Characteristics of occurrence of heavy rainfall such as this maximum rainfall in history are evaluated by return period which was estimated by extreme value statistics. In order to supplement existing extreme value statistics, frequency of heavy rain and periodicity were discussed based on theory of record breaking and spectrum analysis with actual measurement value of rainfall which observed in observatories of Kanto region, Abukuma river basin, Agano river basin and Fuji river basin in this study. Results of analysis from theory of record breaking, Average number of record breaking of each observation time of annual maximum rainfall in all observatories are within range of the theory and record of heavy rainfall were broken about 4times for 40years. On the other hand, results of spectrum analysis, Annual maximum 3 days rainfall has period of about from 5 years to 13 years at 32 of 38points for analysis in mountain area. Annual maximum 10 minutes rainfall and annual maximum 1 hour rainfall has period of about from 5 years to 8 years at 3 of 6points for analysis in plain area., 【査読有】}, pages = {51--57}, title = {大雨発生の周期性と発生頻度に関する研究}, volume = {16}, year = {2011}, yomi = {イトカワ, カズヒロ and アラカワ, タカシ and オカベ, マサト and ヤマダ, タダシ} }
