Graphical Abstract

Plain Language Summary: The performance of the Meteorological Research Institute-Atmospheric General Circulation model version 3.2 (MRI-AGCM3.2) in simulating precipitation is compared with that of state-of-the-art global atmospheric climate models. As for the global distribution of seasonal and annual average precipitation, monthly precipitation over East Asia, and the seasonal march of rainy zone over Japan, MRI-AGCM3.2 models perform better than or equal to other climate models.

Highlights:

• The 20-km mesh MRI-AGCM3.2 is the highest horizontal resolution climate model used in global warming projection.
• Higher horizontal resolution models are better than lower resolution models in simulating the global distribution of seasonal and annual precipitation (Fig. 1) and the global distribution of intense precipitation, and the local distribution of summer precipitation over East Asia.
