Use and need for knowledge on ice drift

Part of the Springer Praxis Books book series (PRAXIS)


The ice drift problem contains interesting basic research questions. It is a two-dimensional problem in the branch of mechanics called geophysical fluid dynamics. The medium is a compressible fluid, whose dynamic characteristics are its largely variable strength (low to very high), low inertia, and the irreversibility of mechanical deformation processes. In ice-only dynamics, adjustment of the ice mass to external forcing takes place, ruled by the strength of ice and the forcing characteristics. As ice is relatively thin, the direct Coriolis effect on it is rather weak, in contrast to the atmosphere and ocean, and, therefore, Coriolis acceleration gives second-order modifications.
