he IGCR (JAMSTEC/NASDA) in collaboration with the IPRC (Univ. Hawaii/FRSGC) held an ad hoc symposium on the "Ocean-Atmosphere Coupled Dynamics in the Indian Ocean" in the Tokyo Prince Hotel,Tokyo on December 17-18, 2001.
The symposium was convened by Drs. T. Yamagata and J. P. McCreary Jr., and co-sponsored by Ministry of Education, Culture, Sports, Science and Technology (MEXT), Meteorological Society of Japan (MSJ), Oceanographic Society of Japan (OSJ) and National Oceanic and Atmospheric Administration (NOAA).
The symposium was first of its kind to have an international gathering of leading scientists to discuss the coupled dynamics in the Indian Ocean.
The symposium was timely at the dawn of active research in the Indian Ocean. About 50 distinguished delegates from Japan, Australia, China, France, India, Italy, South Africa, UK and USA presented their new interesting results on the Indian Ocean processes. The most important outcome of this symposium was the identification of the Indian Ocean Dipole (IOD) influences on the global climate variability, which was not realized before as the El Nino Southern Oscillation (ENSO) and the IOD have complementary effect on some region and mutually opposite influence on others.
Some of the intensive presentations highlighted new directions related to the IOD in paleoclimate, marine ecosystem and atmospheric chemistry.
Advanced analysis in the paleoclimate data, like the fossil coral record, reveals the independent IOD in a record of 6000 years. Understandably, the meeting drew a huge audience of about 300 participants.
The symposium was opened to public with a welcome address by Mr. T. Hirano, President of JAM-STEC, followed by opening addresses delivered by Mr. Y. Otsuka, Director, Ocean and Earth Division, MEXT, Dr. S. Thurston, Associate Program Director, Austral-Asia Region, OGP, NOAA and Dr. T. Matsuno, Director General, FRSGC.
The symposium had six sessions; Coupled Dynamics (Chairpersons:
Drs. Godfrey and Yamagata), IOD Influence on Climate in Other Regions, (Chairperson: Dr. McCreary), Interactions among Monsoon, ENSO and IOD (Chairpersons: Drs. Goswami and Navarra), IOD in Other Disciplines (Chairpersons: Drs. Xie and Wajsowicz ), Ocean Variability (2) (Chairpersons: Drs. Lukas, Shetye, Delecluse and Masumoto), Atmospheric Variability (Chairperson: Dr. Nakamura).
The symposium ended with a note to encourage the coupled dynamics studies in the Indian Ocean and to hold such meetings regularly. Dr. Y. Furuhama, Exective Director, NASDA delivered the concluding remarks.
