Abstract

This works aims at the understanding of the mecanism of atuaction of atmospheric systems that generates various types of weather.

A seasonal balance of the participation frequency of those systems in the Santa Maria, RS region is presented. The results were obtained through the analysis of regional circulation.

The year 1973 was chosen, from a larger time segment, as the habitual standard pattern to the central region of the state.

It was made clear that weather control in the region is imposed by Extra-tropical systems. This is due to such system’s major participation in the number of days 334, as opposed the Inter-Tropical System’s 31 days, wich demonstrates the predominance of Cold Fronts and Polar Massas in the atmospheric regional circulation.

Extra-tropical systems have acted with the same intensity in all seasons be it on the shape of the Atlantic Polar Mass or of the Old Polar Mass. The Inter-tropical Systems, however, have acted, almost exclusively, in the pre-front phases and for no longer than two days in a row.
