“…Rupture entre 1960 et 1979. Par ailleurs, il n'a pas été possible d'identifier une relation systématique à l'échelle interannuelle entre les phénomènes ENSO (QUINN et al, 1987 ;MORON, 1994) et la succession des périodes sèches et humides observée en Afrique de l'Ouest et Centrale. Seule la concomitance entre l'ENSO très important observé en 1982-1983 et une année particulièrement déficitaire enregistrée dans cette région en 1983 a pu être mise en évidence.…”

Si les causes premières d'apparition du phénomène sont, à l'heure actuelle, encore insuffisamment expliquées, et ce même si certaines activités humaines y ont, sans aucun doute, contribué, cette baisse de la pluviométrie a, bien entendu, des conséquences importantes sur la disponibilité des ressources en eau dans ces régions. Si la carence pure et simple n'est pas à craindre dans ces régions où les quantités précipitées restent importantes dans l'absolu, les effets de cette variabilité climatique peuvent, malgré tout, se révéler désastreux, en ce sens qu'ils modifient les données d'un équilibre déjà souvent mis à mal par ailleurs (pression anthropique et déforestation par exemple).

“…9. Biennial Australian Great Barrier Reef coral C values (detrended with respect to a third-order polynomial "t) plotted with incidences of strong and very strong ENSO events before AD 1800 and including medium ENSO events after AD 1800 (plotted biennially) as reported by Quinn et al (1987). Solid peaks represent correlation between ENSO events and coincident ($2}4 yr) C lows, stippled areas represent correlation between ENSO events and coincident C highs, and open areas indicate no correlation (from Dru!el and Gri$n, 1993).…”

Corals o!er a rich archive of past climate variability in tropical ocean regions where instrumental data are limited and where our knowledge of multi-decadal climate sensitivity is incomplete. In the eastern equatorial Paci"c, coral isotopic records track variations in ENSO-related changes in sea-surface temperature; further west, corals record variability in sea-surface temperature and rainfall that accompanies zonal displacement of the Indonesian Low during ENSO events. These multi-century records reveal previously unrecognised ENSO variability on time scales of decades to centuries. Outside the ENSO-sensitive equatorial Paci"c, long-term trends towards recent warmer/wetter conditions suggest the tropics respond to global forcings. New coral paleothermometers indicate that surface-ocean temperatures in the tropical southwestern Paci"c were depressed by 4}63C during the Younger Dryas climatic event and rose episodically during the next 4000 yr. High temporal-resolution measurements of Sr/Ca and O in corals provide information about the surface-ocean hydrologic balance and can resolve the seasonal balance between precipitation and evaporation. Radiocarbon measurements in corals, coupled with ocean circulation models, may be used to reconstruct near-surface ocean circulation, past mixing rates, and the distribution of fossil fuel CO in the upper ocean. Most recently, seasonal to interannual variations in the radiocarbon of corals from the equatorial Paci"c have been linked to the redistribution of surface waters associated with the ENSO.

“…The El Niñ o-Southern Oscillation (ENSO) is one such important large-scale climate disturbance occurring irregularly at intervals of 3-12 years (Quinn et al, 1987). Moreover, ENSO climate anomalies are superimposed over more regionally characteristic large-scale atmospheric patterns such as regional monsoon systems.…”
