Glacial morphology and snow-lines of younger Quaternary around the Yari-Hotaka Mountain range, northern Alps, central Japan
In this paper, the authors attempt to elucidate the glacial geomorphology to clarify the ages of glacial stages by correlating with some glacial stages in other areas, to study some problems of snow-line reconstruction, and to reconstruct the change
of the altitude of snow-line using geomorphological and meteorological data. (L'A.).
On the basis of empirical findings and inductive conclusions, the least extent of glaciation during the last ice age can be shown for 2 areas on the southern slopes of the Himalayas in Nepal. For the Rolwaling Himal, the snowline during the last
ice age is calculated at 4000 m asl., i.e., 1500 m below the recent snowline. The last high-glacial snowline in the Kangchenjunga Himal is thought to be at 4350 m asl., the snowline depression here is 1150 m.

is proved; a snow-line (ELA)-depression of 820-1250 m in relation to the present relief has been calculated. Modelling by means of those snow-line depressions and estimations of the precipitation provide ideas about surface heights, ice thicknesses and flow
behaviour of the ice sheet. The hypothesis of a global triggering of the ice age by the uplift of the subtropical Tibet up to above the snow-line motivates the investigations presented here.

Mountain snowline is important as it is an easily observable measure of the phase state of water in the landscape. Changes in seasonal snowline elevation can indicate long-term trends in temperature or other climate variables. Snow-cover influences
local flora and fauna, and knowledge of snowline can inform management of water and associated risks. Between 1945 and 2007 voluntary observers collected a subjective record of snow cover across Great Britain called the Snow Survey of Great Britain (SSGB
). The original paper copy SSGB data is held by the Met Office. This article details the digitisation of the Scottish SSGB data, its spatial and temporal extents, and a brief example comparison of Met Office snow-lying gridded data. The digitised SSGB data

This paper reviews methods of climatic interpretation of glacier fluctuations on time scales of 103 to 104 years. Glacier dynamics are not considered; rather, the problem is approached from the perspective of pertubations in the equilibrium-line

-Tibet Plateau is higher than that at the edge of the plateau. On the Qinghai-Tibet Plateau, the 30°N latitude line appears to be significant in the context of snow disaster.
Based on the hazard harmfulness data collected from historical records and data collected from entities affected by this hazard in 2010, a comprehensive analysis of the 18 indexes of snow disaster on the Qinghai-Tibet Plateau was conducted
, encompassing the hazard harmfulness, the amount of physical exposure the hazard-bearing entities face, the sensitivity to the hazard, and the capacity to respond to the disaster. Overall, the risk of snow disaster in high-altitude areas of the central Qinghai
