“…Surge-type glaciers throughout HMA have received significant attention in the past decades, with many regional inventories being generated, especially in the Karakoram (Hewitt, 1969;Kotlyakov et al, 1997;Barrand and Murray, 2006;Quincey et al, 2011;Copland et al, 2011;Bhambri et al, 2017), Pamirs (Osipova et al, 1998;Kotlyakov et al, 2008;Shangguan et al, 2016;Lv et al, 2019;Goerlich et al, 2020) and Tien Shan (Osmonov et al, 2013;Mukherjee et al, 2017;Zhou et al, 2021). More recently, glacier surges have been documented in understudied regions of HMA such as the Tibetan Plateau (King et al, 2021;Xu et al, 2021;Zhu et al, 2021) and Western Kunlun Shan Furuya, 2013, 2015;Chudley and Willis, 2019;Muhammad and Tian, 2020). Many of these studies have focused on the modern satellite era and highlighted the non-uniform distribution of surge-type glaciers in HMA, giving a more accurate representation of the prevalence of surge-type glaciers compared to ground-based efforts (Dolgoushin and Osipova, 1975;Kotlyakov et al, 2008;Imran and Ahmad, 2021).…”

Abstract. Knowledge about the occurrence and characteristics of surge-type glaciers is crucial due to the impact of surging on glacier melt and glacier-related hazards. One of the super-clusters of surge-type glaciers is High Mountain Asia (HMA). However, no consistent region-wide inventory of surge-type glaciers in HMA exists. We present a regionally resolved inventory of surge-type glaciers based on their behaviour across High Mountain Asia between 2000 and 2018. We identify surge-type behaviour from surface velocity, elevation and feature change patterns using a multi-factor remote sensing approach that combines yearly ITS_LIVE velocity data, DEM differences and very-high-resolution imagery (Bing Maps, Google Earth). Out of the ≈95 000 glaciers in HMA, we identified 666 that show diagnostic surge-type glacier behaviour between 2000 and 2018, which are mainly found in the Karakoram (223) and the Pamir regions (223). The total area covered by the 666 surge-type glaciers represents 19.5 % of the glacierized area in Randolph Glacier Inventory (RGI) V6.0 polygons in HMA. Only 68 glaciers were already identified as “surge type” in the RGI V6.0. We further validate 107 glaciers previously labelled as “probably surge type” and newly identify 491 glaciers, not previously reported in other inventories covering HMA. We finally discuss the possibility of self-organized criticality in glacier surges. Across all regions of HMA, the surge-affected area within glacier complexes displays a significant power law dependency with glacier length.

“…Surging glaciers occur in most parts of the globe, mainly in the Yukon region of Canada, Alaska in the United States [65], Svalbard and East Greenland in Norway [66], and in HMA, in Karakorum [67][68][69][70][71], western Kunlun [63,72,73], and the Pamirs [52,53,74]. Small portions of surge glaciers are also present in HMA, such as Tian Shan [54,55], Tanggula Shan [56,75,76], Hindu Kush [32], and the interior of the Tibetan Plateau [12,56].…”

Influenced by global warming, glaciers in High Mountains Asia (HMA) generally show a trend of retreat and thinning, but in Karakoram, Pamir, and West Kunlun there is a trend of glacier stabilization or even a weak advance. In this study, using a bibliometric analysis, we systematically sorted the area, mass balance, and elevation changes of the glaciers in Karakoram and summarized the glacier surges in HMA. The study shows that, since the 1970s, the glaciers in the Karakoram region have experienced a weak positive mass balance, with weakly reducing area and the increasing surface elevation. The north slope of Chogori Peak and the Keltsing River Basin presented a glacier retreat rate with a fast to slow trend. The anomaly is mainly due to low summer temperatures and heavy precipitation in winter and spring in the Karakoram region. There are a large number of surging glaciers in the Karakoram Mountains, the Pamir Plateau, and the West Kunlun region in the western part of HMA, especially in the Karakoram Mountains and the Pamir Plateau, which account for more than 70% of the number of surging glaciers in the entire HMA. The glaciers in the Karakoram and Kunlun Mountains are mainly affected by the synergistic influence of various factors, such as hydrothermal conditions, atmospheric circulation, and topography. However, the glaciers in the Pamir region are mainly influenced by the thermal mechanism of the glacier surge. The glaciers in and around Karakoram are critical to the hydrological response to climate change, and glacial meltwater is an important freshwater resource in arid and semi-arid regions of South and Central Asia, as well as in western China. Therefore, changes in the Karakoram anomaly will remain a hot research topic in the future.
