Construction of an Efficient CSM Sea Ice Model with an Accurate Plastic Solution

拟议的探索性研究将把一个新的海冰动力学数值模式纳入NCAR CSM。新模型采用交替方向隐式(ADI)技术直接求解海冰动量方程，无需迭代，计算效率高。该模型可能非常适合于并行计算。此外，该模型逼近真塑性解，这对于准确预测冰的运动、变形和应力具有重要意义。这项工作很重要，因为在CSM中成功实施ADI模型可能会增强科学界模拟和预测地球气候系统的能力。

The proposed exploratory research will incorporate a new numerical model for sea ice dynamics into the NCAR CSM. The new model is computationally efficient because it uses the alternating directions implicit (ADI) technique to directly solve the sea ice momentum equations without iterations. The model may be well suited for parallel computing. In addition, the model approaches true plastic solution, which is important for accurate prediction of ice motion, deformation and stress. The work is important because success in implementing the ADI model in the CSM is likely to enhance the science community's ability to simulate and predict the earth's climate system.
