Calendar Singularities of Rainfall in Rhodesia

摘要

For each of 55 stations rainfall totals accumulated over periods varying between 20 and 71 years are examined for Rhodesia according to calendar date. The agreement as to which dates favor the most rain is remarkable. It is also shown that Salisbury and Bulawayo derive almost coincident peaks with rain falling in different years. Bowen's meteor hypothesis could be the explanation, especially as the area of southern hemisphere land is comparatively small, and interhemispheric exchange of air is fairly slow.
