Extreme wave heights in the North Atlantic from Altimeter Data

Estimation of extreme wave heights return period from short-term interpolation of multi-mission satellite data: application to the South Atlantic

“…However, as stated by Vinoth and Young (2011) and Young et al (2012), the availability of long time series, acceptable results can be obtained with the POT method. The 10 application of POT and GPD to estimate extreme wave return values, consequently, has shown to be suitable to undertake this study, as also proven by previous work (Challenor et al, 2004;Wimmer et al, 2006). …”

“…Carter (1993) computed monthly mean values of SWH in 2 • latitude × 2 • longitude bins and compared them with buoy data. These studies were followed by others during the past decade (Challenor et al, 2004;Chen et al, 2004;Wimmer et al, 2006). Challenor et al (2004) adopted a method similar to that of Carter (1993), representing satellite tracks by their respective medians within a 2 • square.…”

“…In a different way, Wimmer et al (2006) defined 2 • squares and computed the median from the different satellites in each cell.…”

“…In summary, the approach adopted so far in previous studies (Carter, 1993;Alves and Young, 2003;Challenor et al, 2004;Chen et al, 2004;Caires and Sterl, 2005;Wimmer et al, 2006) has consisted in using the monthly mean, median or maxima from different satellite along track data within a bin of a certain size and processing this information in order to estimate the 15 extreme wave for a certain return period. In this study, we carried out an extreme wave analysis based on satellite altimeter data generated by a multi-satellite database that was standardized, quality-controlled and corrected, from 1993 to 2015 (Queffeulou, 2004;Queffeulou and Croizé-fillon, 2017).…”

Risk and uncertainty in hydrometeorological hazards

“…However, stationarity might be approximated by taking logarithms of the ratio of successive observations (Coles, 2001), or assumed if the observed quantities are not closely linked with global atmospheric temperature (e.g. Wimmer et al, 2006), or the record relatively short (e.g. Baccini et al, 2008), or the spatial domain small (e.g.…”
