Intermittency and Turbulent Spectra of Solar Activity: A Five-Year Analysis during Solar Cycle 25

Abstract

This paper investigates the intermittent nature and turbulent spectra of solar wind fluctuations during the critical five-year period of Solar Cycle 25 (2019–2024). Using data from ACE, WIND, Parker Solar Probe, and Solar Orbiter, this study identifies patterns of turbulence and intermittency through structure function analysis, scaling exponents, and multifractal modeling. Key events, such as the X-class flare on October 24, 2024, are analyzed to illustrate real-time impacts of turbulent phenomena. Findings highlight the dynamic interplay between solar magnetic activity, proton density fluctuations, and magnetic cloud passage, offering implications for modeling heliospheric conditions and improving space weather resilience.
