A SUMMARY OF SECULAR VARIATIONS OF COSMIC RAYS

Journal Article · · J. Phys. Soc. Japan
OSTI ID:4755108
The secular or 11-year changes that occur in galactic cosmic rays are discussed and it is concluded that: (1) there is a large change during a solar cycle of the cosmic ray particles reaching the vicinity of the earth; (2) there is nearly in inverse relationship between general solar activity and cosmic ray intensity; (3) the lower energy particles are affected much more thatn those of higher energy; (4) throughout most of the solar cycle there exists a knee in the latitude curve at high altitudes; and (5) cosmic ray intensity is not exactly anticorrelated with general solar activity as measured by Zurich sunspot numbers but lags solar activity by 6 to 12 months.
