“…The agreement between the periodicity of the OCR variations and meteorological and climate responses on the 11-year and century time scales and indications for its agreement on the day-to-day time scale have been discussed in the literature for 30 years. The present situation is that while a number of authors have considered GCR, supplemented at times by high-energy solar protons, as plausible carriers of the solar variability [Ney, 1959;Markson, 1971Markson, , 1983Dickinson, 1975;Herman and Goldberg, 1978b;Lethbridge, 1981;Robie and Hays, 1982;Ely and Huang, 1987], this view has not yet been convincingly supported by detailed comparisons of time variations. While Lundstedt [1984] has made the claim that the well-known dip in VAI following SB crossings was caused by a decrease in GCR flux, Lastovicka [1987] has argued that this is not so, since the dip precedes the decrease.…”
