Abstract

Determining the wind fields associated with sea breezes is essential for assessing oceanic-atmospheric processes in coastal areas, such as the transport of pollutants and the generation of wind-sea waves. With this information, it is possible to quantify the produced effects from the continent in the sea and understand the coastal erosion processes during the day. It is important to emphasize that in the coastal part of the Gulf of Urabá, there is frequent disposal of pesticides spread from small planes and that the east coast of the gulf presents accelerated coastal erosion processes. In the present work, the characterization of the diurnal cycle of sea breezes on the coasts of the Gulf of Urabá was carried out using the results of the Weather Research and Forecasting (WRF) model. To this purpose, wind and temperature fields were analyzed for January and February from 2008 to 2013. Wind values at various levels of the vertical and surface wind fields were compared with in situ information. It was found that the breeze system begins its movement from sea to land between 07:00 and 10:00 local time (LT) and reverses between 13:00 and 16:00LT. Evidence of the change of direction is the surface temperature values which were positively correlated with the wind. As future work, the WRF model is expected to be implemented for recent years to carry out an adequate calibration/validation process using climatic stations that have been installed lately.
