Temporal variability of alpine solifluction : a modelling approach
Abstract. Holocene periods of enhanced solifluction offer new paleoclimatic information. Long-term observations of present solifluction variability and process studies on movement mechanisms, as well as model simulations of the soil heat and water regimes, show the dependence of solifluction on ground freezing. The annual variability of both processes is strongly controlled by weather and resulting snow conditions immediately before and at the beginning of the winter frost period. Simulated long-term variations during different paleoclimatic scenarios are regulated by both mean preeipitation and temperature changes. Quantitative reconstruetion of Holocene preeipitation during maximum altitudinal depression of solifluction is shown.

Temporal variability of alpine solifluction : a modelling approach
Holocene periods of enhanced solifluction offer new
paleoclimatic information. Long-term observations of
present solifluction variability and process studies on
movement mechanisms, as well as model simulations
of the soil heat and water regimes, show the dependence of solifluction on ground freezing. The annual
variability of both processes is strongly controlled by
weather and resulting snow conditions immediately
before and at the beginning of the winter frost period.
Simulated long-term variations during different paleoclimatic scenarios are regulated by both mean preeipitation and temperature changes. Quantitative reconstruetion
of Holocene preeipitation during maximum
altitudinal depression of solifluction is shown
