Tropical instability waves in the atlantic-ocean - a contributor to biological processes
Provedor de dados: 5
Autores: Morliere, A; Lebouteiller, A; Citeau, J.
Long tropical instability waves are described at around 3-4 degrees N based on results of a simulation performed with a general circulation model for the Atlantic Ocean. This description is in agreement with earlier observations of organized undulations of the summer thermal front associated with anti-cyclonic eddies propagating westward at 30-40 km/day along 3-4 degrees N from 10 to 40 degrees W through the Atlantic basin. However, the simulation indicated the presence of long waves in early boreal winter. In this respect, satellite observations during short cold events in winter show thermal front undulations similar to those associated with long wave propagations. The simulation clearly demonstrated large vertical movements between the surface and a...

[1] The equatorial Pacific and Atlantic oceans exhibit remarkable meridional undulations in temperature and chlorophyll fronts visible from space over thousands of kilometers and often referred to as tropical instability waves. Here, we present new observations of an ecosystem ranging through three trophic levels: phytoplankton, zooplankton and small pelagic fish whirling within a tropical vortex of the Atlantic ocean and associated with such undulations. Cold, nutrient and biologically rich equatorial waters are advected northward and downward to form sharp fronts visible in all tracers and trophic levels. The equatorward recirculation experiences upwelling at depth, with the pycnocline and ecosystem progressively moving toward the surface to reconnect...
