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

Summary

A quantitative model using the semblance method evaluates differences in transport equation solutions and Local Interstellar Spectra (LIS) for Cosmic Ray (CR) modulation. The model identifies correlations between modulation factors, sunspots, and mean magnetic fields.

Highlights

• A quantitative model is proposed to evaluate CR modulation using the semblance method.
• The model compares transport equation solutions and LIS.
• Correlations are found between modulation factors, sunspots, and mean magnetic fields.
• The force field solution shows stronger semblance values, aligning 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 semblance method is a critical tool for comparing CR modulation models.

Key Insights

• The proposed model provides a more precise predictive model of cosmic rays with solar activity, enabling better understanding of CR behavior.
• The force field solution is more compatible with neutron detectors data, offering minimal amplitude variations.
• The analysis of contained zeros confirms the hypothesis of correlation between sunspots and modulation phenomena, and anti-correlation between mean magnetic field and modulation phenomena.
• The LIS models by Lagner, Potgieter & Webber (2003), and Ghelfi et al. (2017) offer the most consistent results, making them suitable for further analysis.
• The Garcia-Munoz et al. (1975) LIS shows notable variations, indicating a need for further refinement or revision.
• The semblance method is a valuable tool for comparing CR modulation models, enabling the identification of correlations and anti-correlations between different phenomena.
• The model can be used to advance predictive models of cosmic ray behavior influenced by solar and interstellar conditions.
