Precipitation and Temperature Climatologies over India: A Study with AGCM Large Ensemble Climate Simulations

This study investigated the precipitation and temperature climatologies over India from large ensemble (100 members) historical climate simulations in two recent past periods (1951–1980 1981–2010). The main focus was to statistically examine usefulness of such by discussing (1) their distribution patterns, (2) annual cycle climatologies, (3) frequency distributions potential spatial patterns variability. We applied empirical orthogonal function understand characteristics normal probability investigate frequency. Results indicated good agreements these ensembles simulated results with observation Indian region. amount many regions is decreased entire increased 1981–2010 compared that 1951–1980. precipitations a decrease amounts June through October, while an increase for months November January. during July March. monthly temperatures indicate overall period. reason period attributed relative humidity cloud together weaker vertical velocity region 1981–2010. Overall validates assessment suggests datasets may be used various purposes related weather India.
