Testing for nonlinearity in weather records

1994 Physics Letters A  
Daily records of atmospheric surface pressure, temperature and geopotential heights of 500 hPa isobaric level were tested for nonlinearity, the necessary condition for deterministic chaos, using redundancy  ...  in the dynamics of the pressure recording, however, no specific signatures of low-dimensional chaos were manifest.  ...  Simulation experiments, involving networks of coupled dynamical systems, related to the models studied in the atmospheric physics, could be of interest here.  ...

Synergy and redundancy in the Granger causal analysis of dynamical networks

Sebastiano Stramaglia, Jesus M Cortes, Daniele Marinazzo
2014 New Journal of Physics  
Second, our analysis applied to gene expression time series from HeLa culture shows that the underlying regulatory networks are characterized by both redundancy and synergy.  ...  Whilst we show that fully conditioned Granger causality is not affected by synergy, the pairwise analysis fails to put in evidence synergetic effects.  ...  The driving influence from the multiplet to x 5 detected by CGC vanishes at high coupling redundancy, both in the linear and nonlinear approach, due to the redundancy induced by synchronization.  ...
