Climatologia da Região Sul do Brasil : introdução à climatologia dinâmica : subsídios à geografia regional do Brasil

Resumo

In studying the regional climate of South Brazil, the first thing which we observe is referring to its noteworthy, homogeneity, chiefly in respect to its pluviometry and to the stationary rhythm of its regime. The second fact to point out is concerning to its unity. While the other Brazilian regions are characterized by a hot climate of tropical type, the South Region almost exclusively presents a mesothermic climate of temperate type.

This characteristic is due to certain homogeneity and regularity of the factors that act on the weather prevailing conditions.

The Region in question is one of the best provided by rain in the world, considering that the rainfall is uniformly distributed during the year, without any dry month.

Almost all the South of Brazil has a mesothermic climate, with a well pronounced winter and a hot summer, Only in the high areas of the plateau there is a mild summer. In this region the occurrence of hoar-frost and nights with temperatures bellow zero are frequent, mainly on the plateau where, in the years of hard winter, the snow-fall is present, with more frequency in far South of the plateau.
