Abstract


Central Depression, is region of great importance for different activities in Rio Grande do Sul. This area is also characterizedfor the high frequency of fog formation, specially in Santa Maria. To identify fog occurrence, METAR message were used.Furthermore, automatic stations data have employed to eliminate fog events under rain conditions in day and day before theevent. The synoptic analysis was done with final data analysis by NCEP. It was observed that in colder months the events aremost frequent. Moreover, the fog occurence is correlated with anticyclone postion in relation to Santa Maria.

Keywords
