A lot of advanced simulation studies are being conducted by high performance supercomputers, such as K computer and Earth Simulator, in various fields including meteorology. The high performance supercomputers enable us to conduct numerical simulations and data assimilation of observation big-data (huge high-density and high-frequency data) with a few orders of magnitude higher resolutions and ensemble numbers than those with the previous supercomputers. In addition, the post-K computer, Fugaku will be available as a successor of K, and studies for the Fugaku computer are in progress. At this session, we comprehensively pick up the topics in the Atmospheric and Hydrospheric Sciences Sessions of the 2020 Union Meeting that comprise the atmospheric, oceanic and land sciences. This session aims to promote recent studies related to the issues on high performance computing in weather, climate, and environmental studies using the K computer and other supercomputers, study plans using the Fugaku computer, and to enhance discussions on future directions of numerical simulations in meteorology.
