Precipitation Variability and Extreme Events in Eastern China during the Past 1500 Years

Abstract: A proxy precipitation index dataset for the period 501- 2000 over eastern China (east of 105°E; 25- 40°N approximately) was statistically derived from three existing datasets, which were reconstructed based on Chinese historical documents and instrument measurements. The index was then used to ana-lyze decadal-to-centennial precipitation variability with a focus on three sub-regions, North China Plain (34- 40°N approximately), Jiang-Huai area (31- 34°N approximately) and Jiang-Nan area (25- 31°N approximately). In addition, major drought/flood events considering severity, persistency, and spatial coverage were also identified. On the centennial time scales, precipita-tion variation in eastern China exhibited four dry epochs (500s- 870s, 1000s- 1230s, 1430s- 1530s and 1920s- 1990s) and three wet epochs (880s-990s, 1240s- 1420s and 1540s- 1910s), with multi-decadal dry/wet fluctuations within each epoch. However, variation showed strong regional differences, for example, opposite trends were found in the Jiang-Nan area and Jiang-Huai area during the 11- 13th centuries and in the North China Plain and Jiang-
