Major achievements
Dr. Yukiko Imada has conducted research to investigate the mechanism of extreme weather events such as heat waves, heavy rainfall, and droughts using numerical models. In particular, she conducted pioneering research by investigating the predictability of ENSO which can trigger various extreme events and by developing and applying the event attribution, a new method to quantify the impact of global warming on the probability of occurrence of extreme weather events. A series of her studies that explicitly show the impacts of anthropogenic global warming on the probability of extreme heat and heavy rainfall events have attracted social attention and have been cited by the latest assessment report of the Intergovernmental Panel on Climate Change (IPCC). The database for Policy Decision making for Future climate change (d4PDF), to which she contributed as one of the main developers, is used in global warming adaptation studies and Japanese government flood control plan. She also contributes as a member of the committees of international research organizations, and is a leading researcher not only in Japan but also in the international community. For these reasons, Dr. Yukiko Imada is a worthy recipient of the Nishida Prize, which honors her international academic research.
