In 2019, Typhoon Faxai (T1915) hit the Kanto District and caused a long-term shut-down by high winds. In October, Typhoon Hagibis (T1919) provided a huge amount of water vapor and contributed to the record breaking heavy rainfalls over the Japanese Islands. In 2020, Typhoon Haishen (2020) approached Japan; the typhoon exhibited unique concentric eyewall structures and underwent eyewall replacement cycle over the sea south of the Japanese Islands. Tropical cyclones (TCs) often cause tremendous disasters in the coastal regions by torrential rainfall, gale, storm surge, and high surf. A number of future projection studies have implied that higher-latitude occurrences of intense TCs will increase, because the projected future increase in sea surface temperature is larger at higher latitudes. Understanding such phenomena associated with translation, intensity change, and precipitation of TCs and their accurate forecasts are still challenging issues to be solved in the earth and planetary science.
Advances in innovative observations including meteorological aircrafts and next generation satellites, and supercomputers have led to novel development of numerical weather forecasting and understanding of the phenomena in both the forecast and long-term projection. In this session, we welcome papers on various aspects of TC studies. We hope that the session will provide new direction for future TC research activity.
