Climate patterns in north central China during the last 1800 yr and its possible driving force

Abstract. We synthesized high-resolution precisely-dated stalagmite records and historical document records from north central China to reconstruct a decadal resolution precipitation record during the last 1800 yr (190–1980 AD). Several notable wet intervals were identified: 190s–290s, 560s–850s, 920s–1000s, 1090s–1130s, 1880s–1910s. The most remarkable dry epoch was inferred in 1330s–1860s, and the driest period was in the first half of the 17th century. Other decade droughts were found in the 300s–310s, 340s, 460s, 880s, 1030s, 1070s, 1210s and 1920s. The precipitation variability shows significant positive correlation with the temperature variability, suggesting a warm-humid or cool-dry pattern in north central China over the past 1800 yr. The abnormal warm-dry climate observed in the late 20th century in this region may suggest that the dominant forcing of climate variability changed from natural to anthropogenic. Solar activity may be the dominant natural force that drove the same-phase variations of the temperature and precipitation in north central China on centennial- to decadal-scale.
