| Scope |
The aim of this session is to introduce the frontiers of the research areas covered by the Atmospheric and Hydrospheric Sciences Section. In recent years, both the frequency and intensity of extreme heat events have been increasing, and their occurrence involves the complex interaction of diverse processes across the atmosphere, hydrosphere, and land surface. In 2023 and 2024, unprecedented high temperatures were recorded globally and in Japan, prompting atmospheric and hydrospheric scientists to undertake investigations of these phenomena from multiple perspectives. In this lecture series, atmospheric science contributions will explore the multifaceted factors behind the extreme heat events of 2023 and 2024, both worldwide and in Japan. Topics include the influence of each ocean basin and land surface on the atmosphere, as well as the amplification of high temperatures due to anthropogenic external forcings. From the ocean science, topics such as possible influence of ocean variability on radiative balance, ocean heat uptake, and redistribution of heat will be provided to discuss the role of ocean in the extreme heat events in 2023 and 2024. From the hydrology, the topic of the impact of recent extreme high temperatures at land and sea surfaces is provided in the context of using water isotope ratio variations to understand the dynamics of the global water cycle, including precipitation formation. We look forward to active feedback and discussion from many related researchers.
