Table 1
A linear correlation coefficient, r, and the single-sided chance probability that |r| has an equal or larger value than its observed value in the null hypothesis, P, in parenthesis. This shows the relationship between (1) the total sunspot area ((A_N+A_S)), (2) the solar North-South asymmetry ((A_N,=−A_S)/(A_N+A_S)), and (3) the SOI and positions of tropical cyclone occurrence/development and other cyclone characteristics
