Abnormal bloom of phytoplankton around 10°N in the western Pacific during the 1982-83 ENSO IRD
Dandonneau, Yves.
The chlorophyll concentration at the surface of the tropical Pacific has been monitored through the 1982-83 ENSO, owing to the SURTROPAC ships of opportunity network. The event was characterized by a decrease in chlorophyll concentrations at the equator, where a belt of relatively rich water however persisted. The most striking anomaly was observed in the western Pacific between 5°N and 15°N. In this region, chlorophyll at the surface is generally less than O.O7 mg m-3, caused by a mixed layer exhausted in nutrients and by strong density gradient in the thermocline. From october 1982 to march 1983, higher concentrations up to 0.70 mg m-3 have been recorded by the network. This is consistent with the shallowing of the thermocline which characterizes all...

Air-sea interaction in the western tropical Pacific ocean during 1982/83 and 1986/87 IRD
Meyers, G.; Bailey, R.; Lindstrom, E.; Phillips, H..
The Southern Oscillation Index (SOI), equatorial zonal wind, sea level anomalies at islands, sea surface temperature at Puerto Chicama Peru and mixed layer temperature and depth from the XBT ship of opportunity network are used to describe conditions during the past two ENSO episodes. Onset of sustained ENSO anomalies in the 1986/87 episode was in July 1986, one month later in the year onset of the 1982/83 episode in June 1982. Both episodes of the 1980's the usual surface temperature difference along the equator between 165°W and 160°E reversed and rapidly increased to 1°C in the order direction. ENSO warming of the central Pacific tends to be confined to the region 10°N-10°S whereas cooling of the western Pacific occurs in a broader region from...

AN ANALYSIS OF THE IMPACT OF ENSO (EL NINO/SOUTHERN OSCILLATION) ON GLOBAL CROP YIELDS AgEcon
Ferris, John N..
Forecasts of global crop yields prior to planting have generally been single values, based entirely on past trends. Regression analysis testing a combination of data from ENSO (El Niño/Southern Oscillation) and ARMA models suggests that yield forecasting errors can be reduced, generating more normal distributions of these errors. Keywords: El Niño, ENSO, forecasting crop yields, long range weather forecasting, agricultural modeling, food security, risk management
Tipo: Working or Discussion Paper Palavras-chave: El Niño; ENSO; Forecasting crop yields; Long range weather forecasting; Agricultural modeling; Food security; Risk management; Crop Production/Industries.

Balanço hídrico da Bacia do Alto Paraguai por meio de dados TRMM e MOD16A2. Repositório Alice
MACEDO, H. de A.; STEVAUX, J. C.; SILVA, A.; BERGIER, I..
O armazenamento de água de uma bacia de drenagem determina sua segurança hídrica. A quantidade de água retida na bacia pode ser medida por meio do cálculo do balanço hídrico, definido pela entrada de água subtraída das saídas. As medidas de entrada e saída hídrica em uma bacia de drenagem são onerosas, o que torna o uso de dados de sensoriamento remoto uma ferramenta de grande impacto socioeconômico para este fim. Somado a isto, tem-se que estudos de disponibilidade hídrica com sensores orbitais são relativamente escassos para a Bacia do Alto Paraguai (BAP). Dessa forma, a partir do processamento de dados de precipitação do Tropical Rainfall Measuring Mission (TRMM) e de evapotranspiração do MODIS Global Evapotranspiration Project (MOD16), o presente...

Climate Effects on Rainfall Index Insurance Purchase Decisions AgEcon
Novak, James L.; Nadolnyak, Denis A..
Rainfall Index insurance is a pilot insurance product offered to producers of hay and pasture in 9 states. This analysis examines the expected payoff of the RI insurance for bi-monthly periods based on rainfall shortage probabilities in alternative climate phases. Differences in expected returns indicate that selection of ENSO-specific optimal intervals may result in higher returns than those based on pooled rainfall series.

