Solar Activity Influence on the Climate Via Magnetic Turbulence

Abstract

Earth’s climate is determined by complex interactions among the Sun, oceans, atmosphere, cryosphere, land surface and biosphere. The Sun is the principal driving force for Earth’s weather and climate. The influence of solar activity on the Earth’s global surface is determined due to temperature variation, which in turn drives the instabilities and is expressed via turbulent effects. Standard approaches to identify such connections are often based on correlations between the appropriate time series. Here we present a novel method Granger causality, which can infer/detect relationships between any two fields. We compare Solar activity – climate connections via magnetic turbulence identified by correlation and Granger causality at different timescales.
