JpGU-AGU Joint Meeting 2017

convener:Hiromu Seko(Meteorological Research Institute), Takemasa Miyoshi(RIKEN Advanced Institute for Computational Science), Chihiro Kodama(Japan Agency for Marine-Earth Science and Technology), Masayuki Takigawa(Japan Agency for Marine-Earth Science and Technology), Chairperson:Hiromu Seko(Meteorological Research Institute)

The K computer (the fastest supercomputer in Japan) started in 2012 at RIKEN, and a lot of advanced simulation studies are being conducted in various fields including meteorology. The K computer enables us to conduct numerical simulations with an order of magnitude higher resolutions and ensemble numbers than those with previous supercomputers, data assimilations of observation big-data (huge high-density and high-frequency data), and new research areas emerge in meteorology. In addition, the post-K computer will be available in 2021 as a successor of K, and studies for the post-K computer have also started.

At the Atmospheric Science Session co-organized by the Meteorological Society of Japan, we comprehensively pick up these topics in the Atmospheric and Hydrospheric Sciences Session of this 2017 Union Meeting that enables to 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, and to enhance discussions on future directions of numerical simulations in meteorology.
