标题：Local and Regional Features of Surface Radiation Fluxes Over the Tropical Atlantic Ocean Near Sao Pedro and Sao Paulo Archipelago: Evidence of Small Scale Upwelling
摘要：To properly describe the interactions between the ocean and atmosphere, it is necessary to assess a varietyof time and spatial scales phenomena. Here, high resolution oceanographic and meteorological data collectedduring an observational campaign carried out aboard a ship in the tropical Atlantic Ocean, on May 15-24,2002, is used to describe the radiation balance at the ocean interface. Data collected by two PIRATA buoys,along the equator at 23ºW and 35ºW and satellite and climate data are compared with the data obtainedduring the observational campaign. Comparison indicates remarkable similarity for daily and hourly values ofradiation fluxes components as consequence of the temporal and spatial consistence presented by the airand water temperatures measured in situ and estimated from large scale information. The discrepancy,mainly in the Sao Pedro and Sao Paulo Archipelago area, seems to be associated to the local upwelling ofcold water, which is not detected in all other estimates investigated here. More in situ data are necessary toclarify whether this upwelling flow has a larger scale effect and what are the meteorological and oceanographicimplications of the local upwelling area on the tropical waters at the Brazilian coast.
