EXOTHERMIC MODEL OF PERCOLATION ZONE IN A GLACIER
<正> 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 refreezes
