Relação da intensidade e direção do vento com a maré meteorológica

The daily life of the population is influenced by several phenomena, one of them, called tide, which consists of the variation in the level of the water bodies that surround the continents. Meteorological tide is defined as the difference between the observed tide and the tideastronomical effects are caused by two causes: variation in atmospheric pressure and exchange of air-sea momentum. During this phenomenon, the water body piles up along the coast, which may exceed its natural limit, reaching occupied and built-up areas causing negative impacts. In this way, the identification of a pattern of association of direction and intensity of winds, associated with events of meteorological tide, helps the decision making of the public power, with regard to coastal management, focused on precaution. This research aimed to determine the values ​​of the meteorological tide and its relationship with the intensity and direction of the incident winds in the period from 2014 to 2019 in the municipality of Itapoa / SC. More intense winds were observed between the months of January to March and in August and September, lower intensities between the months of April to July. The data showed that there is a low positive correlation between the meteorological tide and the meridional and zonal components of the wind, however the most significant is the meridional component. Data analysis and bibliographic review indicate that there is some relationship between atmospheric forcing (wind intensity and direction) and meteorological tide events.
