The rain gauge data were observed routinely by the Department of Meteorology and Hydrology in Myanmar, the Thai Meteorological Department, the Department of Meteorology and Hydrology in Laos, the Department of Meteorology in Cambodia, and the National Hydrometeorological Service of Vietnam. Data were collected by the Climate Research Laboratory of the Department of Earth and Planetary Science at the University of Tokyo under the GAME-Tropics and other related projects conducted in this laboratory. The authors are grateful to these agencies and laboratory for their provision of the data. This study was supported financially by a Grant-in-Aid for the 21st Century COE Program (Kyoto University), a Grant-in-Aid for Scientific Research B-2-15340157 of the Japanese Ministry of Education, Culture, Sports, Science and Technology, and by Core Research for Evolutional Science and Technology, the Japan Science and Technology Agency (Leader: Prof. Masakazu Suzuki). All figures were produced with the use of the GFD-DENNOU library.
