lt has been known for many decades that the appear-
ance of sunspots is roughly periodic, with an average
cycle of eleven years. Moreover, the incidence of solar
flares and the flux of solar cosmic rays, ultraviolet radia-
tion, and x-radiation all vary directly with the sunspot (5)
cycle. But after more than a century of investigation. the
relation of these and other phenomena, known collec-
tively as the solar-activity cycle, to terrescrial weather
and climate remains unclear. For example. the sunspot
cycle and the allied rnagnetic-polarity cycle have been (10)
linked to periodicities discerned in records of such vari-
ables as rainhll. temperature, and winds. lnvariably,
