TLDR
In this paper, the authors show that a significant fraction of the detrended sea level variance is forced by the region's along-shelf wind stress, and that the changes observed along the coast and over the shelf may influence the Gulf Stream path downstream of Cape Hatteras.Abstract:
[1] Annually averaged sea level (1970–2012) measured by tide gauges along the North American east coast is remarkably coherent over a 1700 km swath from Nova Scotia to North Carolina. Satellite altimetry (1993–2011) shows that this coherent interannual variability extends over the Middle Atlantic Bight, Gulf of Maine, and Scotian Shelf to the shelf break where there is a local minimum in sea level variance. Comparison with National Center for Environmental Prediction reanalysis winds suggests that a significant fraction of the detrended sea level variance is forced by the region's along-shelf wind stress. While interannual changes in sea level appear to be forced locally, altimetry suggests that the changes observed along the coast and over the shelf may influence the Gulf Stream path downstream of Cape Hatteras.read more

An extreme event of sea-level rise along the Northeast coast of North America in 2009–2010
TL;DR: This analysis of long-term tide gauge records shows that this extreme SLR event is a combined effect of two factors: an observed 30% downturn of the Atlantic meridional overturning circulation during 2009-10, and a significant negative North Atlantic Oscillation index.

Forcing Factors Affecting Sea Level Changes at the Coast

TL;DR: In this article, the authors review the characteristics of sea level variability at the coast focussing on how it differs from the variability in the nearby deep ocean and how it contributes to the historical mean sea level records obtained from tide gauges which are now used routinely in large-scale climate research.

Geographic Variability of Sea-Level Change
TL;DR: In this paper, the integration of all these different processes into interpretations of past changes and projections of future change is an active area of research, and the past contributions of these processes requires information from sources covering a range of timescales, including geological proxies, tide-gauge observations from the last ~3 centuries, and satellite-altimetry data from last ~2 decades.

Mean sea-level variability along the northeast American Atlantic coast and the roles of the wind and the overturning circulation
Philip L. Woodworth,M. A. Morales Maqueda,Vassil Roussenov,Richard G. Williams,Chris W. Hughes,Chris W. Hughes +5 more
TL;DR: The variability in mean sea level (MSL) during 1950-2009 along the northeast American Atlantic coast north of Cape Hatteras has been studied, using data from tide gauges and satellite altimetry and information from the LHC ocean model, thereby providing new insights into the spatial and temporal scales of the variability as mentioned in this paper.

TL;DR: The NCEP/NCAR 40-yr reanalysis uses a frozen state-of-the-art global data assimilation system and a database as complete as possible, except that the horizontal resolution is T62 (about 210 km) as discussed by the authors.

Decadal Trends in the North Atlantic Oscillation: Regional Temperatures and Precipitation
TL;DR: An evaluation of the atmospheric moisture budget reveals coherent large-scale changes since 1980 that are linked to recent dry conditions over southern Europe and the Mediterranean, whereas northern Europe and parts of Scandinavia have generally experienced wetter than normal conditions.
