A weather numerical prediction system and the oceanic weaves to South Atlantic

A coupled weather and sea waves forecast system is presented to be applied operationally on the South Atlantic region. This system is compounded by one atmospheric limited area model (LAM) and two nested wind generated surface sea wave models: the gross mesh model (SWGM) and the fine mesh model (SWFM). The SWGM covers an area of 10 super(6) Km super(2) roughly, and aims to generates and propagates sea waves far away from the Brazilian Coast. The SWFM is one way nested into SWGM in a domain of 10 super(4) Km super(2) with a fine bathymetric structure included. Both sea wave models use the time and spatial files of the 10 m height wind produced by LAM as the atmospheric forcing.
