Using MSSA to determine explicitly the oscillatory dynamics of weakly nonlinear climate systems
Nonlinear Processes in Geophysics
This paper presents a statistical diagnostic to interpret the dynamics of nonlinear variability in models. It consists in applying the Multichannel Singular Spectrum Analysis to the variability of a suitable equation of a dynamical system. This method enables us to evaluate the sensitivity of the oscillatory features of a physical model to tendencies in its mathematical formulation. Hence, responses in amplitude and frequency are determined in the phase space of the model. The example ofdoi:10.5194/npg-12-807-2005 fatcat:limsygp3v5e2favnvurivfp5t4
