Short summary
Short summary
Glacierised valleys create unique local-scale winds. Most glaciers in the world are ungauged, making it hard to estimate the melt contribution of heat exchanged by these winds. We developed a model that predicts wind speed on any glacier without requiring any in-situ data, enabling wind predictions on ungauged glaciers. Our predictions are about three times more accurate than a standard climate product, helping improve estimates of glacier melt and runoff in a warming climate.

A comprehensive rock glacier inventory (n = 5492) has been generated through manual delineation in a GIS environment for the western Himalayan region. The inventory has characterized each rock glacier with 22 attributes following the standard protocols. This inventory shall serve as a baseline for the future research related to rock glacier dynamics, their hydrological contribution and response to climate change.

Short summary
Short summary
A study of two glacierised Himalayan catchments reveals that the summer runoff from the glacierised parts of the catchments responds strongly to temperature forcing and is stable to precipitation forcing, while that of the non-glacierised parts has an exactly opposite behaviour. The pattern of changes in mean runoff and its variability under a warming climate is determined by the response of glaciers to temperature forcing, and that of off-glacier areas to precipitation perturbations.

Short summary
A model study of two Himalayan catchments reveals that the summer runoff from the glacierized parts of the catchments responds strongly to temperature forcing and is insensitive to precipitation forcing. The runoff from the non-glacierized parts has the exact opposite behaviour. The interannual variability and decadal changes of runoff under a warming climate is determined by the response of glaciers to temperature forcing and that of off-glacier areas to precipitation perturbations.
