    Description: The repercussions of surface ocean currents for the near-surface wind and the air-sea momentum flux are investigated in two versions of a global climate model with eddying ocean. The focus is on the effect of mesoscale ocean current features at scales of less than 150 km, by considering high-pass filtered, monthly-mean model output fields. We find a clear signature of a mesoscale oceanic imprint in the wind fields over the energetic areas of the oceans, particularly along the extensions of the western boundary currents and the Antarctic Circumpolar Current. These areas are characterized by a positive correlation between mesoscale perturbations in the curl of the surface currents and the wind curl. The coupling coefficients are spatially non-uniform and show a pronounced seasonal cycle. The positive feedback of mesoscale current features on the near-surface wind acts in opposition to their damping effect on the wind stress. A tentative incorporation of this feedback in the surface stress formulation of an eddy-permitting global ocean-only model leads to a gain in the kinetic energy of up to 10 %, suggesting a fundamental shortcoming of present ocean model configurations.

    Aspects of air-sea interaction in atmosphere-ocean models (2018)
    In:  (PhD/ Doctoral thesis), Christian-Albrechts-Universität Kiel, Kiel, Germany, 125 pp
    Details
    Publication Date: 2021-02-08
    Description: Air-sea interaction is governed by complex processes acting on a variety of spatial scales, which makes it extremely difficult to correctly represent these in ocean and atmosphere general circulation models. In this thesis some aspects of the representation of air-sea interaction in both forced ocean-only and coupled atmosphere-ocean models are being discussed from a new angle. Models of coarse and eddying resolution were used to demonstrate the effect of shortcomings and to present possible solutions to overcome these. Particular attention was paid to improving ocean hindcasts and the effect of mesoscale ocean features.

    Publication Date: 2023-11-08
    Description: Folge 4 des Magazins GEOMAR.tv begleitet das Forschungsschiff METEOR auf seiner Jubiläumsfahrt in den Indischen Ozean. Vor Island ziehen Geologen des GEOMAR Bohrkerne aus dem Meeresboden, um mehr über Vulkanausbrüche in der Vergangenheit zu erfahren -- als Basis für Vorhersagen zukünftiger Eruptionen. Teilnehmer des Programms GAME untersuchen, welche Auswirkungen Mikroplastik auf marine Lebewesen hat. Außerdem: Ein Besuch im Aquarium des GEOMAR, das neue Blogportal oceanblogs.org, Artenvielfalt an Kalten Quellen am Meeresboden und das GEOMAR beim Fest zum Tag der Deutschen Einheit in Stuttgart.
