Simple and partial correlation coefficients between annual or rainy-seasonal precipitation oxygen stable isotope ratio (δ18Op), surface air temperature (T) and precipitation (P) in the Central Asia (CA), South Asia (SA) and East Asia (EA) regions during the past 300 kyr. The rainy seasons in CA, SA and EA are defined as November–March, June–September and May–September, respectively. In partial correlation analysis, T and P are used as the control variable alternatively.
