Abstract: The relationship between the long-term variation of the cosmic ray intensity and solar activity considering the different time lags, has been investigated during the period 1965 - 1994. Several aspects of the long-term variations of cosmic ray intensity have been studied, adopting the K-series analysis method, during the ascending and descending phases of four successive sunspot solar cycles (i.e. from 19 to 22). Correlative analysis is the basis and has been applied for several time intervals. On the overall correlative analysis it has been observed th at the second parts of ascending phase for sunspot cycles are more effective in producing the cosmic ray modulation. The accumulative results of these effects produce long-term trends in cosmic ray intensity.
