Abstract : Three cosmic ray storms during the IGY, which differ as to the type, have been treated for a study of changes in the effective integral rigidity spectrum. The time dependence of the exponent gamma of the spectrum is illustrated for the rigidity region 11-18 GV with a time resolution of two hours. An analytical expression is given where changes in the effective integral spectrum are transformed into changes in the primary spectrum. The extreme values of these changes vary from one storm to another. An extension of the treatment to lower rigidities is discussed. (Author)
