Current shear and turbulence during a near-inertial wave
Röhrs, Johannes; Halsne, Trygve; Sutherland, Graig; Dagestad, Knut-Frode; Hole, Lars Robert; Brostrøm, Gøran; Christensen, Kai Håkon (Journal article; Peer reviewed, 2023-04-11)Surface currents and turbulent mixing were observed during a near-inertial wave (NIW) using an accousting doppler current profiler (ADCP) and satellite-tracked drifters. Drifter trajectories sampled at three depth levels ... -
Ocean wave tracing v.1: a numerical solver of the wave ray equations for ocean waves on variable currents at arbitrary depths
Halsne, Trygve; Christensen, Kai Håkon; Hope, Gaute; Breivik, Øyvind (Journal article; Peer reviewed, 2023)Lateral changes in the group velocity of waves propagating in oceanic or coastal waters cause a deflection in their propagation path. Such refractive effects can be computed given knowledge of the ambient current field ... -
Resolving regions known for intense wave–current interaction using spectral wave models: A case study in the energetic flow fields of Northern Norway
Halsne, Trygve; Bohlinger, Patrik; Christensen, Kai Håkon; Carrasco, Ana; Breivik, Øyvind (Journal article; Peer reviewed, 2022)Oceanic current forcing in spectral wave models have recently been demonstrated to have a large impact on wave heights at scales between one and up to several hundred kilometers. Here we investigate the impact of such ... -
Wave modulation by strong currents: A study in the Lofoten Maelstrom and surrounding areas
Halsne, Trygve (Doctoral thesis, 2024-06-07)Bølger og strøm – allestedsnærværende trekk ved havet – er i en konstant tilstand av gjensidig vekselvirkning. Disse prosessene forårsaker sterkt inhomogene sjøtilstander. Samspillet dem imellom regulerer utvekslingsprosesser ...
