Seeking a Research Scientist or Postdoctoral Researcher (R-CCS2030)

Laboratory

Computational Climate Science Research Team
RIKEN Center for Computational Science
(Team Leader: Hirofumi Tomita)

Pioneering Project (FY2020-FY2024)

RIKEN started a new pioneering project titled “Prediction for Science” in April 2020 for 5 years. The researcher under this call will be based in Computational Climate Science Research Team at Kobe, to work together with various laboratories in theory and applications and will bring synergy and fusion among different areas, so that we pioneer a general theory of prediction, the first step toward the whole new world of “Prediction Science”. To achieve the ambitious goal, the researcher under this call is able to spend an extended period for several months or longer in some of the participating laboratories as shown below and to work on the synergy and fusion among theory.

Research Field

RIKEN Center for Computational Science (R-CCS), led by Center Director Satoshi Matsuoka, is an international research center in high performance computing and computational science in Japan. Our objectives are to investigate “the Science of (high performance) computing, by computing, and for computing”, to research and develop our technologies (R-CCS technology) and software (R-CCS software), which we consider our core competence, in order to produce world-leading scientific and engineering results for use in Japan as well as globally.

Also, R-CCS started operating Japan’s national flagship supercomputer Fugaku, as a shared national facility to support a wide range of research activities since 2021.

Our laboratory is developing a model library that is the basis of meteorological and climate models in collaboration with Mathematical Climatology Laboratory in Cluster for Pioneer Research. With the advent of large-scale computers such as K Computer, it has become possible to simulate the global atmosphere using a cloud-resolving model with a grid-sized of less than 1 km. On the other hand, the global cloud-resolving model cannot directly calculate phenomena smaller than the grid size, though they affect atmospheric motion and cloud formation. In order to reduce the uncertainty of the calculation results associated with this problem, we have to sophisticate models further. In the future, it is expected that the uncertainty due to the difference in modeling will be reduced by converging to a global eddy-resolving model, which is based on a more reliable guiding principle. However, there is still a long way to go. We must overcome the following issues: Development of new models of phenomena in the actual atmosphere and ocean and their computational schemes, development of fast computational algorithms, development of post-processing libraries for analysis of large-scale computations, and so on. To achieve them, we are starting to develop a new method of modeling that incorporates data science. At the same time, by large-scale numerical experiments using these models on Fugaku, we are tackling multiple scientific tasks such as the research for the hierarchical structure of clouds and climatological multiple equilibrium solutions under ideal conditions, and regional climate research for actual phenomena.

Job title and Job description

Job title

Research Scientist or Postdoctoral Researcher: 1 position

Job description

So far, meteorological and climate models have been built primarily by a deductive approach. In this project, in addition to this method, we will infer the guiding principle of the model by an inductive approach that makes full use of data science based on a large amount of observation and calculation data. In this way, we will seek new meteorological and climate modeling methods by integrating the two ways. Through this research, we will work closely with RIKEN's internal and external partners, including other fields. Finally, we will combine computational science as the third paradigm and data science as the fourth paradigm, and aim to establish "Prediction Science" as the fifth paradigm. In order to demonstrate the effectiveness of the new modeling technology, we aim to understand the mechanism of climate phenomena by making full use of large-scale computers. One of our major goals is to expand the results obtained from new modeling methods to fields other than meteorology and climatology.
