Resumen / Abstract.

We use meteorological data from two automatic weather stations (AWS) on Juncal Norte Glacier, central Chile, to investigate theglacier–climate interaction and to test ablation models of different complexity. The semi-arid Central Andes are characterized by dry summers, with precipitation close to zero, low relative humidity and intense solar radiation. We show that katabatic forcing is dominant both on the glacier tongue and in the fore field, and that low humidity and absence of clouds cause strong radiative cooling of the glacier surface.
