Response of Indian summer monsoon (ISM) to the historical data of 13 selected models of Coupled Model Inter-comparison Project Phase 5 (CMIP5) suite has been investigated by considering the annual precipitation cycle, spatial distribution of rainfall, monsoon index, and domain along with wavelet and empirical orthogonal function (EOF) analysis. The domain of interest focuses on an area between 5 degrees N to 45 degrees N and 45 degrees E to 95 degrees E. NCEP/NCAR reanalysis, Global Precipitation Climatology Project (GPCP) and CMPA dataset are utilized for the period from 1955 to 2004. When compared with the given models, MIROC stands out to be the best suited dataset for monsoon season in Indian subcontinent. An ensemble of all the models has also been considered, and it produces good spatial and temporal distribution maps. However, it is not able to capture the peak values. MIROC has its limitations in capturing average monthly precipitation rate and rainfall distributions when compared to the reference dataset. The representation of Indian summer monsoon rainfall simulation by MIROC suggests it to be considered more consistent for the rainfall simulation projections in this highly complex climate system. This makes it more suitable and reliable for near-term to century rainfall projections in Indian subcontinent.
