GLI MMER(Genie Land Ice Model with Multipy-Enabled Regions)是英国Edinburgh大学开发的3D热动力陆冰模式,由运动方程、连续方程、热力学方程构成其主要物理框架,能与全球气候模式进行耦合,适用于冰川过程机理研究和冰川数值预报.介绍了3D GLI MMER陆冰模式,包括它的动力框架、边界条件、数值积分方法和外部强迫.此外,以青藏高原现代冰川为例进行数值试验,考察模式对冰川的模拟能力.结果表明:3D GLI MMER模式可以较好地模拟青藏高原冰川,所模拟的冰川分布、冰厚、冰温和冰速与实际观测比较接近.
The GLI MMER (Genie Land Ice Model with Multipy-Enabled Regions) is a 3D thermodynamic ice-land model developed by the University of Edinburgh, UK. Its main physical framework consists of equations of motion, continuous equations and thermodynamic equations. It can be coupled with global climate models and is applicable In the research on glacier process mechanism and glacier numerical prediction, the 3D GLI MMER land ice model is introduced, including its dynamic framework, boundary conditions, numerical integration method and external forcing.Furthermore, taking the modern glacier in the Qinghai-Tibet Plateau as an example, The results show that the 3D GLI MMER model can simulate the glacier in the Qinghai-Tibet Plateau well, and the simulated glacier distribution, ice thickness, ice temperature and ice speed are close to the actual observation.
