The portion of a daily rainfall to annual rainfall is a criterion to find the density of daily rainfall. If high its probable whole or almost all annual rain happened in just a few days. In other words if this is high the rain is of shower type and if it is low it was a normal rain in some days. This study analyses the rainfall density in Khorasan Razavi province stations. These stations include, Turbot Heydarieh, Turbot Jam, Sabzevar, Sarakhs, Quechan, Kashmar, Golmakan, Gonabad, Mashhad and Neyshaboor. The frequency analysis of the maximum rain is calculated by the density function. The data are fitted into distribution: Norman Logistic, Gamma, Exponential, Gamble and Wake-by and fair distribution can be determined according to the goodness of fit test.
