Abstract: An agro-meteorological drought index suitable for various situations is impossible. Any drought index has its limitations. Many researchers revised and improved the regular agro-meteorological drought index in their studies in order to get more accurately describe of the occurrence of drought. In this study, basic principles and revised applications of three frequently-used drought indices are introduced. They are precipitation anomaly percentage, Palmer drought index and CI drought composite index. The purpose of this study is providing an idea for the further studies.
