Abstract

The spatial distribution of the energy balance and the rotation of the Earth cause zonal atmospheric circulation patterns. The South American Andes are an almost uninterrupted N-S stretching barrier to these main currents, reaching from the tropics into the trade winds, the westerlies and the subantarctic circulation patterns and causing more or less sharp climate contrasts. Consequently, glacier mass balance regimes vary within short E-W distances and the related glacier fluctuations provide a highly informative tool for studying present and past atmospheric circulation systems. First studies on this matter from the Cordillera Blanca, Perú, show the possibilities of climate-glacier studies in the Andes. In addition, the present paper proposes the design of a large scale and long-term mass balance program on the Southern Patagonia Icefield.
