C41F:
Understanding the High-Mountain Water Cycle and Cryosphere in the Anthropocene I

Submit an Abstract to this Session



Session ID#: 34255

Session Description:
High-mountain catchments play an important water supplying role and are sensitive to climate change. Yet the monitoring and modelling of such regions remains a challenge, due to poor accessibility, limited data availability and the lack of numerical models that address key cryospheric and hydrological processes in sufficient physical detail. This session brings together studies that focus on integrating observations, remote sensing and numerical models with the aim to understand present and future glacio-, hydro- and meteorological processes in mountainous regions. It focuses on advances in understanding high-altitude meteorology, feedbacks between the cryosphere and atmosphere, glacier and snow dynamics, climate change impacts and the associated hydrological response. The session welcomes in particular studies that: i) link results from atmospheric modelling to the high-altitude water cycle, (ii) advance the process understanding of glaciers, snow and the hydrological cycle, (iv) quantify hydro-meteorological extremes, and (v) assess impacts of climate change using process-based modelling.
