Simulation of Long-Term Changes of the Equilibrium Line Altitude in the Central Chilean Andes Mountains Derived From Atmospheric Variables During the 1958–2018 Period

Annual variability and trends of the Equilibrium Line Altitude (ELA) in the Andes mountains can be studied using the annual average of the 0°C isotherm altitude (ZIA) and the annual precipitation accumulation in mountains areas. Carrasco et al. (2005, 2008) obtained the ELA along the western side of the Andes from about 18°S to 55°S, using the radiosonde data from the Chilean areological stations located at Antofagasta (23°26° S, 70°26°W;...
