The δ18O values indicate wetter conditions/more rainfall during the early Holocene from 11 to 7 thousand years before present (kyr BP). A large increase of 2? in δ18O is observed from 7.0 to 6.0 kyr BP, indicating a millennial drying period followed by drought conditions between 6.0 and 5.2 kyr BP. After a long hiatus (5.2–2.7 kyr BP), δ18O data show a millennium-long trend toward dry conditions. An abrupt positive change of 0.8–1.0? in δ18O is noticed between 8.29 and 8.17 kyr BP, reflecting the 8.2-ka event; however, the amplitude of the δ18O shift is much smaller comparing to that of the event of 6.0–5.2 kyr BP. On orbital time-scales, the TK record agrees with insolation-dominated speleothem records in the Asian-Australian monsoon realm. Noticeable inconsistencies among records in the Southeast Asia region (between 8°N and 4°N–8°S) have been documented on multi-centennial scales. Lower δ18O values are likely associated with the mean position of the Intertropical Convergence Zone (ITCZ). A new reconstruction of Holocene ITCZ shifts index within the central Indo-Pacific region, based on stalagmite δ18O records from Klang Cave (8°N) and Liang Luar Cave (8°S), shows that the ITCZ played an important role in hydroclimate variability in the Asian-Australian monsoon regions. The southward shift of the ITCZ in the central Indo-Pacific region, controlled by the interhemispheric extratropical insolation gradient, may strongly correlate with the El Ni?o-Southern Oscillation (ENSO) activities in the Holocene. ? 2020 Elsevier LtdAtmospheric pressure; Atmospheric thermodynamics; Climatology; Incident solar radiation; Drought conditions; Early Holocene; Insolation gradients; Intertropical convergence zone; Positive changes; Southeast Asia; Southern oscillation; Southern Thailand; Caves; El Nino-Southern Oscillation; Holocene; hydrometeorology; insolation; intertropical convergence zone; monsoon; rainfall; Indian Ocean; Malay Peninsula; Pacific Ocean; Thailand[SDGs]SDG13[SDGs]SDG15journal article10.1016/j.quascirev.2020.1067792-s2.0-85099214634
