Comparison of thermodynamics solvers in the polythermal ice sheet model SICOPOLIS
Ralf Greve, Heinz Blatter
In order to model the thermal structure of polythermal ice sheets accurately, energy-conserving schemes and correct tracking of the cold-temperate transition surface (CTS) are nece…
Comparison and verification of enthalpy schemes for polythermal glaciers and ice sheets with a one-dimensional model
Heinz Blatter, Ralf Greve
The enthalpy method for the thermodynamics of polythermal glaciers and ice sheets is tested and verified by a one-dimensional problem (parallel-sided slab). The enthalpy method alo…
Decay of the Greenland Ice Sheet due to surface-meltwater-induced acceleration of basal sliding
Ralf Greve, Shin Sugiyama
Simulations of the Greenland Ice Sheet are carried out with a high-resolution version of the ice-sheet model SICOPOLIS for several global-warming scenarios for the period 1990-2350…
Fluid dynamics of planetary ices
Ralf Greve
The role of water ice in the solar system is reviewed from a fluid-dynamical point of view. On Earth and Mars, water ice forms ice sheets, ice caps and glaciers at the surface, whi…
A continuum-mechanical model for the flow of anisotropic polar ice
Ralf Greve, Luca Placidi, Hakime Seddik
In order to study the mechanical behaviour of polar ice masses, the method of continuum mechanics is used. The newly developed CAFFE model (Continuum-mechanical, Anisotropic Flow m…
MAIC-2, a latitudinal model for the Martian surface temperature, atmospheric water transport and surface glaciation
Ralf Greve, Bjoern Grieger, Oliver J. Stenzel
The Mars Atmosphere-Ice Coupler MAIC-2 is a simple, latitudinal model, which consists of a set of parameterisations for the surface temperature, the atmospheric water transport and…
Continuum-mechanical, Anisotropic Flow model for polar ice masses, based on an anisotropic Flow Enhancement factor
Luca Placidi, Ralf Greve, Hakime Seddik +1
A complete theoretical presentation of the Continuum-mechanical, Anisotropic Flow model, based on an anisotropic Flow Enhancement factor (CAFFE model) is given. The CAFFE model is…
Numerical simulation of the evolution of glacial valley cross sections
Hakime Seddik, Ralf Greve, Shin Sugiyama +1
A numerical model was developed for simulating the formation of U-shaped glacial valleys by coupling a two-dimensional ice flow model with an erosion model for a transverse cross s…
