جایگاه گیاه cochlearia conwayi مورد بحث قرار می گیرد و این گونه به جنس pseudocamelina انتقال داده می شود. ترکیب جدید p. conwayi پیشنهاد می گردد. ویژگی های تعیین کننده گونه های جنس cochlearia که از مرکز، جنوب و جنوب غرب آسیا شرح داده شده اند مورد بحث قرار می گیرند و نتیجه گیری می شود که این جنس در آسیا نمی روید و تنها در شمالی ترین بخش آن حضور دارد.
Due to the scarcity of field observations and geodetic measurements in catchments in the Karakoram Mountains in Western China, obtaining precipitation data for the high mountains involves large uncertainties and difficulties. In this study, we used a functional relationship between the annual glacier accumulation and summer temperature at the equilibrium line altitude (ELA) to derive precipitat...
Owen, L.A. 1989. Neotectonics and deformation in the Karakoram Mountains and Nanga Parbat Himalaya. In: N.-A. Momer and J. Adams (Editors), Paleoseismicity and Neotectonics. Tectonophysics, 163: 227-265. The Karakoram Mountains and the Nanga Parbat Himalaya are one of the most rapidly rising mountain areas in the world with uplift rates in the order of 2 mm/yr. Large-scale regional warping is t...
Abstract Under global warming, many glaciers worldwide are receding. However, recent studies have suggested the extension of Karakoram Anomaly, a region anomalous glacier mass gain, into western Kunlun and eastern Pamir mountains. limit this anomaly in Mountains is unclear. This study, using changes area surface elevation, estimates Kunlun-Pamir-Karakoram at ~85°E. Over past 50 years, west 85°E...
Between 2003 and 2007, North Gasherbrum Glacier on the northeastern slope of the Karakoram mountains in Asia underwent a dramatic acceleration, during which a velocity wave propagated down the glacier. There was a significant transfer of ice from up-glacier downstream, which resulted in a strong surface elevation increase over the lower tongue, but only a moderate advance of the glacier snout. ...
Rock glaciers are abundant in the Lahul and Garhwal Himalayas of northern India and the Karakoram Mountains of northern Pakistan. They exhibit morainic and protalus forms and are restricted altitudinally and climatically to sites above approximately 4000 m asl. and regions where annual precipitation is less than 1000 mm. In these areas, morainic rock glaciers are large, usually )1 km long, )100...
impressive Quaternary lacustrine deposits are present as terrace remnants throughout the Karakoram Mountains, northern Pakistan. They are mainly the result of damming of drainage systems during glacial advances or by catastrophic mass movement deposits. The longevity of most lakes is relatively short, in the order of years to tens of yeaa, but sedimentation rates are extremely high as a consequ...
Temperature data for seven instrumental records in the Karakoram and Hindu Kush Mountains of the Upper Indus Basin (UIB) have been analyzed for seasonal and annual trends over the period 1961–2000 and compared with neighboring mountain regions and the Indian subcontinent. Strong contrasts are found between the behavior of winter and summer temperatures and between maximum and minimum temperatur...
Infrastructure has played an agential role in the securitisation of everyday life Karakoram high mountains north Pakistan. Geopolitics bear heavily on this region where Pakistan shares borders with China, whom it aligned its foreign and security policy, India, remains embroiled a long-standing territorial dispute. Consequently, Karakoram, geopolitical anxieties have reflected inwards onto local...
