Modelling and Simulation of Ice/Snow Melting
A moving boundary problem, the so-called Stefan Problem, for the melting of ice is set up, then solved numerically using Matlab. Thereby curves for the position of the boundary between ice and water are produced. From these curves the melting time for a given layer thickness of ice/snow can be found. Furthermore, such curves are also presented when salt is added to the ice. It is seen that the ...
متن کاملWidespread Albedo Decreasing and Induced Melting of Himalayan Snow and Ice in the Early 21st Century
BACKGROUND The widely distributed glaciers in the greater Himalayan region have generally experienced rapid shrinkage since the 1850s. As invaluable sources of water and because of their scarcity, these glaciers are extremely important. Beginning in the twenty-first century, new methods have been applied to measure the mass budget of these glaciers. Investigations have shown that the albedo is ...
متن کاملPitted rock surfaces on Mars: A mechanism of formation by transient melting of snow and ice
[1] Pits in rocks on the surface of Mars have been observed at several locations. Similar pits are observed in rocks in the Mars‐like hyperarid, hypothermal stable upland zone of the Antarctic Dry Valleys; these form by very localized chemical weathering due to transient melting of small amounts of snow on dark dolerite boulders preferentially heated above the melting point of water by sunlight...
متن کاملCloud Detection over Snow and Ice Using MISR Data
Clouds play a major role in Earth’s climate and cloud detection is a crucial step in the processing of satellite observations in support of radiation budget, numerical weather prediction and global climate model studies. To advance the observational capabilities of detecting clouds and retrieving their cloud-top altitudes, NASA launched the Multi-angle Imaging SpectroRadiometer (MISR) in 1999, ...
متن کاملRescuing traditional ( historical ) linguistics from grammaticalization theory
There is a rich history, dating back, according to Heine (2003), at least to observations in the 18th century by Condillac (1746) and Horne Tooke (1857) (first published 1786), if not earlier, associated with the study of the phenomenon of grammaticalization, i.e. how grammatical elements arise out of less (or non-) grammatical elements. 1 Still, only in the past twenty-five or so years has it ...
