Highlights: • Snow and glacier melt is one of the major source of water in Himalaya and it influences the water security in north-India. Himalayan states (Jammu & Kashmir, Himachal Pradesh, Uttarakhand, Sikkim and Arunachal Pradesh) and lowland states (Uttar Pradesh, Punjab, Haryana, Bihar, Assam and West Bengal) depend on this source of water.

The recent retreat of glaciers in High Mountain Asia is a major issue for downstream communities. Similarly, glaciers in the Astore Basin are melting, causing glacial lakes to expand faster, new lakes to form, and increasing the risk of glacial lakes outburst floods (GLOFs). The present study uses Landsat data from 1993 to 2021 to explore seasonal...
Despite previous studies, glacier-lake interactions and future lake development in the Poiqu River basin,central Himalaya, are still not well understood. We mapped glacial lakes, glacier outlines, their frontal positions and ice flow from optical remote sensing data, and calculated glacier surface elevation change from digital terrain models. Durin...

Understanding moisture sources and transport mechanisms during extreme precipitation events (EPEs) is imperative for sustainable development. Here, potential moisture sources, contributions, and transport pathways were evaluated during EPEs over Tibet Plateau (TP) between 1951-2015, employing three back-trajectory approaches, including Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT), Potential Source Contribution Function (PSCF), and Concentration Weighted Trajectory (CWT). Results showed that all twenty-three selected EPEs occurred within the TP's southern foothill. Back-trajectories from the EPEs target are then clustered into five, and analysis revealed that moisture sources and pathways showed a similar pattern. Generally, moisture largely originates from three sources, including airflow trajectories from the Arabian Sea, Bay of Bengal, and tropical-subtropical area of the Indian landmass. Besides, local moisture transport within TP also has key influences. For instance, analysis from the first EPEs target showed southwesterly (Cluster 1; 12%, Cluster 2; 20%, Cluster 3; 22%) and southeasterly (Cluster 4; 30%, Cluster 5; 16%) moisture paths originating from the Arabian Sea and Northern India, respectively. Moisture transport (IVT) path analysis for this target showed that all IVT clusters in descending order were 3 > 4 > 2 > 5 > 1, with a mean of 243 kg/m/s. Conversely, above-average IVT clusters ranged from 305–345 kg/m/s and had a mean of 334 kg/m/s, while cluster 2 had the highest contribution of 37%. Moisture transport source regions obtained utilizing PSCF and CWT methods naturally share comparable features, proving the credibility and accuracy of the results. Based on the EPEs and back-trajectory analysis in this study, we demonstrated unique moisture sources and dominant moisture pathways for each EPEs target. This is important in modeling, simulating, and predicting extremes in space and time and, consequently, for resource management. This may also aid in mitigating numerous natural disasters arising from EPEs and provide significant scientific references for coordinated atmospheric research.
