Climate of the 20th and 21th century simulations by a 60-km mesh global atmospheric model

Climate of the 20th and 21th century simulation was conducted with a 60-km mesh global atmospheric model (MRI-AM60km) from year 1872 to 2099. For the historical simulation of 20th century, the model was forced with observed historical Sea Surface temperature (SST) and sea ice (HadISST1). For the 21th century, the model was forced with SST and sea ice projected by a multi-model ensemble of Atmosphere-Ocean General Circulation Models (AOGCMs) for the Coupled Model Intercomparison Project phase 3 (CMIP3). The A1B emision scenario is assumed. Time variations of global and hemisphere average land surface air temperatures are reasonablely well simulated in the 20th century. The number of simulated tropical cyclone in the whole globe has decreasing trend throughout the 20th and 21th century. Precipitation of East Asian summer monsoon in the end of 21th century increases relative to the end of 20th century, whereas precipitation decreases in the end of 19th century.
