| Abstract: | The Himalayas has drawn a wide attention in the context of the changing climate.The expansion of glacial lakes shows the variation of climate changes and is of importance to understand the risks of glacial lake outburst flood.On the basis of large scale topographical maps,DEMs,ASTER,images,glacial lake area variation against elevation and the changes of distance between glacial lake and its parent glacier were analyzed and the climatic implications were discussed in the Chinese Himalaya.The results show tha... |
| Keywords: | Himalaya expansion of glacial lake area variation against altitude implication for climate changes |
