New approaching addressing challenges in the coupling of atmosphere-land surface-hydrology processes: overview and opportunities

摘要：

To address flooding, drought, water resource shortage and water pollution problems, research on the coupling mechanism of atmosphere-land surfacehydrology processes are proposed as an urgent scientific issue, especially the impacts of climate changes and human activity on water cycles. Present studies of the topic were reviewed in this article from three aspects; distributed hydrological modeling, meso-scale atmosphere-land surface coupling and flood forecasting. Existing shortages and problems of present coupling mechanisms were presented; the atmosphere-land surface-hydrology coupling study should take into account multi-scale effect, human activities and climate change. Further studies were needed to conduct simultaneous field observation of hydrologic processes, and develop new generation of distributed hydrology model and atmosphere-land surface-hydrology coupling model for addressing the nonlinear issue, heterogeneity, scale effects and uncertainty in the distributed hydrologic modeling.
