5 Conclusion
The water vapor content of the air mass has a decisive influence on the evaporation of the reservoir. The humid air mass from the southeast monsoon affects the area when the evaporation is weak, and the dry air mass from the westerly wind affects the area with strong evaporation. Evaporation from the reservoir has obviously affected the precipitation in the area around the reservoir. The impact range is related to the local atmospheric movement mode, Evaporating water vapor affects the precipitation in high altitude areas in the Xiying River Basin. Although the calculations regarding the contribution of reservoir evaporation to local precipitation still has significant uncertainties associated with the use of the stable isotope algorithm, these uncertainties will be further reduced with an increase of observation data and improvement of the algorithm itself.
