Semblance study of force-field and convection-diffusion solutions with observations of solar magnetic phenomena

Summary

A quantitative model is proposed to evaluate differences in transport equation solutions and Local Interstellar Spectra (LIS) for Cosmic Ray (CR) modulation using the semblance method.

Highlights

• The semblance method compares transport solutions and LIS, providing insights into CR behavior.
• The model identifies a correlation between the modulation factor and sunspots, and an anti-correlation with the mean magnetic field.
• The force field solution shows stronger semblance values, aligning better with neutron detector data.
• LIS models by Lagner, Potgieter & Webber (2003), and Ghelfi et al. (2017) are most consistent.
• The Garcia-Munoz et al. (1975) LIS reveals notable variations.
• The study underscores the semblance method as a critical tool for comparing CR modulation models.
• The proposed model advances predictive models of cosmic ray behavior influenced by solar and interstellar conditions.

Key Insights

• The semblance method is a valuable tool for comparing different transport equation solutions and LIS, allowing for a more comprehensive understanding of CR modulation.
• The correlation between the modulation factor and sunspots suggests that solar activity plays a significant role in shaping CR behavior.
• The anti-correlation between the modulation factor and the mean magnetic field indicates that the magnetic field's influence on CR modulation is more complex than previously thought.
• The force field solution's stronger semblance values suggest that it is a more accurate representation of CR modulation.
• The consistency of the Lagner, Potgieter & Webber (2003), and Ghelfi et al. (2017) LIS models indicates that these models are more reliable for predicting CR behavior.
• The notable variations in the Garcia-Munoz et al. (1975) LIS model highlight the need for further refinement of this model to accurately predict CR behavior.
• The proposed model's ability to advance predictive models of cosmic ray behavior influenced by solar and interstellar conditions has significant implications for our understanding of the universe.
