North Atlantic

Through the inferior circulation, that is sufficiently cool for if dealing with old polar air, he finds yourself loaded of humidity, proceeding from the evaporation of the ocean to the touch of the strong superficial wind. Already the superior rapids if comes across for the opposite, being very hot and dries in value of the strong inversion temperature that it spaces of the superficial one, not assenting that both are agreed, remaining the vapor centered in the superficial chain, with a in such a way higher temperature how much to the minimum the altitude. In accordance with Andrade, on advent of airflows, guarantees. The annual humidity of air and pluviomtricas taxes diminish of the coast for the interior, but, found more to the West the scarp of the Borborema, they increase again due to the orographic rain fall. (ANDRADE, p.39.) When arriving at two chains in its distinguished edges, in doldrum or the coast of Brazil, the thermal discontinuity that if proceeded increasing and cushioning, stops slightly, assenting that if it gives a violent rise of the two layers of the trade wind. The initial, for being almost saturated, cools humid adiabatic gradient according to, while the raised one follows adiabatic the dry one. This event causes to inclination of temperature in altitude and fort inconstncia that cause uninterrupted rains in the coast. This happens especially in the winter, when the trade wind repetidamente is more repetidamente cooled for its combination with maritime polar air, remaining interior the dry one, with the restriction only of the mountain ranges. THE ATMOSPHERIC SECONDARY CIRCULATION OF THE NORTHEAST REGION During the rainy period of the northeast interior (winter), rains do not happen daily: these are discontinued by estiagem occasion, all pendant to the oscillations of the Intertropical Front, that in turn to be subject of the oscillations of the polar fronts of the North Atlantic and South, that act synchronously in identical way and, being enough to us only to present the continental equatorial mass of the last one.
