Cometary dust and the rainfall singularity shift

Daily rainfall data for Sydney, Prague, and Moscow for singularities around May 26 and November 9 were examined by an autocorrelation method. Intervals between 2 and 7 days were used for the autocorrelation. In all three samples, the wider the interval used the later the date of the best autocorrelation. The shift is discussed from the point of view of the Bowen hypothesis on meteor-rainfall correlation. In addition, new results supporting the Bowen hypothesis and its new version (Bowen, 1987) on bacteria from space, published recently, are briefly discussed.
