Changes in atmospheric circulation over the North Atlantic and sea‐surge variations along the Belgian coast during the twentieth century
Abstract Wintertime (October‐to‐March period) 99th percentile of sea level (sea surges) at Ostend has increased at a rate of + 3 mm/year (+1 mm/year) from 1925 to 2000. Relationships between daily sea surge at Ostend and five weather regimes—Zonal (ZO), East Atlantic (EA), Greenland Above (GA), Bloc...
