Dynamics and Predictability of the Extreme Extratropical Cyclone Nina
(Master thesis, 2016-06-01)An extreme extratropical cyclone struck western Norway at 12 UTC 10 January 2015 causing significant damage to property due to extreme winds. The European region has a history of being struck by extreme cyclones that cause ... -
The dynamics of a barotropic current impinging on an ice front
(Journal article; Peer reviewed, 2022)The vertical front of ice shelves represents a topographic barrier for barotropic currents that transport a considerable amount of heat toward the ice shelves. The blocking effect of the ice front on barotropic currents ... -
Dynamics of a CO2-seawater interface in the deep ocean
(Journal article, 2005)A trough filled with liquid CO2 located at 3940 m depth has been used as a model system for CO2 deposition on the seafloor. To study the intrinsic properties of the interface between CO2 and seawater a wave maker was used ... -
Dynamics of anomalous stratospheric eddy heat flux events in an idealized model
(Journal article; Peer reviewed, 2020-05-28)Extreme stratospheric eddy and sudden stratospheric warming (SSW) events both involve anomalous stratospheric eddy heat flux. The cause of the anomaly has been hypothesized to be due to tropospheric or stratospheric dynamics. ... -
Dynamics of concurrent and sequential Central European and Scandinavian heatwaves
(Journal article; Peer reviewed, 2020)In both 2003 and 2018 a heatwave in Scandinavia in July was followed by a heatwave in Central Europe in August. Whereas the transition occurred abruptly in 2003, it was gradual in 2018 with a 12-day period of concurrent ... -
The Dynamics of the East Madagascar Current System and Its Influence on the Biological Production Associated to the Shelf - An Observational Study
(Master thesis, 2011-06-01)The dynamics of the East Madagascar Current (EMC) system, and its influence on the biological production associated to the shelf, is studied by using cruise-data collected onboard the Norwegian R/V. Dr. Fridtjof Nansen ... -
Early detection of anthropogenic climate change signals in the ocean interior
(Journal article; Peer reviewed, 2023)Robust detection of anthropogenic climate change is crucial to: (i) improve our understanding of Earth system responses to external forcing, (ii) reduce uncertainty in future climate projections, and (iii) develop efficient ... -
The Earth system model CLIMBER-X v1.0 - Part 2: The global carbon cycle
(Journal article; Peer reviewed, 2023)The carbon cycle component of the newly developed Earth system model of intermediate complexity CLIMBER-X is presented. The model represents the cycling of carbon through the atmosphere, vegetation, soils, seawater and ... -
The East Greenland Current studied with CFCs and released sulphur hexafluoride
(Journal article, 2005-03)The distribution and evolution of water masses along the East Greenland Current (EGC) from south of the Fram Strait to the Denmark Strait were investigated using chlorofluorocarbons (CFCs) and the released tracer sulphur ... -
The East Greenland Current: Structure and Variability

Eastern boundary circulation and hydrography off Angola. Building Angolan oceanographic capacities
(Peer reviewed; Journal article, 2018-09-06)The eastern boundary region off Angola encompasses a highly productive ecosystem important for the food security of the coastal population. The fish-stock distribution, however, undergoes large variability on intraseasonal, ... -
Eddies and the Distribution of Eddy Kinetic Energy in the Arctic Ocean
(Journal article; Peer reviewed, 2022)Mesoscale eddies are important to many aspects of the dynamics of the Arctic Ocean. Among others, they maintain the halocline and interact with the Atlantic Water circumpolar boundary current through lateral eddy fluxes ... -
Eddy Structure and Dynamics in the Mozambique Channel
(Master thesis, 2010-06-01)Abstract The Mozambique Channel circulation is dominated by a sequence of southward migrating cyclonic and anticyclonic eddies and previous studies have been done to investigate the flow, the variability and nature of the ... -
Eddy-resolving simulations of the Fimbul Ice Shelf cavity circulation: Basal melting and exchange with open ocean
(Peer reviewed; Journal article, 2014-10)Melting at the base of floating ice shelves is a dominant term in the overall Antarctic mass budget. This study applies a high-resolution regional ice shelf/ocean model, constrained by observations, to (i) quantify present ... -
Effect of critical latitude and seasonal stratification on tidal current profiles along Ronne Ice Front, Antarctica
(Journal article, 2006-03-30)The ice front region of Ronne Ice Shelf lies near the critical latitude of the semidiurnal M2 tide, the principal tidal constituent in the southern Weddell Sea. Here the Coriolis frequency almost equals the M2 tidal ... -
The Effect of Diapycnal Mixing on the Ventilation and CFC-11 Uptake in the Southern Ocean
(Advances in Atmospheric Sciences;21(5), Journal article, 2004-03-04)The Miami Isopycnic Coordinate Ocean Model (MICOM) is used to investigate the effect of diapycnal mixing on the oceanic uptake of CFC-11 and the ventilation of the surface waters in the Southern Ocean (south of 45°S). Three ... -
The effect of moisture transport variability on Ethiopian summer precipitation
(Peer reviewed; Journal article, 2013-12)The main rainy season in Ethiopia occurs during the northern hemisphere summer, when air masses carrying moisture from the Indian Ocean, the Gulf of Guinea, the African continent, the Red Sea, and the Mediterranean Sea, ... -
The Effect of Sea Surface Temperature Fronts on Atmospheric Frontogenesis
(Journal article; Peer reviewed, 2021)It is thought that the sensible heat fluxes associated with sea surface temperature (SST) fronts can affect the genesis and evolution of atmospheric fronts. An analytic model is developed and used to explore this idea. The ... -
