Solar Flare Intermittency and the Earth's Temperature Anomalies

TL;DR

This study investigates the potential link between solar flare intermittency and short-term Earth's temperature anomalies by analyzing temperature data from 1856 to 2002, revealing a Lévy process component consistent with solar activity effects.

Contribution

It introduces a novel analysis combining diffusion scaling and entropy to identify solar flare effects in Earth's temperature records.

Findings

Presence of Lévy component in temperature data

Correlation between solar flare intermittency and temperature anomalies

Evidence of solar influence on short-term climate variability

Abstract

We argue that earth's short-term temperature anomalies and the solar flare intermittency are linked. The analysis is based upon the study of the scaling of both the spreading and the entropy of the diffusion generated by the fluctuations of the temperature time series. The joint use of these two methods evidences the presence of a L\'{e}vy component in the temporal persistence of the temperature data sets that corresponds to the one that would be induced by the solar flare intermittency. The mean monthly temperature datasets cover the period from 1856 to 2002.
