                         nT for the period 1957-2008 has been compiled. The dependence of 
                         Dst(p) on the solar cycle and annual variation are studied in this 
                         paper. It is found that geomagnetic storm peak intensity 
                         distribution can be described by an exponential form, P(Dst(p)) 
                         approximate to 1.2e(-Dstp/34) where P is the probability of 
                         geomagnetic storm occurrence with a given value Dstp. The updated 
                         solar cycle and annual distribution of geomagnetic storms have 
                         confirmed the expected behavior. For the solar cycle variation, 
                         geomagnetic storms display a two-peak distribution, with one peak 
                         close to solar maximum and the other a few years later in the 
                         beginning of the declining phase. Geomagnetic storms follow the 
                         well-known seasonal variation of geomagnetic activity. More 
                         intense storms show a peak in probability occurrence in July, 
                         confirming previous observations. These results are of practical 
                         importance for space weather applications.",
