An annually resolved and absolutely dated ring-width chronology spanning 4,500 y has been constructed using subfossil, archaeological, and living-tree juniper samples from the northeastern Tibetan Plateau. The chronology represents changing mean annual precipitation and is most reliable after 1500 B.C. Reconstructed precipitation for this period displays a trend toward more moist conditions: the last 10-, 25-, and 50-y periods all appear to be the wettest in at least three and a half millennia. Notable historical dry periods occurred in the 4th century BCE and in the second half of the 15th century CE. The driest individual year reconstructed (since 1500 B.C.) is 1048 B.C., whereas the wettest is 2010. Precipitation variability in this region appears not to be associated with inferred changes in Asian monsoon intensity during recent millennia. The chronology displays a statistical association with the multidecadal and longer-term variability of reconstructed mean Northern Hemisphere temperatures over the last two millennia. This suggests that any further large-scale warming might be associated with even greater moisture supply in this region. STUDY NOTES: Reconstructed annual precipitation for the Northeastern Tibetan Plateau for the past ~3500 years, based on tree ring data (Juniperus przewalskii Kom.). The reconstructed values represent annual precipitation totals (mm) for the previous July to current June for the NE Tibetan Plateau region, as shown in Fig. 3. of Wang et al. 2014. The confidence interval values given here represent 1 standard deviation of the two components of reconstruction uncertainty (chronology error and precipitation representation uncertainty) and the combined total reconstruction uncertainty. The latter is the square root of the sum of the three error/uncertainty components. For further information, see the Yang et al.
