Resumo

Baseado em dez anos de dados de direção e velocidade de vento da Estação Meteorológica Automática de Superfície (EMAS), foi caracterizado o regime de vento em superfície em Seropédica, Estado do Rio de Janeiro (RJ). Foram elaborados histogramas e rosas do vento decenal, sazonal e por períodos (madrugada, manhã, tarde e noite). As direções predominantes decenais foram N e SW, sendo associadas ao regime de brisa de vale/montanha e brisa marítima, juntamente com a passagem de Sistemas Frontais. As classes de vento decenal foram calmaria (abaixo de 1 m. s–1) (40,2%) e ventos fracos (1 a 3 m.s–1) (39,8%). Sazonalmente, as direções predominantes foram N, NW, NNE, SSW e SW (Outono); N, NNW, NE, SW e N (Inverno); N, NNE e SSW (Primavera), e N, NNW, SW e SSW (Verão). As predominâncias por períodos foram nas direções N, NW e SSW (Madrugada); N, NNW e NW (Manhã); N, NNE, S e SW (Tarde), e S, SW e SSW (Noite).

Abstract

In this study, we characterize the surface wind regime in the municipality of Seropedica, Rio de Janeiro state, Brazil, based on 10 years of data on wind direction and speed collected by an Automated Surface Weather Station (ASWS). Histograms and wind roses were prepared decennially, seasonally, and by period (dawn, morning, afternoon and evening). The predominant decennial directions were N and SW; they were associated with the regimes of valley/mountain breeze and sea breeze along with the passage of Frontal Systems. The classes of decennial wind were calm (below 1 m.s–1), (40.2%) and light breeze (1 to 3 m.s–1), (39.8%). Seasonally, predominant directions were N, NW, NNE, SSW and SW (autumn); N, NNW, NE, SW and N (winter); N, NNE and SSW (spring); and N, NNW and SW, SSW (summer). By period, predominant directions were N, NW and SSW (dawn); N, NNW and NW (morning); N, NNE and S, SW (afternoon); and S, SW and SSW (evening).
