Challenges of Ice Flow Modelings: from Alpine Glaciers on Tibet Plateau to Antarctic Ice Sheet

Glaciers and ice sheets are important components in the global climate system. They are also important fresh water resources that can impact both the river runoffs in the arid regions, for example, Western China, and the global mean sea levels under a continuously warming climate. Reliable ice flow models are thus highly required for a better understanding of the changes of our earth system. With a full Stokes model (FELIX-S) that we develop, we can study the mechanisms of ice flow, for example, the marine ice sheet instabilities and grounding line dynamics. As a further input for ice sheet modeling community, two different full Stokes ice sheet models, FELIX-S and Elmer/Ice, are compared in details on numerical experiments for Marine Ice Sheet Model Intercomparison Project for planview models (MISMIP3D). For the diagnostic experiment P75D, two models present well matched numerical results, indicating inherent consistencies of two Stokes ice sheet systems.

Dr. Tong Zhang received his BS in Material Physics from Northwestern Polytechnical University in 2007,and his PhD  in Physical Geography from University of Chinese Academy of Sciences in 2013. He worked from 2013 to 2015 as a Postdoctoral Associate in the Interdisciplinary Mathematics Institute of University of South Carolina, USA. He is currently an Assistant Professor in Climate system institute, Chinese Academy of Meteorological  Sciences. His research mainly focuses on ice flow modelings for both alpine glaciers and polar ice sheets using parallel 2D and 3D numerical model approaches.
