Investigation of the interannual variability of the Tropical Atlantic Ocean from satellite data Arnault Sabine auteur aut IRD Mélice Jean-Luc auteur aut IRD text journalArticle eng text/pdf born digital access The interannual variability of the tropical Atlantic Ocean is analyzed from 1992 to 2011 using statistical decompositions of different satellite data such as altimetric series. Three regions of maximum variability are highlighted: a northern one, between 10 and 20 degrees N; a southern region, along 20 degrees S; and an equatorial region. This variability is due to both local and remote wind activity. The teleconnections with the tropical Pacific El NinoSouthern Oscillation indicate a possible connection of the tropical Atlantic between 10 and 20 degrees N with a 4-month delay, and in the Gulf of Guinea with a 16-month delay. specialized Tropical Atlantic altimetry interannual variability OCEAN ATLANTIQUE ZONE TROPICALE 032 126 021 Marine Geodesy 35 1 151-174 2012 0149-0419 https://www.documentation.ird.fr/hor/fdi:010058861 10.1080/01490419.2012.718212 0149-0419 [F B010058861] https://www.documentation.ird.fr/hor/fdi:010058861 https://www.documentation.ird.fr/intranet/publi/2013/02/010058861.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2013-03-06 2017-08-23 fdi:010058861 fre
