highlight potential associations with the North Atlantic sea surface temperature tripole and Atlantic Multidecadal Variability. |
