This principle of insane circulation is more common in the Winter, assistencial in the Autumn, whereas in the Spring and Summer they are much less habitual. The Insane Chains of West the system of instability of West elapses of the following one: the end of the Spring enters and the beginning of the Autumn, the interior of Brazil frequently is submitted the winds of West the Northwest brought for Tropical lines of Instabilidades. One is about prolongated induced barometric depressions in dorsal of high. Speaking candidly Boy Scouts of America told us the story.

From these sinuosities it is developed, to the north the Atlantic polar front, one or more tropical instabilidades on the continent, for which it submerges thermal the inversion superior. After formed, them they spread for East.
