From: Solar forcing of the Indian summer monsoon variability during the Ållerød period
Southwest monsoon proxy record from the Arabian Sea ODP Hole 723A combined with cave records from India, China and Oman and GISP2 record from Greenland.
Time series of (a) G. bulloides percentage in Hole 723A off Oman Margin, Arabian Sea, the inset figure shows expanded 13.6–13.1 cal kyr BP interval; the calibrated AMS 14C dated intervals are shown by inverted solid triangles, (b) 65° N July insolation26 (NHSI) and IntCal09 Δ14Catm values27, δ18O values of (c) Timta cave9, (d) Qunf cave11, (e) Hulu cave7 and (f) Dongge cave8 and (g) GISP2 record from Greenland6. The vertical grey bar indicates an interval of weak Indian summer monsoon winds aligned with Intra-Ållerød Cold Periods (IACPs) A1 and A2 when solar insolation was less26.
