Applications of nonlinear time series analysis in solar physics
Abstract
We applied methods of nonlinear time series analysis to different aspects of the solar phenomenology, as the solar cycle, the solar granulation and solar radio bursts. The methods include tests for deterministic chaos hidden in the data, as the determination of global attractor dimensions. However, in solar physics we deal with "real world" time series, which hardly allow to detect pure determinism. Therefore we also applied tools, which enable to cope with non-stationarities in the data and provide statistical significance even in cases where the existence of low-dimensional chaos cannot be established, like local dimension estimations and recurrence plots. The relevant methods are described with application to different solar time series.
