“…In Pelotas, city located in the extreme south of Brazil, Silva et al (1997) found a high frequency of southwest wind in the months of fall and winter. In southern latitudes, in La Plata, Argentina, where the migratory anticyclone incursions is higher (PEZZA, 2003), the wind frequency of southwest/south/southeast is so elevated as the frequency of northeast/north winds (RATTO and NICO, 2012).…”

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.RESUMO: Apesar do estado de Santa Catarina possuir pouca variação na latitude, apresenta variações espaciais significativas no seu clima, como verificado neste estudo. O vento é considerado uma importante variável meteorológica, porém não é suficientemente estudado e existe uma escassez de informações sobre esse assunto na região de Santa Catarina. Sendo assim, o objetivo deste artigo foi analisar o comportamento dos ventos em regiões do estado, com diferentes aspectos: altitude, topografia e padrões climáticos. Para tanto, foram utilizados dados diários no Instituto Nacional de Meteorologia (INMET) da direção e velocidade dos ventos no período de 1974 a 2016. As estações meteorológicas convencionais utilizadas foram: Chapecó, Campos Novos, Lages, Indaial e Florianópolis. Após consistidos, os dados diários de vento foram _________________Revista Brasileira de Climatologia_________________