Convection and circulation anomalies over the oceanic warm pool during 1981-1982 IRD
Weickmann, K.M..
An important issue in understanding the low frequency evolution of the atmospheric circulation and the ocean-atmosphere system is the role of transients during individual events. We examine this question from an observational point-of-view for two different time scales and speculate on the importance of transients from these two different perspectives. Our analysis period covers September 1981 - April 1982 which includes the development phase of the 1982-83 El Nino Southern Oscillation (ENSO) as well as six Madden-Julian (30-60 day) Oscillations (MJO). The latter include a strong event during december 1981 that is studied in detail. The self-similarity of these two time scales (Webster, 1989) is also highlighted. (Résumé d'auteur)

Designing Rainfall Insurance Contracts for Pasture, Rangeland, and Forage AgEcon
Nadolnyak, Denis A.; Vedenov, Dmitry V..
In the paper, preliminary results of the analysis of potential use of climate forecast information in designing rainfall index insurance in the southeastern region of the U.S. are reported. Joint distributions of bi-monthly rainfall and El Nino Southern Oscillation (ENSO) indexes are estimated using copula analysis of historical data. The risk reducing effectiveness of introducing premiums conditional on ENSO forecast is evaluated. The results indicate some dependence of the downward volatility of rainfall on the lagged ENSO (forecast) index, particularly in the coastal areas and in the late winter and spring.

Determinants of Farmers' Resilience towards ENSO-Related Drought: Evidence from Central Sulawesi, Indonesia AgEcon
Keil, Alwin; Zeller, Manfred; Wida, Anastasia; Sanim, Bunasor; Birner, Regina.
Crop production in the tropics is subject to considerable climate variability caused by the El Nino-Southern Oscillation (ENSO) phenomenon. In Southeast Asia, El Niño causes comparatively dry conditions leading to substantial declines of crop yields. In concert with global warming, the frequency and severity of the phenomenon are likely to increase during the 21st century. Little is known about the impact of ENSO-related drought on the welfare of farm households in developing countries. This paper seeks to contribute to closing this knowledge gap with a case study from Central Sulawesi, Indonesia. Its objective is to measure household resilience towards drought periods and identify its influencing factors to deduce policy implications. Using...

Eastern Tropical Pacific Climate And El Niño Variability During The Past Millennium ArchiMer
Rustic, Gerald Thomas.
The El Niño Southern Oscillation (ENSO) has been implicated in large-scale climate shifts of the past millennia, but paleoclimate records from the dynamically vital eastern equatorial Pacific Ocean (EEP) spanning the past millennium are sparse. This has limited our understanding of tropical Pacific dynamics, leaving questions regarding the source of ENSO variability unanswered. Here I seek to address some of these questions regarding relationship between ENSO and tropical Pacific mean state, and the relationship between the tropical Pacific and large-scale climate. Mean EEP sea surface temperature (SST) for the past millennium was reconstructed using Mg/Ca ratios in Globigerinoides ruber from a sub-centennially resolved sediment core collected near the...

Ecology of small terrestrial mammals in an isolated Cerrado patch, eastern Paraguay: communities, species, and effects of enso, precipitation, and fire Mastozool. neotrop.
Owen,Robert D.
The Cerrado extends as islands or patches into the Upper Paraná Atlantic Forest (UPAF) of Brazil and Paraguay. This study evaluates the temporal dynamics of a marginal terrestrial small-mammal community in an isolated Cerrado patch within the UPAF, at the southwestern distributional limit of the Cerrado and near the western limit of the UPAF in eastern Paraguay. Because the faunal members of marginal communities are living near the limits of their capabilities in terms of their abiotic and biotic environment, the communities in such areas are likely to be a mixture of Cerrado and UPAF species, sensitive to extrinsic variables such as climate change and anthropogenic changes in land use. In this 23-month study, temporal dynamics of a terrestrial...

Effect of low latitude Western boundary gaps on the reflection of Equatorial motions IRD
Penhoat, Yves du; Cane, M.A..
The Western Tropical Pacific is thought to be an important zone for generating El Nino : reflections at the boundary make it a potential source region of Equatorial Kelvin waves. Calculations of the effect of a gappy Western boundary on the reflection process are carried out in the framework of the low frequency limit of the shallow water equations and are highly idealized. The method is also applied to a schematic version of the flow through the Indonesian seas from the Western Pacific to the Indian oceans. The results indicate somestrong sensitivities to the location of the gap and to the structure of the incoming flows. In addition, the results can be quite different, depending on whether the zonal extend of the gap is assumed to be infinite or finite....
