Outline of Final Research Achievements

Weather records were collected and compiled from diaries written in the late 19th to early 20th centuries in the Kyoto area, and their relationships with the meteorological observed data were analyzed. Based on the result of this analysis, a temporally consistent time series of the duration of the Baiu rainy season for about 240 years was reconstructed and the positive trend of the length of the Baiu season during the 20th century was found unprecedentedly significant.
