Agulhas ring dynamics from TOPEX/POSEIDON satellite altimeter data

摘要

The transfer of warm water from the Indian Ocean into the South Atlantic subtropical gyre takes place in the form of rings and filaments formed when the Agulhas Current retroflects south of Africa between 15 and 25E. A survey of the rings formed from September 1992 until December 1995 in the Retroflection region was carried out using TOPEXPOSEIDON altimeter data.
