■Feasibility study on very-short-range severe weather prediction by big data assimilation
チームリーダー Takemasa Miyoshi Data Assimilation Research Team, RIKEN R-CCS
We will develop the LETKF ensemble data assimilation systems based on the SCALE model and Japan Meteorological Agency Nonhydrostatic Model (JMANHM) at a 100-m resolution, and will assimilate observation data from the phased array weather radars and next-generation geostationary satellite to prove the concept of big data assimilation for very-short-range severe weather prediction.

■Study on reproducibility of severe local storms by a super high resolution eddy resolving atmospheric model
チームリーダー Hirofumi Tomita Computational Climate Science Research Team, RIKEN R-CCS
The next generation atmospheric model SCALE-LES is under development, and will be used for simulations of local weather. In particular, we will perform simulations with grid spacing of less than 100 m to investigate reproducibility of local severe storms. This model will be used for the development of numerical weather prediction system with phased array weather radars and the next generation HIMAWARI satellite.

■Development of high-speed quality control and data processing techniques for phased array weather radar and Doppler lidar
チームリーダー Shinsuke Satoh Applied Electromagnetic Research Institute, NICT
The phased array weather radar produces 100 times larger data than conventional radars. On the other hand, appropriate signal processing is needed to remove various noises in the observed signals. We will develop a rapid signal processing system to remove noises and transfer the “Science Big Data” to the forecast center so that the data assimilation system can utilize the data in real time.

■Optimizing observation methods of phased array weather radar
チームリーダー Tomoo Ushio Faculty of System Design, Tokyo Metropolitan University
The X-band phased array Doppler radar has been installed to Osaka University Suita Campus in June 2012. TOSHIBA and Osaka University were commissioned by NICT for the development of the state-of-the-art weather radar with rapid scan capability. We will investigate the optimal operation methods for very-short-range severe weather prediction by testing various radar beam scheduling.

■Development of inter-job parallel communication system and observation data archiving/distributing system
チームリーダー Yutaka Ishikawa Exascale computing project, RIKEN R-CCS
Data assimilation system runs a numerical weather prediction model and a data assimilation program alternatingly, and communication between the two are designed to use the file system. However, it is necessary to communicate without disk I/O to perform real-time high-resolution data assimilation cycles every 30 seconds. We will develop a middleware to enable the programs to communicate directly without changing the current application programs.
We will also develop a rapid data transfer system between the observation sites and the computer center.
