THE ENDOTHERMIC MODEL OF PERCOLATION ZONE OF A GLACIER AND FINDING THE ANALYSIS SOLUTION IN MOVING COORDINATE

Ⅰ. INTRODUCTIONIn the research of glaciology a glacier is divided into dry-snow, percolation, superimposedice and ablation zones according tothe water-thermal regime of the active layer of a glacier. Among them the percolation zone is a zone where exchange, of energy and matter between en-

EXOTHERMIC MODEL OF PERCOLATION ZONE IN A GLACIER

During the ablation period, the melt-water on the surface of percolation zone of a glacier percolates down through the snow layer when it cools and freezes, the latent heat released causes the temperature of metres of the snow layer to rise to 0℃. However, at the end of ablation period melting stops, the snow layer through which melt-water permeated begins to release heat to the air and the temperature on the surface of snow layer decreases. As a result, the melt-water in the snow layer

冰川渗浸带雪层温度与融水渗浸的研究

本文在对实测资料分析的基础上,着重阐述了冰川渗浸带雪层温度的时空变化与融水渗浸规律以及产生这种特殊规律的根本原因,同时建立了冰川渗浸带与大气之间的热量交换以及在对应的交换条件下冰川内部状态;最后得出了描述渗浸带水热输运的数学模型。
