Description
The relationship between the Wolf number and rainfall in Sydney is investigated via statistical analysis. Power spectra and cross-correlations reveal a small seasonal relationship since ~1950 (when evidence suggests a climate shift took place). A weak correlation is found for summer whilst a stronger anti-correlation exists throughout the remainder of the year. A hypothesis is presented to explain this observation. An analysis, using the alternating conditional expectations (ACE) algorithm, of the predictive power of the Wolf number is compared to that of the Southern Oscillation Index (SOI) – which describes a global variable known to influence rainfall in the eastern states of Australia. The two are found to be similarly effective but this efficacy is low.
