The number of discrete time variations of the Cosmic Rays Flux of different amplitudes

We study the number of discrete variations in the flux of Cosmic Rays, of the type of Forbush decreases using the data base of neutron monitors from the Bartol Observatory. In the data of a given station, the standard deviation (sigma) of CRF was first estimated. Then, decrements of the kind of Forbush decreases, whose amplitude was larger than 3 sigma were identified and included in a first sample. Also, two other samples, one with decrements larger than 5 sigma and another with decrements larger than 10 sigma were made. In these samples also Forbush decreases are included. Then, with each sample a cumulative distribution was made and the derivative of each distribution of them was computed. The cumulative distributions for different sigmas are compared to each other to see the input to the variation of Cosmic Rays flux of jumps of different values through different phases of the solar activity cycle. The derivatives correlate well with the Sun Spots Number through the cycle and in particular the jumps trace the two peaks at the maximum. These features and other seen in the derivative time curves of Cosmic Rys at other phases of the cycle are discussed.
