Abstract: The formalism of irreversible thermodynamics is applied to the shallow water model. Entropy production and entropy flow terms are identified, describing the ways dissipation and exchange processes unfold in space and time. ...

Abstract: The different modes of the early stages of the response of a forecasting model to a small error in the boundary conditions are analyzed. A general formulation of the problem based on the use of Green?s functions is developed ...

Abstract: The global observational network is known to be highly inhomogeneous and fractally distributed in space. In this paper the spatial distribution of stations in a network is studied in connection with the type of dynamics ...

Abstract: A systematic formulation of model error is developed accounting for both its dynamical and probabilistic aspects. Some generic features, largely independent of the particular model under consideration, are brought out in ...

Abstract: The dynamical and probabilistic aspects of model error arising from the neglect of unresolved scales and the concomitant reduction of phase space dimensionality of a reference system are analyzed. A general expression of ...

Abstract: Traditionally, climate is defined by the properties of the averages of the meteorological fields over an appropriate time interval. In this paper the properties of the time-averaged observables of a red noise atmosphere ...

Abstract: The authors report a systematic study on the short and intermediate time predictability properties of a quasigeostrophic T21L3 model in which emphasis is placed on the role of the Lyapunov vectors in the growth patterns ...

Abstract: linear response theory of systems of interest in atmospheric and climate dynamics taking fully into account the nonlinearities of the underlying processes is developed. Under the assumption that the source of intrinsic ...

Abstract: The dynamical properties of forecasts corrected using model output statistics (MOS) schemes are explored, with emphasis on the respective role of model and initial condition uncertainties. Analytical and numerical ...
