Abstract

Different analytical formulas of temporal evolution are compared for the deviation between twin integrations carried out with the same general circulation model, starting from neighbouring initial conditions. We propose a generalization of the error growth formulas of Lorenz (1982) and Dalcher and Kalnay (1987), and study a limit case corresponding to the Gompertz growth law. The use of the generalized formula allows us to show that the growth rate of small errors and the saturation rate are different characteristics. We compare the error growth parameters given by the different formulas in the spectral domain. The stability of the results is tested by examining the influence of different lengths of the series and of different weightings in the least squares fit. We provide an upper bound for dynamical predictability and propose a measure for the characteristic time interval during which most of the error growth occurs.
