Effects of simulated natural variability on Arctic temperature
(American Geophysical Union, 2005-09-23)
A five-member ensemble with a coupled atmospheresea ice-ocean model is used to examine the effects of natural variability on climate projections for the Arctic. The individual ensemble members are initialized from a 300 ...
Large-Scale Atmospheric Circulation Variability and its Impacts on the Nordic Seas Ocean Climate - a Review. In: The Nordic Seas: An Integrated Perspective
(American Geophysical Union, 2005)
The large-scale atmospheric circulation and its impacts on the Nordic Seas ocean climate are reviewed. The dominant factors for the atmospheric variability are the Icelandic low and the Azores high, determining the strength ...
Using the Extended Kalman Filter with a Multilayer Quasi-Geostrophic Ocean Model
(American Geophysical Union, 1992-11-15)
The formulation of the extended Kalman filter for a multilayer nonlinear quasi-geostrophic ocean circulation model is discussed. The nonlinearity in the ocean model leads to an approximative equation for error covariance ...
Circulation and transformation of Atlantic and Arctic water masses in climate models
(The University of Bergen, 2011-12-09)
Ocean heat transport and associated heat loss to the atmosphere contributes significantly to the anomalously mild climate of northwestern Europe and its variability. In this thesis, the circulation and transformation of ...
Multisensor approach to automated classification of sea ice image data
(IEEE Geoscience and Remote Sensing Society, 2005-07)
A multisensor data fusion algorithm based on a multilayer neural network is presented for sea ice classification in the winter period. The algorithm uses European Remote Sensing (ERS), RADARSAT synthetic aperture radar ...
The Effect of Diapycnal Mixing on the Ventilation and CFC-11 Uptake in the Southern Ocean
(Science Press, 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). ...
On the Velocity Gradient in Stably Stratified Sheared Flows. Part 2: Observations and Models
Observations of the dependence of the dimensionless wind speed gradient φm as a function of the Monin–Obukhov stability parameter z/Lo under strong stability diverge from results of large-eddy simulation (LES) modelling. ...
Magnitude and Origin of the Anthropogenic CO2 Increase and the 13C Suess Effect in the Nordic Seas since 1981
This study evaluates the anthropogenic changes of CO2 (∆Cant) and δ13C (∆δ13Cant) in the Nordic seas, the northern limb of the Atlantic Meridional Overturning Circulation, that took place between 1981 and 2002/03. The ...
Cover ERS-1/2 SAR monitoring of dangerous ice phenomena along the western part of Northern Sea Route
(Taylor & Francis, 1997-08-01)
Intermediate water from the Greenland Sea in the Faroe Bank Channel : spreading of released sulphur hexafluoride
The Faroe Bank Channel is the deepest passage for dense water leaving the Nordic Seas into the North Atlantic. The contribution to this part of the Greenland-Scotland Overflow by intermediate water from the Greenland ...
