大学院教育 Dynamics of ice sheets and glaciers (2006)
Ice sheets and glaciers are an active, dynamic part of the Earth’s climate system on time-scales of decades and more. More than 90% of the terrestrial freshwater reserves are stored in these ice masses. Their complete disintegration would lead to a global sea-level rise of approximately 70 meters and would have severe impacts on the atmospheric and oceanic circulation. Against the background of future global climate warming due to ongoing emissions of greenhouse gases, understanding the behaviour of these ice bodies is of great relevance. In this lecture, based on the general framework of continuum-mechanical balance equations, the dynamics and thermodynamics of ice sheets (including attached ice shelves) and glaciers will be treated.
