Abstract
dc.description.abstract
Seasonal snow and glaciers in arid mountain regions are essential in sustaining human populations,
economic activity, and ecosystems, especially in their role as reservoirs. However, they are
threatened by global atmospheric changes, in particular by variations in air temperature and their effects
on precipitation phase, snowdynamics andmass balance. In arid environments, small variations in snow
mass and energy balance can produce large changes in the amount of available water. This paper
provides insights into the impact of global warming on the mass balance of the seasonal snowpack in
the mountainous Copiapó river basin in northern Chile. A dataset from an experimental station was
combined with reanalysis data to run a physically based snow model at site and catchment scales.
The basin received an average annual precipitation of approximately 130 mm from 2001 to 2016,
with sublimation losses higher than 70% of the snowpack. Blowing snow sublimation presented
an orographic gradient resultant from the decreasing air temperature and windy environment in
higher elevations. Under warmer climates, the snowpack will remain insensitive in high elevations
(>4000 m a.s.l.), but liquid precipitation will increase at lower heights.
