In this work a class of algorithms for estimation of time-varying coefficients of Lorenz-like systems is presented. The main application is aimed at the prediction of weather scenarios providing a solution based on Identification and the Theory of Bifurcation. The estimation algorithms are based on a gradient law and faced the problem of different order of magnitudes in the regression elements and of unbounded time-varying coefficient with the use of normalization. Numeric simulations show that qualitative predictions of future behavioral evolution can precisely be made with relatively larger anticipation in time than in the case done from the analysis of realizations.
