Intensified occurrences of snow droughts are related to the snow cover dynamics in the Hindu Kush Himalayas.

ABSTRACT: Identification of potential snow drought (SD) hotspots is critical, especially considering seasonal snow imbalances in the recent years, with snow being one of the significant water resource in the Hindu Kush Himalayas (HKH). The critical linkage between the spatio-temporal anomalies of snow cover days (SCD) and SD remains under-observed in the HKH region. To investigate this linkage, we identified the SD at basin (11 basins) using the snow water equivalent index (SWEI) based on the High Mountain Asia Snow Reanalysis (HMASR) data from 1999 to 2016 water cycle. The declined snow cover days (DSCD) and snow cover persistence anomalies (SCPA) at sub-km spatial resolution from 2002 to 2018 were estimated from the improved MOYDGL06 snow cover data, respectively. Our basin scale findings indicate
