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 ...
An intercomparison of large-eddy simulations of the stable boundary layer
(Springer Science (former Kluwer Academic Publishers), 2005)
Results are presented from the first intercomparison of Large-eddy simulation (LES) models for the stable boundary layer (SBL), as part of the GABLS (Global Energy and Water Cycle Experiment Atmospheric Boundary Layer ...

Heat in the Barents Sea: Transport, storage, and surface fluxes
(Copernicus Publications, 2010-01-11)
A column model is set up for the Barents Sea to explore sensitivity of surface fluxes and heat storage from varying ocean heat transport. Mean monthly ocean transport and atmospheric forcing are synthesised and force the ...
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, ...
The greater Agulhas Current system: an integrated study of its mesoscale variability
(The Institute of Marine Engineering, Science & Technology (IMarEST), 2008-02)
For the purpose of developing an operational oceanography system for the greater Agulhas Current regime, a high resolution Hybrid Coordinate Ocean Model (HYCOM) has been set in a nested configuration. The intense and complex ...
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 ...
Ocean data assimilation systems for GODAE
(The Oceanography Society, 2009-09)
Ocean data assimilation has matured to the point that observations are now routinely combined with model forecasts to produce a variety of ocean products. Approaches to ocean data assimilation vary widely both in terms ...
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 ...
