Sea waves generated by extratropical cyclones in the South Atlantic Ocean: Hindcast and validation against altimeter data
This work presents analyses of the atmospheric conditions and the hindcast of the surface wave field when six extratropical cyclones formed and displaced over the South Atlantic Ocean (10degreesN, 60degreesS; 75degreesW, 15degreesE) between April and September 1999. These events caused high sea wave...
