| 英文摘要 | Human influence on large-scale changes in the atmosphere, oceans, and the cryosphere has increased in recent decades. However, little is known about the physical processes that transfer the human forcing from large to local climate scales, and thus the effects of future climate change are not fully understood. The scale-dependent transfer problem also applies to glacier loss on high mountains, which is a vital indicator of climate change in the understudied air layers of the mid-troposphere. --- This project aims to enhance our knowledge of climate change at high altitude on the process-level. Its major goal is to reveal the mechanisms of human influence on glacier loss across the multitude of space-time scales: from the large-scale climate dynamics, through the regional atmospheric flow over mountains, down to the local air layers above the glaciers. Global climate simulations with and without human forcing, a novel downscaling model, and exceptional in-situ measurements on glaciers allow us to solve the multi-scale problem in a physically-based way. This will (a) reveal and quantify the dynamical processes that sustain human influence on present glacier mass loss, and (b) identify the "Achilles heels" of the multi-scale system, i.e. the locations and features of the most sensitive feedbacks. --- There will be significant impact beyond cryospheric research. For the understanding of the global climate system, our results will extend the physical basis of surface-troposphere interactions, and thus of glacier contribution to future sea-level rise. At regional and local scales, the results will benefit climate impact studies for constraining projections of water resources and natural hazards, which are affected by glacier loss. Results will open new directions for local climate impact studies in general, and for paleoclimatology which uses historic glaciations as indicators of past climatic processes. |
