Description
Our research focuses on the evolution of sheath regions, specifically analyzing the open solar flux (OSF) and total pressure among other variables. To identify the most relevant contributions to the sheaths, we separate the total pressure into plasma and magnetic pressure components. Utilizing the extensive dataset obtained from Larrodera and Temmer (2024), we perform a detailed statistical and comparative analysis to examine the evolution of these parameters across different solar cycles and heliocentric distances.
Our results reveal a significant decrease in both OSF and total pressure from solar cycle 23 to solar cycle 24. This decrease is particularly pronounced for total pressure, which is predominantly influenced by the magnetic pressure component. The observed trend allows us to explore potential correlations between these magnitudes, leading to the proposal of a mathematical relationship that describes their interdependence.
Furthermore, our findings suggest that the OSF plays a crucial role in defining the total pressure within sheath regions. By understanding these dynamics, we can better predict the behavior of ICMEs and their impact on space weather. This research contributes to a more comprehensive understanding of the variability and dynamics of ICME sheaths, with significant implications for space weather forecasting and modeling.
