General Description of the Research Project

Diagnosis of the heart of global atmospheric circulation - seas and rains of Indonesian "maritime continent"
The Indonesian Archipelago controls warm water flowing from the Pacific Ocean towards the Indian Ocean, generating the most active clouds on the earth, which act as the "heart" pumping global atmospheric circulation. Enhancing capacity to make a "diagnosis" of this heart - the seas and rains of Indonesia - makes it possible to improve the accuracy of climate predictions for the whole world. For Indonesia, the improvements of observation and prediction also contribute to mitigating flooding and drought damage and to policymaking in order to achieve climate-adapted social infrastructure and industrial development.

Optimizing land- and sea-based observations to address global climate change, protecting both Japanese and Indonesian people
This project has created an observation network for climate on both land and sea, including radar monitoring of rainclouds and development of buoys for measuring marine climate and seawater temperature, as well as transferring technology to Indonesia. Optimizing the observation network over the Indonesian maritime continent, which holds the key to understanding and predicting fluctuations in global climate, is contributing to the safety of the Indonesian people and of around a quarter of a million Japanese tourists and businessmen in Indonesia, by for instance, revealing the meteorological causes of the January 2013 Jakarta flood, and is boosting Indonesia's credentials as a leading country in the area of climate variability study.
