Dry season circulation-type classification applied to precipitation and temperature in the Peruvian Andes
Bonshoms, Marti; Álvarez‐Garcia, Francisco J.; Ubeda, Jose; Cabos, William; Quispe Vega, Kelita; Liguori, Giovanni
(John Wiley and Sons, 2020-04-07)We present the first systematic classification of circulation regimes that characterize the Tropical Andes during the dry season (May–August). We apply the hierarchical k-means clustering method to ERA-Interim reanalysis ... -
Impacts of land use on the hydrological response of tropical Andean catchments
Ochoa-Tocachi, B.F.; Buytaert, W.; De Bièvre, B.; Célleri, R.; Crespo, P.; Villacís, M.; Llerena, C.A.; Acosta, L.; Villazón, M.; Guallpa, M.; Gil-Ríos, J.; Fuentes, P.; Olaya, D.; Viñas, P.; Rojas, G.; Arias, S.
(John Wiley and Sons Ltd, 2016-08-30)Acceso abiertoChanges in land use and land cover are major drivers of hydrological alteration in the tropical Andes. However, quantifying their impacts is fraught with difficulties because of the extreme diversity in meteorological ... -
Mechanisms of tropical precipitation biases in climate models
Kim, Hanjun; Kang, Sarah M.; Takahashi, Ken; Donohoe, Aaron; Pendergrass, Angeline G.
(Springer, 2020-10-27)We investigate the possible causes for inter-model spread in tropical zonal-mean precipitation pattern, which is divided into hemispherically symmetric and anti-symmetric modes via empirical orthogonal function analysis. ... -
Revisiting wintertime cold air intrusions at the east of the Andes: propagating features from subtropical Argentina to Peruvian Amazon and relationship with large-scale circulation patterns
Espinoza, J.C.; Ronchail, Josyane; Lengaigne, Matthieu; Quispe, Nelson; Silva, Yamina; Bettolli, Maria Laura; Avalos, Grinia; Llacza Rodríguez, Alan
(Springer, 2012-12-29)Acceso abiertoThis study investigates the spatial and temporal characteristics of cold surges that propagates northward along the eastern flank of the Andes from subtropical to tropical South America analysing wintertime in situ daily ... -
The role of ENSO flavours and TNA on recent droughts over Amazon forests and the Northeast Brazil region
Jimenez, Juan C.; Marengo, José A.; Alves, Lincoln M.; Sulca, Juan; Takahashi, Ken; Ferrett, Samantha; Collins, Matthew
(Royal Meteorological Society, 2019-12-27)Acceso restringidoAmazon tropical forests and the semiarid Northeast Brazil (NEB) region have registered very severe droughts during the last two decades, with a frequency that may have exceeded natural climate variability. Severe droughts ... -
Soluble trace metals in aerosols over the tropical south-east Pacific offshore of Peru
Baker, A.R.; Thomas, M.; Bange, H.W.; Plasencia Sanchez, E.
(Copernicus GmbH, 2016)Acceso abiertoMeteor cruise M91 was supported by the BMBF projects SOPRAN II and III (FKZ 03F0611A and FKZ 03F662A). We thank the Peruvian authorities for authorising us to conduct the study in their territorial waters. We also would ... -
Spatio-temporal patterns of thermal anomalies and drought over tropical forests driven by recent extreme climatic anomalies
Jimenez, Juan C.; Barichivich, Jonathan; Mattar, Cristian; Takahashi, Ken; Santamaría-Artigas, Andrés; Sobrino, José A.; Malhi, Yadvinder
(The Royal Society, 2018-08-23)The recent 2015– 2016 El Niño (EN) event was considered as strong as the EN in 1997–1998. Given such magnitude, it was expected to result in extreme warming and moisture anomalies in tropical areas. Here we characterize ...
