This paper uses two simple variational data assimilation problems with the 1D viscous Burgers' equation on a periodic domain to investigate the impact of various diagonal-preconditioner update and scaling strategies, both on the limited-memory BFGS (

This paper focuses on Intensive Observation Period 17 of the Fronts and Atlantic Storm-Track EXperiment (FASTEX): the FASTEX special soundings obtained during that period are added to the conventional dataset and assimilated with a 4-dimensional vari

In the context of the FASTEX (Fronts and Atlantic Storm-Track EXperiment), this paper presents a number of tests and validations of the four-dimensional variational (4D-Var) data assimilation system under development at Meteo-France, over the Intensi

The incremental approach provides an approximate solution to four-dimensional variational data assimilation (4D-Var) at a reasonable CPU cost. An extension of this approach is studied, namely the multiple-truncation incremental technique, and is comp

The problem of time-continuous meteorological data assimilation is addressed. An optimal control method is proposed and studied for a simple well-posed 2D atmospheric model and continuous in time and space observations. An existence result for the op

Based on the assumption of small parameter variations a sensitivity–based analysis method is proposed for the computation of the steady–state mismatch deviations of periodic and quasi-periodic circuits. Unlike classical Monte-Carlo or worst-case

Great efforts have been made to search for enhanced semi-empirical forms of the bridge function b appearing in disordered condensed matter problems which are solved using the integral equation method. Currently, parameterized forms of the bridge func
