Association of solar activity with cosmic ray intensity during rising phase of solar cycle 24
CM Tiwari, Nidhi Bagga
We have studied the correlative relationship of the recorded time series of cosmic ray intensity and solar activity parameters during rising phase of solar cycle 24. The monthly and annual mean values of cosmic ray intensity counts have been used. The monthly mean values of sunspots numbers, solar flux (2800 MHz) and solar flare index have been used as solar activity parameters. The behaviour of cosmic ray intensity (solar cycle 24) with solar parameters have been studied by using running cross-correlation method. Cosmic ray neutron monitor intensities at Oulu and Climax were well anti-correlated with sunspots numbers but highly correlated sunspots number with solar flux (2800 MHz) and solar flare index are negative correlated with cosmic ray counts. A possible application of the results to space physics is discussed.
