- Changes in precipitation were found more synchronous with the WNPSM than with the ISM. Fluctuation of the WNPSM primarily influenced precipitation variation on the downstream left bank, and 29.3% of the basin was found to exhibit significant positive correlation with the WNPMI. In comparison, fluctuation of the ISM mainly affected the western boundary of the lower Lancang–Mekong River Basin, and the affected area was much less.
- Topographic features amplified the effects of WNPSM fluctuation. During the strong WNPSM years, the anomalous westerlies crossing the Annamite Mountains carried greater quantities of water vapor that result in enhanced orographic precipitation on the windward side, and vice versa.
- River flow below Nong Khai station was found to be positively and significantly correlated with the WNPMI, which was consistent with the area where most of this river flow was generated, and precipitation variation was induced by WNPSM fluctuation. At the Mukdahan, Pakse and Stung Treng stations, the differences in flow between strong and weak monsoon years were 13.0%, 20.7% and 31.6%, respectively, indicating that the WNPMI would be helpful for long-term hydrological predictions.
