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

Abstract A glacier inventory for península Córdova, isla Riesco, Chilean Patagonia (53°14’ S, 73°00’W), has been compiled based on stereoscopic interpretation of aerial photographs March and December 1984 1:100 000 topographic maps. Three small icefields comprising 33 outlets, in addition to 12 separate glaciers, have identified, with a total area 57 km 2 . Glaciers are located mountain peaks maximum altitude 1183 mand lowermost elevation 100 m. All glaciers terminate land, except three...
The Sierra Baguales Mountain Range, forming the eastern foothills of Southern Patagonian Andes, has well-developed alpine-glaciated landforms which present an ideal opportunity to study climatic and non-climatic factors that control cirque development morphology. One hundred forty-three glacial cirques were studied with reference 14 morphometric attributes analyzed using statistical analysis GIS methodologies. classified into two types cluster complimented a composite map based on...
The mega-drought affecting the province of Cachapoal, VI Region Chile, was assessed by mapping temporal change magnitude NDVI (normalized difference index) and LST (land surface temperature) variables, retrieved from MODIS (Moderate Resolution Imaging Spectroradiometer) composite products in quinquennia last 20 years. For this purpose, current values (summer 2021) both variables were compared accordance to their quinquennial equivalents between 2001 2016 normalized regarding variability....
DPA) de la UMAG, han realizado una serie campañas glaciológicas en un sector del glaciar Tyndall denominado lóbulo Zapata Sur.Variaciones recientes este podrían estar asociadas al cambio climático que experimenta región.Se reportan resultados obtenidos desde marzo 2003 a fecha.Mediciones con sistema radio-eco sondeo permitieron estimar espesores hielo entre 63 m, cerca margen E actual glaciar, y 617 m hacia el centro distancia 2,5 km E. Mediciones GPS realizadas 5 balizas adelgazamiento...
The commune of Valparaíso, located on the central coast Chile, represents a territory interest for study impacts derived from socio-natural risks and discussion about its due inclusion in current territorial planning instruments. Particularly, Jaime ravine (quebrada Jaime), foothills coastal mountain range, an interesting site to physical configuration level anthropic intervention that occurs. In this sector, part community's low-income population has been forced migrate, scarcity urban land...
El Cambio Climático y la gestión del recurso hídrico son elementos que impactan en disponibilidad de agua una amplia gama territorios. En este trabajo se analiza el comportamiento variabilidad pluviométrica fluviométrica cuenca ríoMaule, Chile las principales mayor envergadura a nivel nacional con un área correspondiente 20.300 km2, donde predomina actividad silvoagropecuaria. Se realizó análisis clúster basado los datos disponibles para precipitaciones (periodo 2000-2019) caudales...
