Keywords:extreme weather events, global warming, climate change, Event Attribution

Japan has experienced several extreme weather events, such as heat waves, heavy precipitation, and heavy snowfall, under the progress of global warming. The event attribution (EA) researches can evaluate the impact of historical global warming on the extreme weather events. There are two EA methods, the risk-based EA and story-line EA, evaluate the impacts of global waming probabilistically and quantitatively, respectively. We will show the examples of EA studies focusing on heavy precipitatation and heat waves in 2018, Typhoon Hagibis in 2019, heat waves in 2022 and 2023, quasi-stationary band-shaped convective precipitation system (senjo-kousuitai), and heavy precipitation occurred in Noto peninsula in 2024. Lastly, we will introduce the futhure changes in heavy precipitation due to global warming projected by the high-resolution regional clomate model.
