High Mountain Asia

High Mountain Asia (HMA) is a geographic region that includes the Tibetan Plateau and surrounding mountain ranges, i.e., the Himalayas, the Karakoram, and the Tian Shan. Climate-related natural hazards, e.g. landslides (see CaTeNA) and Glacier Lake Outburst Floods (GLOFs), pose a threat to human lives in HMA. Here, climate data with high spatial and temporal resolution are crucial for a better understanding of the climatic triggering mechanisms of local hazards, as well as for deepening our knowledge of the coupling of climate and hydrological cycles (see WET). However, meteorological in-situ observations are uneven and sparsely distributed due to the harsh environment and complex terrain in HMA. Therefore, our knowledge of the climate in this region, especially at high mountain elevations, is still limited. In our research within HMA, we use regional climate models (RCMs) for dynamic downscaling (see High Asia Refined Analysis - HAR) to address the above aspects in different research areas (hydrology, cryosphere, natural hazards).

Halji

The Halji River (Halji Khola, Nepal) drains the source area of GLOFs (Glacial Lake Outburst Flood). A GLOF is a sudden release of water from a glacial lake that forms episodically during snowmelt. GLOFs can cause a large number of casualties and enormous economic damage by flooding downstream areas.
