The distribution of hydrological regions A to C is shown in the Supplementary Information and Fig. S1. Region A: ln(Ti/Ca) in MD05-292019 (red) and MD06-306757 (purple), with rainfall consistent with December insolation at 0°N. Region B (green): Borneo stalagmite δ18O record6,7,10, with rainfall consistent with October insolation at 0°N. Region C (blue): Eu/Eu* ratio in MD01-2385 (this study), with rainfall consistent with June insolation at 0°N. Note that the axis direction for all proxy records is such that upwards indicates inferred higher rainfall. The precipitation simulation results from near the three regional proxy records are also compared accordingly. The region of precipitation extraction is a model grid square of dimensions 3.75° × 3.75°, which contains the core locations and potential sediment provenance sources (see Fig. S1 for detailed locations).
