Tropical Atlantic Variability Conference in Cape Town [fr]

Ocean Climate variability has important socio-economic consequences on continental climate (droughts and floods) and fluctuations in marine ecosystems and Fisheries. Our understanding of ocean climate variability in the Tropical Atlantic and its impacts is limited, and our ability to simulate and predict it is poor. Recognising this, the EU FP7 PREFACE “Enhancing Prediction of Tropical Atlantic Climate and its Impacts”, PIRATA “Prediction and Research Moored Array in the Tropical Atlantic” and the CLIVAR Atlantic communities jointly organised the 2015 Conference on Ocean, Climate and Ecosystem in Cape Town (South Africa) from 25 to 27 August 2015, gathering 90 international scientists and experts from 25 countries.


Additional internal CLIVAR Atlantic panel, PREFACE and PIRATA meetings and workshops were held that week. T

he meeting was organised by Mathieu Rouault, Emlyn Balarin and Sharon Bosman from the Nansen Tutu Centre for Marine Environmental Research and the MA-Re Institute of University of Cape Town and Mahaut de Vareilles, Mandy Kong and Noel Keenlyside from University of Bergen, Norway.

There were 90 delegates from 25 countries that attended the Conference. This was a COP21 side event and co-sponsorship was secured by IRD and the SCAMPI NRF bilateral project between Norway and South Africa. More info and presentations are available on the conference and Preface websites.


Further information on the projects:

PREFACE "Enhancing prediction of Tropical Atlantic climate and its impacts" is a climate change project with 28 partners across 18 countries in Europe and Africa, and 3 associate partners directly involved in the sustainable management of the three Eastern boundary large marine ecosystems of the Tropical Atlantic. PREFACE is funded by the European Union’s Seventh Framework Programme.

PIRATA"Prediction and Research Moored Array in the Tropical Atlantic" is a program designed to study ocean-atmosphere interactions in the tropical Atlantic that affect regional climate variability on seasonal, interannual and longer time scales. The array was originally developed in the mid-1990s and has undergone extensions and enhancements since 2005 to improve its utility for describing, understanding, and predicting societally relevant climate fluctuations. PIRATA has been implemented through multi-national cooperation in support of CLIVAR, GOOS, GCOS, and GEOSS. Financial, technical and logistic support is provided by France (IRD in collaboration with Meteo-France, CNRS and IFREMER), Brazil (INPE and DHN) and the USA (NOAA). Data are freely available for research and operational applications via the World Wide Web and the Global Telecommunications System.

CLIVAR "Climate and Ocean: Variability, Predictability and Change" is one of the four core projects of the World Climate Research Programme (WCRP). CLIVAR’s mission is to understand the dynamics, the interaction, and the predictability of the coupled ocean-atmosphere system. To this end it facilitates observations, analysis and predictions of changes in the Earth’s climate system, enabling better understanding of climate variability and dynamics, predictability, and change, to the benefit of society and the environment in which we live.
