Indian Ocean Crossing Swells: New Insights from “Fireworks” Perspective Using Envisat Advanced Synthetic Aperture Radar

Synthetic Aperture Radar (SAR) in wave mode is a powerful sensor for monitoring the swells propagating across ocean basins. Here, we investigate crossing Indian Ocean using 10-years Envisat SAR archive spanning from December 2003 to April 2012. Taking benefit of unique “fireworks” analysis on observations, reconstruct origins and routes that are associated with swell pools Ocean. Besides, three different mechanisms discriminated space by comparative between results original data: (1) mid-ocean basin Ocean, two remote southern form swell; (2) wave-current interaction; and, (3) co-existence Southern shamal contribute Agulhas Current region Arabian Sea.
