Análise espaço-temporal dos ventos no extremo norte da Planície Costeira do Rio Grande do Sul, Brasil

The sediment transport between different regions is strongly influenced by wind activity, which can have great influence on the formation of coastal landscapes. Aiming to characterize the wind dynamic in the extreme north of Rio Grande do Sul (RS) Coastal Plain, historic and annual wind data (speed and direction) of four meteorological stations located in the region were analyzed in this study. Results show that in Torres station the winds that occur more often are from NE and S, and winds from W and N are rare. In the SBTR/Airport station, winds from the N-NE quadrant are the most frequent (32%), followed by the winds from SW, SSW and S. In the Central Itapeva Lake station the wind pattern changes slightly, and the most frequent wind directions are NE and SW, with more intense winds coming from SW. It was verified also a variability in the winds directions and frequency during different seasons, with more intense winds during winter. Based on the wind data from each meteorological station, it was found that in the extreme north of RS Coastal Plain the greatest winds intensity (S-SW quadrant) occur at the station which is located further south (Arroio do Sal Municipality), which is closer to the Serra Geral scarps, where the wind direction coincides with the direction free of orographic obstacles. Nevertheless, the spatial-temporal analysis showed that the different localities do not have significant differences in wind directional patterns considering the directional unit as the quadrant.
