Outline of Final Research Achievements

1. The website "Japan-Asia Climate Data Program" was set up for sharing the 19th century meteorological data in Southeast/East Asian countries and reconstructed temperature data from weather discriptions of Japanese historical documents.
2. Meteorological records in the Philippines since 1865 were recovered. Regarding the number of rainy days in summer, there were more than 20 days for 1900s - 1960s. However, there were less rainy days for 1865-1875 and after 2000.
3. Winter and summer temperatures since the 19th century were reconstructed from weather discriptions of historical documents in Yamagata Pref.It revealed that winters before the mid 19th century were rather colder than present, and summers during 1850-1880 were very hot.
