Sticky spots and a catastrophe possibility in West Antarctica. (Russian, English) Zbl 1249.86053
Dokl. Akad. Nauk, Ross. Akad. Nauk 437, No. 4, 543-547 (2011); translation in Dokl. Earth Sci. 437, Part 2, 486-489 (2011).
The author develops a model of glacier motion without sticky spots at the glacier’s bed (a model of ideal gliding along the bed). Energy balance equation takes into account a dissipation process due to pseudo-turbulence inside the lateral parts of the glacier/ The pseudo-turbulence in the boundary layers provides deceleration of the ice flow, and possibility of catastrophic avalanche is discussed.
