| Outline of Final Research Achievements |
To clarify climate changes in the Southeast Asia and its relation to the air-sea interaction in the tropics in centennial scale, this study investigated the onset and withdrawal of the rainy season at Manila for the period 1868-2012 and the seasonal march patterns of rainfall in the Philippines for the period 1951-2012, and showed their long-term variability for the first time. While the interdecadal variability was observed in the onset and withdrawal of the rainy season since the late 19th century, the abnormalities in the seasonal march patterns of rainfall were frequently showed since the 1990s. This is because the recent ENSO (El Nino-Southern Oscillation) greatly influenced the strengths in the subtropical high around the Philippines during March-April and the Asian summer monsoon around the western North Pacific. It is suggested that their changes induced the long-term changes in the seasonal march of rainfall in the Philippines in centennial scale.
