Abstract
The winds are of fundamental importance in the terrestrial dynamics; Represent one of the main elements influencing various climate phenomena such as soil erosion, pollutant dispersion, seed transport and generation of wind energy. The characterization of the wind at any point of the atmosphere takes two parameters: Speed and direction, which are instantaneous quantities because they depend on conditions such as atmospheric pressure gradient originating displacement of air masses at different temperatures. Accurate information on wind speed is important as it plays a significant role in the application efficiency. Considering the importance of understanding the behavior of the wind, this work, was aimed to characterize the average wind speeds for the city of Teresina, located in the state of Piauí, Brazil. We used 1976 to 2019 data on wind speed of 10 meters height obtained fromthe records of the conventional meteorological station of the National Institute of Meteorology (INMET). The highest wind speed is in July to November with speed ranging from 1.6 to 1.8 m/s and the lowest wind speeds are centered in the months from December to April with oscillation 1.3 to 1.5 m.s-1.
