In wind energy production through wind turbines, one of the elements that have been stated as much relevant to optimize energy production is the knowledge of the local wind regime in the area in which the wind farm is placed. So, it is very important to be able to characterize the above-stated wind regime to, later, model and simulate it from the short term weather forecasting; this simulation should reproduce the best possible different episodes that characterize the wind regime in the area and verify parametric characteristics that allow defining the wind regime. Wind speed data are analysed to characterize local wind regime (wind speed distribution) and also an analysis of regional and seasonal parameters of local wind regime is done. Also, episodes (gusts) of wind are analysed applying geostatistical techniques (variogram model) and analysis is done characterizing regional and seasonal components. The aim is to analyse wind regime behaviour and show how it can be characterized through variograms that can be classified through typologies, depending on the duration of the episode of wind is short, medium or long.
