The Hydro-climate of the Andes: Current Understanding and Future Challenges
Session ID#: 78709
Session Description:
The Andes cordillera, the longest in the world, runs from northern South America (11°N) to the southern tip of the continent (â¼53°S) encompassing a rich variety of mountain climates and ecosystems -from very rainy conditions to hyper arid- and producing sharply contrasting climate conditions over its eastern and western sides. The Andes cross seven countries and is home to about 90 million inhabitants relying on this natural water tower. The steep topography also sets the stage for diverse hazards.
This session aims to review the current understanding of the Andean hydro-climate and discuss pressing research challenges, instrumentation and monitoring needs, and human capacity building. We welcome submissions from the local to the continental scales, and from diurnal to interdecadal timescales, with special emphasis on emerging new topics including water and energy budgets, high impact events, precipitation hotspots, climate change and deforestation impacts, climate-vegetation interactions and cryosphere studies, among others.
