Highlights:

• The study shows the response of stable isotopes in precipitation to ENSO events and the spatial distribution of water sources from a particular region in order to understand how water vapor from a particular region might influence the isotopic variability due to ENSO using a simulated isotopic model (Figure 1).
• In addition, we propose several plausible factors that control the isotopic variation during ENSO. In General, the depletion and enrichment of stable isotopes correspond to the appearance of zones of convergence and divergence over the Maritime Continent during La Niña and El Niño, respectively.
• An asymmetric ENSO feature is found in this study, evidenced by the similar contributions of water source quantity from the northern Maritime Continent and the Pacific Ocean during both ENSO phases.
