The water cycle in the Himalaya is poorly understood because of its extreme topography that results in complex interactions between climate, water stored in snow and glaciers and the hydrological processes. Hydrological extremes in the greater Himalayas regularly cause great damage, while high mountain Asia also supplies water to over 25% of the global population. So, the stakes are high and an accurate understanding of the Himalayan water cycle is imperative. The hydrology of the greater Himalayas is only marginally resolved due to the intricacy of monsoon dynamics, the poorly quantified dependence on the cryosphere and the physical constraints of doing research in high-altitude and generally inaccessible terrain. However, in recent years significant scientific advances have been made in field monitoring, modelling and remote sensing and the latest progress and outstanding challenges will be presented for three related fields. First focus will be on recent learnings about high altitude climate dynamics and the interaction between the atmosphere and the extreme mountain topography. Secondly, recent advances in how climate controls key glacio-hydrological processes in high-altitude catchments will be discussed with a particular focus on debris covered glaciers. Thirdly, new developments in glacio-hydrological modelling and approaches to climate change impact assessments will be reviewed. Finally, the outstanding scientific challenges will be synthesized that need to be addressed to fully close the high mountain water cycle and to be able to reduce the uncertainty in future projections of water availability and the occurrence of extreme events in high mountain Asia.
