    Description: Seit mehreren Jahren untersuchen Umweltmeteorologen der Universität Trier arktische Klimasysteme. In dem bis 2016 verlängerten Kooperationsprojekt mit russischen und deutschen Wissenschaftlern analysieren Professor Günther Heinemann und seine Mitarbeiter die Prozesse der Meereisproduktion und des Eistransports in der sibirischen Laptev-See. Das TV-Regionalmagazin SAT1 LIVE hat die Trierer Forscher bei der Arbeit beobachtet. Der Klimawandel bedroht vor allem die Arktis und deren Eisflächen. Diese haben sich im Nordpolarmeer in den vergangenen 30 Jahren um 40 Prozent verringert. Doch wie wird das Eis überhaupt gebildet? Ein Forschungsteam der Universität Trier hat sich auf den Weg in die Arktis gemacht und dieses Phänomen untersucht.

    Katabatic winds and polynya dynamics at Coats Land, Antarctica (2014)

    Description: Mesoscale model simulations were conducted for the Weddell Sea region for the autumn and winter periods of 2008 using a high-resolution, limited-area, non-hydrostatic atmospheric model. A sea ice–ocean model was run with enhanced horizontal resolution and high-resolution forcing data of the atmospheric model. Daily passive thermal and microwave satellite data was used to derive the polynya area in the Weddell Sea region. The focus of the study is on the formation of polynyas in the coastal region of Coats Land, which is strongly affected by katabatic flows. The polynya areas deduced from two independent remote sensing methods and data sources show good agreement, while the results of the sea ice simulation show some weaknesses. Linkages between the pressure gradient force composed of a katabatic and a synoptic component, offshore wind regimes and polynya area are identified. It is shown that the downslope surface offshore wind component of Coats Land is the main forcing factor for polynya dynamics, which is mainly steered by the offshore pressure gradient force, where the katabatic force is the dominant term. We find that the synoptic pressure gradient is opposed to the katabatic force during major katabatic wind events.
