Climate change in the North – past, present and future
(International Union of Geological Sciences (IUGS), 2008-03)
The Nordic countries have produced famous polar explorers and researchers who have generated climate research schools at a variety of locations. The dependence of these countries with respect to the lifelihood of their ...
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 ...
Sea Ice Monitoring by Remote Sensing
(The American Society for Photogrammetry & Remote Sensing, 2006)
Open Boundary Conditions for the Extended Kalman Filter With a Quasi-Geostrophic Ocean Model
(American Geophysical Union, 1993-05-18)
The formulation of consistent boundary conditions for the quasi-geostrophic (QG) model with an extended Kaiman filter in a data assimilation scheme is discussed. To form a well-posed boundary value problem for the QG model, ...
Application of a hybrid EnKF-OI to ocean forecasting
(Copernicus Publications on behalf of the European Geosciences Union, 2009-10-01)
Data assimilation methods often use an ensemble to represent the background error covariance. Two approaches are commonly used; a simple one with a static ensemble, or a more advanced one with a dynamic ensemble. The latter ...
Future climate change: Modeling and scenarios for the Arctic
Evaluating Global Ocean Carbon Models: The Importance of Realistic Physics
(American Geophysical Union, 2004-09-15)
A suite of standard ocean hydrographic and circulation metrics are applied to the equilibrium physical solutions from 13 global carbon models participating in phase 2 of the Ocean Carbon-cycle Model Intercomparison Project ...
Evaluation of ocean carbon cycle models with data-based metrics
(American Geophysical Union, 2004-04-02)
New radiocarbon and chlorofluorocarbon-11 data from the World Ocean Circulation Experiment are used to assess a suite of 19 ocean carbon cycle models. We use the distributions and inventories of these tracers as quantitative ...
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 ...
Cover ERS-1/2 SAR monitoring of dangerous ice phenomena along the western part of Northern Sea Route
(Taylor & Francis, 1997-08-01)
