Description

The Atmospheric Turbulence and Diffusion Division (ATDD) of the National Oceanic and Atmospheric Administration (NOAA) and the Divisao de Seguranca Ambiental (DSEA.N) of Furnas Centrais Eletricas S.A. (FURNAS) have undertaken a joint field study to characterize atmospheric transport and diffusion at the complex site of the Angra Nuclear Power Plant (Angra 1) operated by FURNAS. Phase 1 experiments were designed to address questions of site representativeness with respect to the present meteorological monitoring system. Experiment teams undertook two week intensive measurement program consisting of tethersonde sounding coupled with neutral-lift balloon tracking. The data showed the site meteorology to be dominated by the local land/sea breeze effects. Daytime trajectories follow the local onshore flow until ridge top then indicate transport out to the ocean. Trajectories during the evening hours followed the drainage flow out to sea ending some distance from the shore or showing a tendency to follow the upper level onshore flow. (Author)

Abstract (Portuguese)

Atmospheric Turbulence and Diffusion Division (ATDD) da National Oceanic and Atmospheric Administration (NOAA) e a Divisao de Seguranca Ambiental (DSEA.N) de FURNAS - Centrais Eletricas S.A. (FURNAS) realizaram um experimento de campo em conjunto para caracterizar o transporte e a difusao atmosferica no complexo local da usina nuclear de Angra (Angra 1) operada por FURNAS. Os experimentos da Fase 1 objetivaram enderecar questoes de representatividade local com respeito ao sistema de monitoracao meteorologica atual. Os grupos de campo realizaram um programa intensivo de medidas de duas semanas consistindo de sondagem cativa acoplada a rastreamento de baloes neutros. Os dados mostraram que a meteorologia local e dominada por efeitos de brisa marinha/terrestre. As trajetorias diurnas seguem o fluxo marinho ate a crista dos morros, quando entao indicam transporte na direcao do mar. As trajetorias noturnas seguem o fluxo de drenagem para o mar, morrendo em algun ponto distante da costa ou mostrando uma tendencia a retornar para a terra no fluxo marinho superior. (Autor)
