Purpose of my Project

• I want to see how sunspots and storm intensities
  were related.
• If there was not much to find, I wanted to find
  out
• How each of the intensities were related to each
  other
• Along with how they related to the total number
  of storms and the average intensity during that
  year

Methodology

• Correlation Coefficient
• Are there any direct correlations?
• Periodograms
• Are there any frequencies that stand out?
• Crossspectral analysis
• Do any of the frequencies relate?
• If so, what are the phase angles?

Conclusion

• The correlation coefficient reveals no direct
  correlation between sunspots and intensity
• Despite this, the cross spectral analysis reveals
  that the sunspots and intensities have their
  largest peak at roughly the same frequency
  meaning that there could likely be some
  relationship
• The correlation coefficient reveals a good
  relationship between each intensity and the total
  number of storms
