Objectif

Les tourbillons océaniques à méso-échelle créent des modes d'interaction air-mer spécifiques qui peuvent avoir un effet intégral sur l'atmosphère et la dynamique océanique à grande échelle. Les progrès récents dans l'état de l'art de ces processus ont été principalement obtenus grâce aux efforts de modélisation, mais il n'existe que très peu d'études observationnelles, et elles sont toutes situées dans les régions extra-tropicales. L'ajout d'une étude expérimentale dédiée aux interactions à la méso-échelle océanique à la campagne aéroportée EUREC4A permettra d'améliorer les objectifs et le succès de l'ensemble du programme en établissant une contrainte océanique locale à l'évolution atmosphérique (comme indiqué dans la conception globale de EUREC4A: Bony et al. 2017). La variabilité temporelle sur une zone d'étude à méso-échelle fixe (500 km x 500 km) permet d'échantillonner différents états atmosphériques, sur les échelles de temps de EUREC4A. La composante océanographique qui s'ajoute à EUREC4A consiste en quatre navires échantillonnant l'océan à méso-échelle et les échanges air-mer à quatre bords différents de la région ciblée par EUREC4A. Cela permettra un échantillonnage spatial étendu qui est nécessaire pour caractériser la variabilité de l'océan et recueillir suffisamment d'observations air-mer sur différentes zones pour évaluer avec précision les processus et les impacts impliqués.

L'Atlantique tropical occidental est un laboratoire idéal pour l'étude proposée. Elle abrite une riche variabilité océanique à méso-échelle (et à sous méso-échelle) dans une atmosphère caractérisée par un régime d'alizés assez stable. Dans cette région, les tourbillons océaniques ont un diamètre de 200 à 300 km et une durée de vie de plusieurs mois à des années. En particulier, au sud de la Barbade, on trouve couramment des tourbillons anticycloniques très énergiques et de longue durée provenant du Courant du Brésil Nord. Ces tourbillons sont essentiels pour le transport vers le l'Atlantique Nord des masses d'eau provenant de l'Atlantique Sud et qui constituent un élément essentiel de l'Atlantique Meridional Overturning Circulation (AMOC). De plus, des études préliminaires basées sur des observations satellitaires suggèrent que ces tourbillons jouent un rôle crucial dans les interactions air-mer et dans l'atmosphère. C'est spécifiquement dans cette région spécifique de l'Atlantique Tropical Nord et sur ces tourbillons de méso-échelle que se focalisera la campagne EUREC4A-OA.
