What is Signatures of Universal Characteristics of Fractal Fluctuations in Global Mean Monthly Temperature Anomalies about?

Selfsimilar space-time fractal fluctuations are generic to dynamical systems in nature such as atmospheric flows, heartbeat patterns, population dynamics, etc. The physics of the long-range correlations intrinsic to fractal fluctuations is not yet identified. It is important to quantify the physics underlying the irregular fractal fluctuations for predictability studies. A general systems theory for fractals visualizes the emergence of successively larger scale fluctuations to result from the space-time integration of enclosed smaller scale fluctuations. The model predictions are as follows. The probability distribution and the power spectrum for fractal fluctuations is the same inverse power law function incorporating the golden mean. The predicted distribution is close to the Gaussian distribution for small-scale fluctuations but exhibits fat long tail for large-scale fluctuations with higher probability of occurrence than predicted by Gaussian distribution. Since the power (variance i.e. square of eddy amplitude) spectrum also represents the probability densities as in the case of quantum systems such as the electron or photon, fractal fluctuations exhibit quantumlike chaos.
