Dispersion of monthly mean Wolf's numbers as a prediction index.
Abstract
It is shown that at the decreasing branch of the cycle the r.m.s. deviation of monthly mean Wolf's numbers from their smoothed values correlates with the height of the next maximum (the correlation coefficient is 0.649). This gives predicted W22 = 138±20.9.
