Future changes of precipitation types in the Peruvian Andes.

In high-altitude regions, such as the Peruvian Andes, understanding the transformation of precipitation types under climate change is critical to the sustainability of water resources and the survival of glaciers. In this study, we investigate the distribution and types of precipitation on a tropical glacier in the Peruvian Central Andes. We utilized data from an optical-laser disdrometer and compact weather station installed at 4709 m ASL, combined with future climate scenarios from the CMIP6 project, to model potential future changes in precipitation types.

Projections of the future disappearance of the Quelccaya Ice Cap in the Central Andes.

We analyze the future state of Quelccaya Ice Cap (QIC), the world's largest tropical ice cap with a summit elevation of 5680 m a.s.l.
