Mountain Climate Drivers
• Different weather patterns produce precipitation• Remote sensing gives data from ~1980-present, trends
emerge, but cannot predict future change• Station data (pre-1980) / measurements are sparse in
remote locations
Winter Storms
Summer Monsoons
Max Precipitation Season, TRMM Satellite
Station Locations 1998Yatagi et al., BAMS, 2012
1998-2007

Current Major U.S. Effort: NASA High Mountain Asia Team• 3 year award from NASA Earth Sciences (2017-2019)• Goal: to advance understanding of processes driving
changes in climate and the cryosphere in the High Mountain Asia region
• 14 teams funded, 90 individual members• Interdisciplinary effort to bring together glaciologists,
hydrologists, climate scientists, hazard specialists, social scientists, applications
