“…The study showed in addition that the periods of high storm activity furthermore coincided with positive decadal trends in the North Atlantic Oscillation (NAO) index (Hurrell 1995). A similar NAO link and strong decadal trends are also visible in extreme sea levels in the southeastern North Sea (Dangendorf et al 2013a;Mudersbach et al 2013).…”

“…The largest contribution to the observed variability in the storm surge record can be found on time scales up to a few decades. From a variety of studies, it is well known that especially during the winter season a considerable fraction of sea level variability can be explained by the NAO (e.g., Yan et al 2004;Dangendorf et al 2012). It is also obvious that this relationship does not only exist for mean but also for extreme sea levels (Woodworth et al 2007;Dangendorf et al 2013a).…”

It is also obvious that this relationship does not only exist for mean but also for extreme sea levels (Woodworth et al 2007;Dangendorf et al 2013a). We therefore examined the relationship for the winter season by comparing the updated station-based NAO index from Jones et al (1997) to the four upper percentiles of storm surges (Table 2).…”

The detection of potential long-term changes in historical storm statistics and storm surges plays a vitally important role for protecting coastal communities. In the absence of long homogeneous wind records, the authors present a novel, independent, and homogeneous storm surge record based on water level observations in the North Sea since 1843. Storm surges are characterized by considerable interannual-to-decadal variability linked to large-scale atmospheric circulation patterns. Time periods of increased storm surge levels prevailed in the late nineteenth and twentieth centuries without any evidence for significant long-term trends. This contradicts with recent findings based on reanalysis data, which suggest increasing storminess in the region since the late nineteenth century. The authors compare the wind and pressure fields from the Twentieth-Century Reanalysis (20CRv2) with the storm surge record by applying state-of-the-art empirical wind surge formulas. The comparison reveals that the reanalysis is a valuable tool that leads to good results over the past 100 yr; previously the statistical relationship fails, leaving significantly lower values in the upper percentiles of the predicted surge time series. These low values lead to significant upward trends over the entire investigation period, which are in turn supported by neither the storm surge record nor an independent circulation index based on homogeneous pressure readings. The authors therefore suggest that these differences are related to higher uncertainties in the earlier years of the 20CRv2 over the North Sea region.

“…On a local scale its temporal changes are the product of a couple of (inherently coupled) processes such as volume and mass changes due to (i) exchange of water with the atmosphere and the continents and (ii) mass redistribution due to changing winds and sea level pressure [27][28][29][30], and vertical land motion [32,33]. These variations vary locally and can be as large as ∼ ±80cm on a inter-monthly or ∼ ±50cm on an inter-annual time scale.…”

We perform a statistical analysis of measured time series of sea levels at various coastal locations in the UK, measured at time differences of 15 minutes over the past 20 years. When the astronomical tide and other deterministic components are removed from the record, a stochastic signal corresponding to the meteorological component remains, and this is well-described by a superstatistical model. We do various tests on the measured time series, and compare the data at 5 different UK locations. Overall the χ 2 -superstatistics is best suitable to describe the data, in particular when one looks at the dynamics of sea-level differences on short time scales.

Temporal variations of the seasonal sea level harmonics throughout the 20 th and early 21 st century along the United States Gulf coast are investigated. A significant amplification of the annual sea level cycle from the 1990s onward is found, with both lower winter and higher summer sea levels in the eastern Gulf. Ancillary data are used to build a set of multiple regression models to explore the mechanisms driving the decadal variability and recent increase in the annual cycle. The results suggest that changes in the air surface temperature toward warmer summers and colder winters and changes in mean sea level pressure explain most of the amplitude increase. The changes in the seasonal sea level cycle are shown to have almost doubled the risk of hurricane induced flooding associated with sea level rise since the 1990s for the eastern and north-eastern Gulf of Mexico coastlines.
