By using the daily meteorological observation data from 4 stations of Hulunbuir from 1972 to 2013, two kinds of daily comprehensive meteorological drought indexes (MCI and CI) on yearonyear basis are calculated, and the drought days, drought intensity, drought duration, and typical drought processed, as well as the coincidence degree with actual condition, are calculated and compared by means of the two kinds of drought indexes.The results show that for not considering the weight of daily precipitation, there are more jumps in CI than in MCI; in MCI, the 150day SPI (Standardized Precipitation Index) is introduced and the weights of the winter and summer precipitation are considered to avoid the overweight problem of the drought index for Hulunbeir winter and early spring droughts. In combination with actual climate and actual situation of drought disasters in Hulunbeir, the results indicate that MCI is closer to the reality and more suitable for practical applications.
