A research group led by Prof. Nobuhito Mori conducted a large number of high-resolution climate simulations covering all of Japan, based on the “d4PDF: large-ensemble and high-resolution climate simulations for global warming risk assessment”.
The paper “Identifying robust changes of extreme precipitation in Japan from large ensemble 5-km-grid regional experiments for 4K warming scenario” analysis showed that the frequency and intensity of once-every-50-year heavy rainfall events and linear precipitation zones in Japan will increase as global warming progresses, as will the heavy rainfalls associated with typhoons.
This data will be made public through the Data Integration and Analysis System (DIAS). The data will be useful for analysis of future disaster prevention in Japan against extreme weather events such as heavy rainfall but also extreme heat and heavy snowfall. This data will also be useful for the formulation of global warming adaptation measures.
The research results were published in the international “Journal of Geophysical Research-Atmosphere” on 19 September 2023.
