| Abstract(in English) | Thunder records have been measured at Numazu near Mt.Fuji,and at Tubata and Shishiku Heights near Kanazawa.The following observational results are derived:(1)Thunder records are classified into three types.(2)The thunder rumbling for the long time more than 30 sec is observed in winter lightning.(3)The dominant frequency of power spectrum is 140 Hz on the average,and lowers with the propagating distance.(4)The lowering frequency results from the superposition and the attenuation of sounds in the propagating process. |
