The state of Santa Catarina presents significant spatial variations in its 
climate, with different regional peculiarities. 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.
