Exploratory Precipitation in North-Central China 
during the Past Four Centuries.

  <Summary>
    <Abstract>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tree-ring chronologies, dryness/wetness indices from historical 
documents, and climate data from the global grid.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indices from historical documents, and instrumental climate data.
