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 We synthesized high-resolution precisely-dated stalagmite records and historical document records from north central China to reconstruct a decadal resolution precipitation record during the last 1800 years (190–1980 AD). The synthesized precipitation record shows coincident variations and significant positive correlations with the temperature reconstructions on centennial- to multidecadal-scale, suggesting warm-humid/cool-dry was the main climate pattern in north central China over the past 1800 years. Solar activity may be the dominant force that drove the same-phase variations of the temperature and precipitation in north central China.
