Spatio-temporal rainfall variability in the Amazon basin countries (Brazil, Peru, Bolivia, Colombia, and Ecuador)
Jhan Carlo Espinoza Villar,Josyane Ronchail,Jean-Loup Guyot,Gérard Cochonneau,Filizola Naziano,Waldo Lavado,Eurides de Oliveira,Rodrigo Pombosa,Philippe Vauchel +8 more
TL;DR: Rainfall variability in the Amazon basin (AB) is analyzed for the 1964-2003 period in this paper, which is based on 756 pluviometric stations distributed throughout the AB countries.
Journal ArticleDOI
Interannual rainfall variability in the Amazon Basin and sea-surface temperatures in the Equatorial pacific and the Tropical Atlantic oceans
Josyane Ronchail,Gérard Cochonneau,Michel Molinier,Jean-Loup Guyot,Adriana Goretti De Miranda Chaves,V. Guimaraes,Eurides de Oliveira +6 more
TL;DR: In this article, rainfall variability in the Amazon basin is studied in relation to sea-surface temperatures (SSTs) in the equatorial Pacific and the northern and southern tropical Atlantic during the 1977-99 period, using the HiBAm original rainfall data set and complementary cluster and composite analyses.
Journal ArticleDOI
Recent advances in wavelet analyses: Part 2—Amazon, Parana, Orinoco and Congo discharges time scale variability
TL;DR: In this article, wavelet analysis methods are applied to long-term hydrological and climatologic proxies, such as the Southern Oscillation and the North Atlantic Ocean, to suggest physical explanations for time-scale dependant relationships.
Journal ArticleDOI
Contrasting regional discharge evolutions in the Amazon basin (1974–2004)
Jhan Carlo Espinoza Villar,Jean-Loup Guyot,Josyane Ronchail,Gérard Cochonneau,Naziano Filizola,Pascal Fraizy,David Labat,Eurides de Oliveira,Juan Julio Ordoñez,Philippe Vauchel +9 more
TL;DR: In this article, the authors used a new data set including daily discharge in 18 sub-basins to analyze the variability of regional extremes in the Amazon basin, after recalling the diversity of the hydrological annual cycles within the Amazon Basin.
Journal ArticleDOI
Climate variability and extreme drought in the upper Solimões River (western Amazon Basin): Understanding the exceptional 2010 drought
Jhan Carlo Espinoza,Josyane Ronchail,Jean-Loup Guyot,Clementine Junquas,Philippe Vauchel,Waldo Lavado,Guillaume Drapeau,Rodrigo Pombosa +7 more
TL;DR: In this paper, the authors provide an initial overview of climate features and their related hydrological impacts during the recent extreme droughts (1995, 1998, 2005 and 2010) in the upper Solimoes River (western Amazon), using comprehensive in situ discharge and rainfall datasets.
