In the recent HinduKush Himalaya Assessment published by ICIMOD, a regional intergovernmental learning and knowledge sharing centre, the increased risk from natural natural hazards like floods, landslides, avalanches, droughts and earthquakes due to global climate change for Himalayan communities is highlighted. Such natural hazard is already occurring in Leh, a himalayan town in Ladakh, Northern India. Since the last two decades, Leh is experiencing an increase in hydrological disasters in the form of cloudburst and flash floods. The 2010 cloudburst and it’s subsequent flash flood received the most media attention however, it is one of many extreme precipitation events occurring in the region. Despite the growing importance, there’s a lack of scientific study that attempts to understand the region’s changing climate. Therefore this paper studies the changing precipitation pattern in the region using daily precipitation data from Integrated Multi-satellitE Retrievals for GPM (Global Precipitation Model). Using Mann Kendall trend test, an increasing trend in daily mean precipitation is observed in the region. However, no significant trend is observed for extreme precipitations happening in the region.
