Abstract
The phase changes of the annual and semiannual variations of the cosmic ray intensity through two solar cycles and its relationship to the 22‐year solar magnetic cycle have been observed and reported by us. The phase of the yearly cosmic ray modulation reverses at the reversals of the polarity of the solar polar magnetic fields. The significance of this effect cannot be dismissed on the basis of an analysis on an insufficient data set, in fact, during the period 1960–1975 used by Khor et al. [1979], the solar magnetic configuration is steadily the same except that for the 4 years 1972–1975, which, however, do correspond to a variable interplanetary magnetic dipolar configuration.Keywords
