About Our Research

The World Climate Research Program (WCRP) strongly advocates actionable climate science, which connects research results with society. In Japan, the national Climate Change Projection Dataset forms the basis for climate change measures; updates will be made on a relatively regular basis starting 2022 and there are demands for different types of data (see figure). In Research Area 3, we aim to create regional climate projections with increased accuracy and diversity and reduced uncertainty to support local government decision-making. Data application will be expanded to include the fields of hydrology and water resources, and our results can be used for the management of water use, fisheries, aquaculture, and flood control. We will develop a model system that includes sophisticated regional climate models, global models with ocean effects, and enhanced ocean information around Japan. In addition, we will focus on regional climate, extreme events, and data application across different domains of the society through the following activities.

(1) To stimulate the application of research results across the society, we will produce information that meets users’ needs by increasing model sophistication, generating marine data, and improving reproducibility in the modeling of extreme phenomena and our understanding of climate mechanisms.

(2) To further facilitate the use of research results, we will engage in two-way communication with users and establish a user-friendly information provision system in cooperation with various domestic organizations, including DIAS, which is responsible for the system.

(3) To contribute to the development and implementation of climate change adaptation measures in vulnerable regions overseas that are similar to Japan and are facing increasing risks of heavy rains, floods, and storm surges, we will create highly accurate climate forecast datasets for these regions in collaboration with researchers in the regions.
