“…Temperature is the most likely explanation for glacier retreat in recent decades (Kaser 1999). Furthermore, Sicart et al (2008) and Jomelli et al (2009) reported that inter-annual variability of the glacier mass balance is mainly controlled by annual variations in air temperature.…”

Most Latin American glaciers are located in the tropical Andes. The melting processes of Glacier "15" on Antisana volcano were studied to understand the relationship between glacier retreat and natural climate variability and global climate change. Glaciers on the Antisana volcano are crucial sources of water as they feed the headwater rivers that supply Quito with potable water. The aim of this study was to build empirical models based on multiple correlations to reconstruct the mass loss of glaciers over a period of 10 years at three scales: local (data recorded by meteorological stations located around the volcano), regional (data from stations located around the country) and global (re-analysis data). Data quality was checked using graphical and statistical methods. Several empirical models based on multiple correlations were created to generate longer time series (42 and 115 years) of the mass balance for the glacier ablation zone. The long mass balance series were compared with the temperature variation series of the Earth's surface in the Southern Hemisphere to estimate the relation between the mass balance and global warming. Our results suggest that the meteorological factors that best correlate with mass balance are temperature and wind.Key words Ecuador; Andes; Antisana volcano; glacier; ablation zone mass balance; empirical models Modélisation empirique du bilan de masse des glaciers tropicaux d'Amérique du Sud: cas du volcan Antisana, Equateur Résumé La plupart des glaciers d'Amérique latine sont situées dans les Andes tropicales. Les processus de fusion du glacier « 15 » sur le volcan Antisana ont été étudiés pour comprendre la relation entre le recul des glaciers et la variabilité naturelle du climat et / ou le changement climatique mondial. Les glaciers situés sur le volcan Antisana sont des ressources en eau essentielles car ils alimentent les rivières qui fournissent l'eau potable de Quito. L'objectif de cette étude était de construire des modèles empiriques sur la base de corrélations multiples afin de reconstituer la perte de masse des glaciers sur une période de dix ans à trois échelles : locale (données enregistrées par les stations météorologiques situées autour du volcan), régionales (données provenant de stations situées dans le pays) et mondiale (données de réanalyse). La qualité des données a été vérifiée à l'aide de méthodes graphiques et statistiques. Plusieurs modèles empiriques basés sur les corrélations multiples ont été créés pour générer des séries plus longues (42 et 115 ans) du bilan de masse de la zone d'ablation du glacier. La longue série de bilans de masse a été comparée à la courbe de variation de la température de surface de la Terre dans l'hémisphère Sud pour estimer la relation entre le bilan de masse et le réchauffement climatique. Nos résultats suggèrent que les facteurs météorologiques présentant la meilleure corrélation avec le bilan de masse sont la température et le vent.

“…La zona tropical de Sudamérica se puede dividir en dos sub-áreas basándose en las características de precipitación y la ubicación geográfica: los trópicos interiores (Venezuela, Colombia y Ecuador), donde la ablación y acumulación de los glaciares ocurren simultáneamente en todo el año, sin estacionalidad de las precipitaciones (VEETTIL et al 2014); y los trópicos exteriores (Perú, Bolivia y el norte de Chile), donde la estación seca se produce de mayo a septiembre, con condiciones subtropicales y la estación lluviosa de octubre a marzo, con prevalecía de condiciones tropicales (VEETTIL et al 2015(VEETTIL et al , 2016b; en esta última ocurre una acumulación notable sólo durante la temporada de lluvias (JOMELLI et al 2009 (Fig. 1).…”

“…Las erupciones más recientes se registraron en 1742-1744, 1768, 1877, 1903-1904 (BENDIX & LAUER 1992), que afectan en consecuencia, los cambios en el equilibrio de la masa. La temperatura del aire es otro factor que controla el balance de masa y el balance de energía en la región y por lo tanto es más sensible a las variaciones de la temperatura que los trópicos exteriores (FAVIER et al 2004;JOMELLI et al 2009). La incidencia de la radiación de onda corta es máxima cerca del equinoccio (Marzo-Abril a Septiembre) y si no hay precipitación sólida durante este periodo habrá una importante tasa de fusión (RABATEL et al 2013).…”

“…Estudios recientes han demostrado que los glaciares tropicales de los Andes están retrocediendo a un ritmo alarmante. El estudio del cambio climático en los Andes Tropicales utilizando glaciares como indicadores indirectos del tales variaciones ha sido discutido por muchos investigadores recientemente (VUILLE et al 2008a;JOMELLI et al 2009;VEETTIL et al 2014VEETTIL et al , 2015VEETTIL et al , 2016aVEETTIL et al , 2016b. El retroceso discontinuo de los glaciares andinos tropicales desde la Pequeña Edad de Hielo (PEH) en Ecuador, Perú y Bolivia provee una estimación de las fluctuaciones climáticas desde principios del siglo XVII (VUILLE et al 2008).…”

In this research paper, we analysed the behaviour of Tropical Andean glaciers in a changing climate. We used multi-source satellite images as well as meteorological datasets to achieve this objective. Representative glaciers in four different climatic zones, namely the inner tropics, northern wet outer tropics, southern wet outer tropics and dry outer tropics, were considered in this study. Changes in annual maximum snowline during 1985 -2015 and also the decadal changes in the area between 1975 and 2015 of these glaciers were calculated. Furthermore, we analysed the rate of glacier retreat during the occurrence of El Niño-Southern Oscillation and Pacific Decadal Oscillation. It is observed that the glaciers in both the inner and outer tropics underwent retreat during the study period and most of this retreat occurred during 1975 -1997 which is parallel with the so-called Pacific shift. Exceptional variations in snowline altitude were observed when an El Niño event occurs during the warm phase of the Pacific Decadal Oscillation. No significant signals of the recent hiatus in global warming were observed, except in the dry outer tropics which are situated near the subtropical region.

“…The central tropical Andes have been extensively studied to reconstruct glacial extent and associated timing (e.g. Coronato and Rabassa, 2007;Smith et al, 2008;Rodbell et al, 2009;Jomelli et al, 2009). However, glaciations knowledge in the northern tropical Andes is limited.…”
