Drought as an integrated part of climate variability may be investigated through many different aspects. In this study severity, duration and frequency of meteorological drought were investigated in Borujerd station. In the first step, annual rainfall status of wet and dry year was determined by using deciles. Then transition probability matrix and equilibrium transition matrix were developed with using of Markov chain. In this next step, using Run theory and based on a selected truncation level, severity, duration and frequency of drought were calculated. Finally, probability of drought for the next 10 years was predicted via combination of Run theory and Markov chain
