Evolution du débit de l’Amazone à Óbidos de 1903 à 1999 / Evolution of the River Amazon’s discharge at Óbidos from 1903 to 1999

Autor: Eurides de Oliveira, Josyane Ronchail, Jean-Loup Guyot, Hélène Niel, Jacques Callède, Yann L'Hôte

Publikováno v: Hydrological Sciences Journal. 49:85-97

The time series of 97 annual values, observed or reconstituted, of runoff of the River Amazon at Obidos shows a slight increase of 9% in the mean annual discharges from 1903 to 1999, and of 10% for the floods. All the rupture tests indicate a break i

Archives, histoire du climat et pluviométrie : un exemple sud-américain

Autor: Yann L'Hôte, Alain Gioda

Publikováno v: La Houille Blanche. 88:44-50

The aim of this research is to reconstruct a regional history of climate, and particularly rainy seasons, using first of all printed chronicles, travellers and explorers diaries and press information. We secondly study archival documents to have a cl

Analysis of a Sahelian annual rainfall index from 1896 to 2000; the drought continues

Autor: Gil Mahé, Bonaventure Some, Jean Pierre Triboulet, Yann L'Hôte

Publikováno v: Hydrological Sciences Journal. 47:563-572

Since 1970 the West African Sahel has experienced a significant drought which, according to some authors, corresponds to a discontinuity (abrupt change) in the rainfall series. An annual rainfall index was calculated over the period from 1896 to 2000

Trends and discontinuities in regional rainfall of West and Central Africa: 1951–1989

Autor: Geoffroy Wotling, Yann L'Hôte, Jean Claude Olivry, Gil Mahé

Publikováno v: Hydrological Sciences Journal. 46:211-226

Standardized regional mean annual rainfall series are analysed over the period 1951–1989 from a data set of 891 rainfall stations which covers 23 countries of West and Central Africa. Missing values are estimated by using regionalized indexes compu

Abstract The knowledge of the precipitation phase, solid or liquid, is important in high mountains, in order to use models of water and energy balances. During an experiment led in the Bolivian Andes, a complete weather station was installed at an al

Determining the precipitation phase—rain or snow—is an important factor in modelling discharge in mountainous basins. In a study carried out in the outer tropical Andes Cordillera of Bolivia, half-hourly determination of precipitation phase was o
