Chinese historical documents contain abundant descriptions of weather conditions that can be used to reconstruct the climate over hundreds and perhaps thousands of years-in this case precipitation between 1736 and 1911.
Long-term, high-resolution climate data are needed to study regional climate variability on decade-to-century time scales, and for evaluating climate model simulations of past climate. Historical documents, in which weather conditions are described qualitatively, and sometimes even quantitatively, provide a unique source for climate reconstruction of the past few centuries (Zhang and Crowley 1989; Bradley et al. 1993; Pfister 1995; Mikami 1999; Pfister et al. 2002; …
