Impact of Hindu Kush Himalayan snow cover change on Monsoon Circulation

Mountain snow cover is an integral part of our climate system that impacts ecosystems and the biosphere that rely on river systems. In recent years, the Hindu Kush-Himalayan regions have experienced a significant decline in snow cover, which is primarily attributed to global warming. However, understanding the nonlinear trends associated with these changes remains a challenge. Here, we explore the relationship between snow cover change and monsoon dynamics within the context of a changing climate, specifically examining the role of land-atmosphere interaction. The study's findings reveal a clear connection between the declining snow cover and monsoon circulation, which is explained through multiple models and grounded in mean state changes. This result highlights the crucial role of snow cover in the dynamics of monsoon.
