Five years (FY2005-FY2009: April 2005-March 2010) program of "HARIMAU (Principal Investigator [PI]: Manabu D. Yamanaka)" is funded by the Ministry of Education, Culture, Sports, Science and Technology of Japan (MEXT) as a part of "Japan Earth Observation System [EOS] Promotion Program (JEPP)". The HARIMAU starts practically from FY2006 (April 2006) in addition to the successive IORGC/JAMSTEC scientific activities which have been collaborated with BPPT (,BMG and LAPAN) in Indonesia.
Main objectives are as follows:
Further physical understandings of intraseasonal variation (ISV; period of 60-90 days, see Fig. 1) in terms of convective and rainfall activities over the maritime continent which might have great effect on the global climate changes, such El-Nino and Southern Oscillation (ENSO) and Indian Ocean Dipole mode (IOD), through the tropical ocean-atmosphere interaction.
Contribution to prevention from natural disasters such as flush flood, landslip, drought, and air pollution, caused by extraordinary weather in relation to the ISVs through monitoring atmosphere continuously and real time data distribution to govornmental institutions.
Providing statistical observation data and chance to study how to deal with them which are useful for such as agricultural meteorology, water responce management, aviation meteorology, air pollution control, and capacity building for younger scientists.
