Non-stationarity in the NAO-Gulf Stream interannual relationship

The North Atlantic Oscillation (NAO) is widely recognized as a primary driver of the Gulf Stream (GS) path variability on interannual to decadal timescales. While the canonical view holds that the GS path responds to the NAO in a temporally stationary and approximately linear manner, we show that the sign and strength...

Numerical Modelling of the Barotropic Tides in the Gulf of Aden

The Gulf of Aden (GA) is a strategically dynamic water basin linking the Red Sea basin with the Arabian Sea via the Bab el Mandeb Strait. In spite of its importance for oil transportation globally and regional hydrodynamics, tidal propagation remains relatively understudied. Thus, in this study, a depth-averaged 2D bar...

Satellite Altimetry Reveals Spatially Heterogeneous Sea-Level Rise, Mesoscale Variability, and Increasingly Frequent Extremes in the East Sea (Sea of Japan), 1993–2024: Dokdo in Regional Context

The East Sea (Sea of Japan) is a semi-enclosed marginal sea with an energetic mesoscale eddy field along the Tsushima Warm Current and its subpolar front. Unlike prior point reconstructions of Dokdo sea level, we use 0.125° gridded satellite altimetry (DUACS, 1993–2024) to map the spatial structure of the basin’s rise,...

Atmospheric and oceanic controls of coastal upwelling in the northern Gulf of Guinea: insights from Keta, Ghana

Coastal upwelling along the northern Gulf of Guinea sustains fisheries and regulates tropical Atlantic sea-surface temperature, yet the combined roles of atmospheric and oceanic forcing remain incompletely characterized. This study quantifies the joint interaction between wind-driven Ekman transport and geostrophic...

Numerical Simulations and Analyses of the Long-Term Characteristics of Ocean Waves in the Bohai Sea Under a Coupling Model

A coupled WRF–ROMS–SWAN framework is used to investigate the long-term wave characteristics of the Bohai Sea through a 20-year hindcast from 2002 to 2022. The model results are validated against CMEMS current data, field wave measurements, and CCMP wind products, showing good agreement with the reference datasets. Thre...

Spatiotemporal variability of sea level fluctuations according to IMMOAD SSHA data after additional correction of the tidal component

Seasonal and interannual variability of sea level fluctuations in the northwestern Pacific Ocean and the Far Eastern seas was analyzed using the empirical orthogonal function decomposition of the original data series. The study is based on a data set of altimetric observations from the IMMOAD SSHA for the period 1993–2...
