Reduced-order 4D-Var: a preconditioner for the Incremental 4D-Var data assimilation method
This study demonstrates how the incremental 4D-Var data assimilation method can be applied efficiently preconditioned in an application to an oceanographic problem. The approach consists in performing a few iterations of the reduced-order 4D-Var prior to the incremental 4D-Var in the full space in order to achieve faster convergence. An application performed in the tropical Pacific Ocean, with ...
متن کامل13: 4D-Var Data Assimilation for Navy Mesoscale NWP
The long-term goal of this Rapic Transition Process (RTP) project is to provide the warfighter with superior battlespace environmental awareness in terms of high fidelity four-dimensional (4D) depiction of the regional/mesoscale atmospheric states. This situational awareness is a key aspect of information superiority in the DoD’s strategic plan to ensure battlespace dominance in the 21st centur...
متن کاملStrategies for processing images with 4D-Var data assimilation methods
Data Assimilation is a well-known mathematical technic used, in environmental sciences, to improve, thanks to observation data, the forecasts obtained by meteorological, oceanographic or air quality simulation models. It aims to solve the evolution equations, describing the dynamics of the state variables, and an observation equation, linking at each space-time location the state vector and the...
