摘要:Abstract(#br)This paper introduces the Sobol’ indices approach for global sensitivity analysis (SA), in the context of marine biogeochemistry. Such an approach is particularly well suited for ocean biogeochemical models, which make use of numerous parameters within large set...

摘要:Two years of altimetric data from Topex/Poseidon (October 1992–September 1994) and ERS-1 (October 1992–December 1993) were assimilated into a numerical model of the North Atlantic. The results of these simulations are analysed in the Azores region to assess the performance o...

摘要:Abstract(#br)Two years of altimetric data from the Geosat satellite and one year from Topex/Poseidon were assimilated into a numerical ocean circulation model of the North Atlantic. The results of these simulations were used to compute statistics concerning the movements of ...

摘要:Abstract(#br)This paper emphasizes the peculiar role of characteristic variables in the design of open boundary conditions (OBCs). It is shown that local OBCs leading to positive results in previous comparative studies do fulfil two requirements: they make use of incoming charact...

摘要:Abstract(#br)This paper presents a reduced-order approach for four-dimensional variational data assimilation, based on a prior EOF analysis of a model trajectory. This method implies two main advantages: a natural model-based definition of a multivariate background error covarian...

摘要:Abstract(#br)Several methods for specifying boundary conditions at the limits of a regional model are compared. The methods investigated are those using clamped and radiation boundary conditions, one-way and two-way nesting in a model for a more extensive area, and “full” co...

摘要:Abstract(#br)In this paper we examine the application of a domain decomposition method to the solution of Poisson and Helmholtz equations often involved in the oceanic models. By studying a theoretical convergence rate of the method in the case of two subdomains (which can be gen...

摘要:The deep polar ice cores provide reference records commonly employed in global correlation of past climate events. However, temporal divergences reaching up to several thousand years (ka) exist between ice cores over the last climatic cycle. In this context, we are hereby in...
