On the effect of a sill on dense water formation in a marginal sea
(Sears Foundation for Marine Research/Yale University, 2008-05)
The properties of water mass transformation in a semi-enclosed basin, separated from the open ocean by a sill and subject to surface cooling, are analyzed both theoretically and numerically using an ocean general circulation ...
Sequential data assimilation with a nonlinear quasi-geostrophic model using Monte Carlo methods to forecast error statistics
(American Geophysical Union, 1994-05-15)
A new sequential data assimilation method is discussed. It is based on forecasting the error statistics using Monte Carlo methods, a better alternative than solving the traditional and computationally extremely demanding ...
High northern latitude surface air temperature: comparison of existing data and creation of a new gridded data set 1900–2000
(Blackwell Publishing Ltd., 2008-03)
Detection, attribution and understanding of temperature changes in the high northern latitudes depend on constraining uncertainties and resolving apparent discrepancies in observational data sets. We quantitatively compare ...
North Sea circulation: Atlantic inflow and its destination
(American Geophysical Union, 2006-12-22)
This study investigates the Atlantic inflow to the North Sea; its variabil- ity, pathways and destination. Results from a numerical model show that the variability of Atlantic inflow is dependent on the inflow location. ...
Sensitivity of simulated wintertime Arctic atmosphere to vertical resolution in the ARPEGE/IFS model
(Springer Verlag, 2007-10-16)
The current state of the art general circulation models, including several of those used by the IPCC, show considerable disagreement in simulating present day high latitude climate. This is of major concern and reduces the ...
Semi-empirical Algorithm for the Retrieval of Ecology-Relevant Water Constituents in Various Aquatic Environments
(Molecular Diversity Preservation International (MDPI), 2009-03-10)
An advanced operational semi-empirical algorithm for processing satellite remote sensing data in the visible region is described. Based on the Levenberg-Marquardt multivariate optimization procedure, the algorithm is ...
The Influence of large convective eddies on the surface-layer turbulence
(Royal Meteorological Society, 2006-06)
Close to the surface large coherent eddies consisting of plumes and downdraughts cause convergent winds blowing towards the plume axes, which in turn cause wind shears and generation of turbulence. This mechanism strongly ...
Cover ERS-1/2 SAR monitoring of dangerous ice phenomena along the western part of Northern Sea Route
(Taylor & Francis, 1997-08-01)
Modes of the southern extension of the East Madagascar Current
Data sets from satellite observations and a nested high‐resolution model are used to study a source region of the Agulhas Current. Altimeter‐derived geostrophic surface currents are averaged over varying periods, providing ...
Universal Dependences between Turbulent and Mean Flow Parameters in Stably and Neutrally Stratified Planetary Boundary Layers
(Copernicus GmbH on behalf of the European Geosciences Union and the American Geophysical Union, 2006-05-08)
We consider the resistance law for the planetary boundary layer (PBL) from the point of view of the similarity theory. In other words, we select the set of the PBL governing parameters and search for an optimal way to ...
