By using of different indices of drought, calculated and analyzed different precipitation states. In all of stations, often years and in most of drought indices, all precipitation categories existed. By two ways, it proved that precipitation states, especially droughts, become independence from elevation. These two ways are, 1. Amount of drought indices regress and analyze with elevation, 2.
