Many studies have shown that global climate patterns can affect the precipitation around the world. Since the relationship between some climate patterns like, El Niño-Southern Oscillation (ENSO), Indian Ocean Dipole (IOD), Arctic Oscillation (AO) and Antarctic Oscillation (AAO), with the global precipitation is not constant, a systematic analysis of the influence of the climate patterns on precipitation anomaly over the world is necessary. This motivates our current study. The global precipitation data used are from the Global Precipitation Climatology Project (GPCP), and the study period is from 1979 to 2011. First, this study develops a model to simulate the precipitation anomaly around the world using four key climate pattern indexes (namely, ENSO, IOD, AO and AAO index). Second, this study explores the varying relationship between the climate patterns and the global precipitat. published_or_final_version
