Abstract. To better characterize the climate variability of last millennium in high Andes, we analyzed pollen content a 1150-yr-old sediment core collected bog located at 3800 m a.s.l. páramo eastern Cordillera Ecuador. An upslope convective index based on ratio between cloud transported from Andean forest to (T) and Poaceae frequencies, related edaphic moisture (P), was defined. This used distinguish changes atmospheric soil their associated patterns interdecadal El Niño–Southern...
Abstract. The influence of El Niño and La Niña on monthly seasonal rainfall over mountain landscapes in Colombia México was assessed based the Oceanic Index (ONI). A statistical analysis develop to compare extreme dry/precipitation events between Niño, Neutral episodes. For both areas, it observed that episodes are associated with important increases or decreases rainfall. However, showed highest occurrence precipitation/dry events. a better understanding impact precipitation, we did...
Abstract. To better characterize the climate variability of last millennium in high Andes, we analysed pollen content a 1100-yr-old sediment core collected bog located at 3800 m a.s.l. páramo Eastern Cordillera Ecuador. An upslope convective index based on ratio between cloud transported from andean forest to (T) and Poaceae frequencies, related edaphic moisture (P), was defined distinguish atmospheric soil páramo. Results showed that 900 AD 1230 AD, Medieval Climate Anomaly interval warm...
