Wind is  considered an important  meteorological variable, but it is not sufficiently studied and there is a shortage of  information on this subject in the region of Santa Catarina. Thus, the objective of this  article was to analyze the behavior of the winds in five regions of the state, with different  aspects: altitude, topography and climatology patterns. For that, daily data from National  Institute of Meteorology of direction and speed of the winds were used from 1974 to  2016. The conventional meteorological stations used were: Chapecó, Campos Novos,  Lages, Indaial and Florianópolis. The data were submitted through consistence analysis,  monthly descriptive statistics of the velocity were obtained, the predominant direction  was characterized through frequency analysis and a conceptual model of prevailing winds  in the state was created. Regarding wind speed, Florianópolis and Campos Novos  registered the highest speeds during the whole year. In the analysis of wind direction,  the prevalence of South Atlantic subtropical anticyclone was observed in most of the year  in Florianópolis (circulation from north), Lages and Campos Novos (from northeast). In  Chapecó, the predominant east wind direction is associated with the low pressure system  in the Paraguay region. For Indaial, the orography has a strong influence on the local  circulation, favoring a southwest wind direction, by the formation of the mountain-valley  breeze, which has as a forcing the air temperature differences between the valley and the  mountain in the night period.  aLocal circulation  aSanta Catarina  aSynoptic circulation  aWind climatology1 aSILVA, F.
