Fig. A1 Annual layer dating of Zuoqiupu ice core based on seasonal variations of δ18O and rBC. Note that the logarithmic transformation of rBC instead of raw data is used for
visual clarity. Dotted lines and solid lines represent the individual values and the 3-point running means, respectively. The dashed lines indicate the annual layer boundaries
Fig. A2 Variations of annual, monsoon and non-monsoon δ18O records of Zuoqiupu ice core and the
respective linear regressions
Fig. A3 Monthly averages of precipitation amount (P) and temperature (T) at the meteorological stations
of Bomi and Zayu for the period 1961-2012 and 1969-2012, respectively
Fig. A4 Profile of the raw deuterium excess (d) data in the Zuoqiupu ice core
Fig. A5 Monthly mean moisture flux (unit: ×105 g m-1 s-1) in the monsoon season during 1948-2011.
Colored areas and vectors both represent vertically integrated moisture flux. The meanings for the
black line and black dot are the same as those in Fig. 3
Table A1 Pearson correlation analyses of ice core δ18O record with temperature (T) and precipitation
amount (P) at the meteorological stations of Bomi (1961-2011 AD) and Zayu (1969-2011 AD). The
subscript of ‘annual’ here indicates the months from previous August to current July, and ‘10-5’ from
previous October to current May
