Tropical cyclones (TC) cause severe disasters in many countries by torrential rainfall and destructive winds. Strong TCs caused severe damages in many areas of Japan in this couple years; 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, TCs are expected to intensify in the future. Therefore, it is an urgent problem to obtain deeper understanding of mechanisms on TC intensity, structure, and motion, more accurate mid- to long-term projections of the TC parameters, 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 of TC studies. We hope that the session will provide a new direction for future TC researches.
