While extreme heavy rainfall events occurred in some years, severe drought events occurred in other years. A strong interaction between these scales could be important for the water cycle in the area.
Precipitation changes the fluxes of heat and water vapor from the ground.
The followings are main scientific goals of the research. In addition to the deeper understanding of multi-scale physical processes of energy and water cycle in the Huaihe River Basin and its surrounding area, the following products are expected. It will be used in the regional-scale 4DDA, the simulation of rainfall distribution in the Huaihe River Basin and the physical study of energy and water cycle. The model will be applied to the experimental area of Shiguang River Basin. Data format and utilization system will be adjusted through connection with GAIN Center.
