Many studies show that affected by climate change，the soil active layer of the Yellow River source region gradually decreased. Soil temperature and moisture are important physical elements in land surface process and earth system. They have influence on the atmospheric circulation and precipitation through affecting surface energy and mass exchanges. In this paper, two control experiments were conducted for two typical warm/cold climate seasons using the Weather Research and Forecasting model (WRF). Meanwhile, two sensitive simulations were designed to discuss the impact different initial soil conditions on the regional water cycle. The precipitation recycling ratio is considered as an index to explore the impact of land surface process impact on water cycle. We further explore the possible physical mechanism of the impact from the circulation. The following results are obtained. Large-scale circulation has large control on the land effect on the water cycle. The precipitation recycling ratio is about 5% larger in a weaker circulation than in a stronger one. Initial soil conditions have a certain extent impact on the water cycle elements. Warmer/cooler initial soil temperatures make water vapor flux, and post-precipitation increase/decrease. Soil has different memory under different atmospheric circulation. It is longer in a weaker circulation than stronger one. Soil initial condition perturbations can sustain from one month to two months.
