North-Central China 400 Year Precipitation Reconstructions Yi, L.; Yu, H.; Xu, X.; Yao, J.; Su, Q.; Ge, J. Yi, L. Yu, H. Xu, X. Yao, J. Su, Q. Ge, J. Precipitation Reconstruction drought earth science/paleoclimate/climate reconstructions (precipitation,multiple proxies,null,millimeter,Jun-Aug,climate reconstructions,null,null,N,null) earth science/paleoclimate/climate reconstructions (precipitation,multiple proxies,null,millimeter,Apr-Jul,climate reconstructions,null,null,N,null) earth science/paleoclimate/climate reconstructions (age,null,null,year Common Era,null,climate reconstructions,null,null,N,null) earth science/paleoclimate/reconstructions (North-Central China Region B>LATITUDE 39.5>LONGITUDE 112) (North-Central China Region A>LATITUDE 34.5>LONGITUDE 110) Two robust precipitation reconstructions were conducted by combining tree-ring chronologies, dryness/wetness indices from historical documents, and climate data from the global grid. It was found that the recurrent drought history of a region can help us understand the variability of precipitation. Several dry/wet periods during the past four centuries and potential cycles of precipitation variation were determined. Furthermore, the reconstructions are not only consistent well with each other in North-central China, but also in good agreement with variations of precipitation in northeastern Mongolia, the Longxi area in Gangsu Province and the Dulan area of Qinghai Province, and the snow accumulation of the Guliya glacier. These synchronous variations indicate that it is valuable to study various climate records, find common information and determine the driving force of climate change. STUDY NOTES: Multiproxy spring-summer precipitation reconstructions for two regions of north-central China over the last 4 centuries. Reconstructions are based on tree-ring chronologies, dryness/wetness indices from historical documents, and instrumental climate data.
