Tropical cyclones (TCs) cause severe disasters in many countries by torrential rainfall and destructive winds. Intense TCs caused severe damages in many areas of Japan recently; a record-breaking heavy rainfall occurred in western Japan due partly to Typhoon Prapirooon (2018), Kansai airport was forced to be closed by Typhoon Trami (2018), and Typhoon Faxai (2019) caused a long-term shut-down in Chiba prefecture. As the surface temperature of ocean, - the energy source of TC -, increases with global warming, the change of TC activity in the future warming climate is expected. Therefore, it is an urgent problem to obtain deeper understanding of mechanisms and associated phenomena on TC genesis, intensity, structure, and motion, more accurate mid- to long-term projections of the TC parameters, and advanced observations and better forecast of TC. The TC researches are important for disaster prevention as well as the academic development, and hence do contribute to the future progress of earth and planetary science. In this session, we welcome papers on various aspects and fields of TC studies. We hope that the session will provide an opportunity to establish new researches among researchers in different fields, and a new direction for future TC researches.
