Caracterização do regime de vento no município de Seropédica, Rio de Janeiro (2001-2010)

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).
