| 中文摘要 | One of the most important questions of climate change impact research today is how glaciers are responding to global warming. High Mountain Asia (HMA) glaciers represent the largest mass of ice outside the Polar Regions and provide water resources for millions of people in the headwaters of the major Asian rivers. Nevertheless, their historical changes and future trends are unclear, due to a scarcity of direct observations and fundamental limitations in simulation models. This project will provide a step-change in our understanding of the response of HMA glaciers and runoff to a warming climate by solving some of the remaining unknowns in HMA glaciers and catchment response to climate: i) precipitation amounts at high elevation; ii) spatial variability of precipitation and snow; and iii) debris-covered glaciers. We will incorporate knowledge of snow processes and debris-covered glaciers dynamics obtained from detailed, local-scale process-based modelling and observations into a new model of glacier mass balance and high mountain hydrology. The new model will be informed by novel observations of glacier surface characteristics, glacier changes and hydrology and forced with high resolution climatic input generated by two new international efforts to run high resolution climate models over the entire HMA. The model will then be used to simulate glacier response and unravel the hydrological functioning of selected catchments across the wide variety of climates and glacier characteristics of HMA, bridging the scale gap between single point scale studies and very large simulations that up to now relied on simplistic model assumptions. The project will provide a new physical basis for the distinct patterns of glacier changes in HMA that have been suggested recently but lack explanations, having been inferred from sparse observations or derived from remote sensing studies. This project capitalises on data, established links of collaboration and ongoing modelling from large research efforts and joint ongoing projects by the Swiss and Chinese applicants, who have been collaborating with complementary expertise to study selected processes and glaciers in the region. In this new project, we have assembled a unique team of world-leading international partners that will provide datasets and expertise for a timely and novel synthesis of glacier, snow and river response across HMA climatic gradients and scales. We have made a major effort to go beyond disciplinary approaches and expertises and merge them into a truly integrated synthesis of both datasets and modelling efforts to establish the scientific evidence of glacier and runoff changes beyond single case studies. We are truly pleased by the interest and support by this large network of international partners and the opportunity to combine ongoing research efforts to address a novel programme of synthesis of knowledge in HMA. |
