“…A certain correspondence was found for Tien Shan as both air temperature and precipitation in 1950s were at their low compared to previous and following decade, in the 1990s the air temperature raised rather slowly from its low at the end of previous decade (Černý et al 2007). Liu et al (2014) studied correlation between GLOF events and air temperature in Tibet and confirm that 1960s, 1980s and 2000s were very active periods for GLOFs due to higher temperatures during ablation season but also during accumulation.…”

“…It means the diference between the two lake types would not probably be that large if only the latest data were included. Liu et al (2014) also note that the timing of outburst is influenced by lake's altitude -the higher altitude, the later burst within a season. However, in our case the lake's altitude is not of such importance to influence the outburst timing as the lakes are situated in similar altitude.…”

Glacial lake outburst flood (or shortly GLOF) has become a well-known phenomenon, one of natural hazards occurring in glaciated high mountain areas of the world. The aim of this study was to investigate temporal distribution of these events in Asia and to assess causes of lake outbursts. Therefore, a search of scientific literature and reports was carried out resulting in 219 flood cases found. In order to detect possible differences in temporal distribution a group of ice-dammed lakes was detached and compared with the rest. Concerning spatial distribution of GLOFs, it is influenced by availability of scientific literature which is determined by research teams' region interest. Temporal analysis revealed a certain pattern in ice-dammed lake outburst distribution and notable difference between the two lake groups in terms of outburst occurrence within a year. The moraine-dammed lake outbursts were recorded earlier in an ablation season (compared to ice-dammed lakes) which could be attributed to different mechanism of dam failure. Majority of lake outburst causes were included in the category of dynamic causes (e.g. ice avalanche), long-term causes (e.g. dead-ice melting) were less represented. Results of the study imply there can be notable variations of temporal distribution and causes of GLOFs among individual mountain regions even within one continent. Therefore, varying behavior of potentially dangerous lakes should be taken into consideration when, for instance, proposing mitigation measures.

“…Temperature rise, especially the increasing warming with altitude, is remarkable especially in the Tibetan inhabited areas, which is geologically young and fragile and is vulnerable even to minor changes in the climatic system. The shrinkage of glaciers and the increase in size of glacial lakes include changes in the severityand frequency of Glacial Lake Outburst Floods, as glaciers respond to climate change [4]. Air temperature is the most important climate factor for Glacial Lake Outburst Floods, as it plays a prominent role as it is related to radiation balance, turbulent heat exchange, and solid/liquid precipitation ratio [5].…”

Abstract. Tibetan inhabited areas in Sichuan Province are part of Qinghai-Tibet region which is a unique geographic zone due to its high altitude, sparse human population and prevalent pastoral system. In the past decades, the climate in the region is becoming warmer, and this has resulted in the retreating of most glaciers, the uplifting of the snow lines, permafrost degradation, meteorological disasters and related mountain disasters are becoming more severe and frequent. Climate change may directly and indirectly affect economic outcomes in the short to longer term; it also can lead to household impacts, as well as regional impacts.

“…All GLOFs in Tibet took place during the melting season between May and September, which suggests a potential relationship between outbursts and temperature fluctuations (Liu et al, 2011(Liu et al, , 2014. Guangxieco Lake is located in a region affected by the Indian summer monsoon, which is the main transfer belt of water vapor that results in most of the precipitation in the Tibetan Plateau.…”

Abstract. The 1988 glacial lake outburst flood (GLOF) in Guangxieco Lake is studied based on geomorphological evidence, interviews with local residents, field surveys in 1990 and 2007, and satellite images from different years. The findings are as follows. (1) The outburst event was caused by two major factors, namely, intense pre-precipitation and persistent high temperatures before the outburst and the low selfstability of the terminal moraine dam as a result of perennial piping. (2) The GLOF, with the peak discharge rate of 1270 m 3 s −1 , evolved along Midui Valley in the following order: sediment-laden flow, viscous debris flow, non-viscous debris flow, and sediment-laden flood, which was eventually blocked by Palongzangbu River. (3) A comparison between the conditions during the outburst in 1988 and the present conditions suggests a small possibility of a future outburst unless drastic changes occur in landscape and climate. Reconstructing the outburst conditions and the GLOF processes is helpful in assessing a potential outburst in glacier lakes in Tibet.
