Proposing a systematic framework of dynamic periglacial geomorphology

We compiled data from long-term field monitoring of various periglacial processes and their controls, as well as data on the distribution, morphology and structure of resulting periglacial landforms. These data were used to analyze factors controlling the periglacial processes and landforms, to evaluate their climatic significances, and finally to propose a systematic framework of dynamic periglacial geomorphology. The data analyses revealed the thresholds for the generation of rockfall, solifluction and rill erosion, the dynamics of rock creep and rock glaciers, and the inter-annual variation and triggers of ice-wedge cracking. Full-scale laboratory simulations of frost sorting processes successfully produced incipient forms of sorted patterned ground.
