Atmospheric Circulation

THE ATMOSPHERIC CIRCULATION OF THE NORTHEAST REGION Marcelo Cavalcante Nunes First-born son Graduating Full Licenciatura Geography UEPB. SUMMARY They evidence the arguments in the radiation rocking, coherent with the diversity of the terrestrial surface, that generate disputes of atmospheric pressure, in which conserve the climate in successive circulaes. Either in the normal and secondary circulation atmospheric, preventing of such phenomena caused for the droughts in the northeast Region. As well as for the oscillations that it intends in such way, to finish with the pressure differences, being dislocated the thermal energy them regions of lesser advantage in its circular movements, for the air masses that influences between itself, with the surface of the Region, provoking alterations in the meteorological conditions. Satisfying the Region in what to say respect to the secular environment, analyzing the complexity of the climatic phenomena that if disclose not in great thermal distinctions, but also in the formidable multiplicity of the pluviomtrico, decurrent point of view, basically, of the positioning of this space in affinity to the diverse happened atmospheric systems of circulation in the Northeast Region. Word-Key: Circulation, Pressure, Temperature. INTRODUCTION Climatic, the region northeastern is associated with the high temperatures the year all, with thermal intensities raised around 6 C. But the respective thermal accord it confronts with the ample space variability and the storm of rains.

The coast, the annual precipitation exceeds 1.600mm, while in the interior it does not surpass 400 mm in made right areas. Therefore, the Northeast is evaluated as an irregular region. With abundant years of rains, with disastrous floods that can follow of calamitous estiagens. The origins of such irregularities densely are analyzed, but not yet they have definitive conclusions. However, numerous events gifts in the Region, isolated or combined between itself: As the movements of Hadley-Walker, the Zone of Intertropical Convergence, raised Albedo of the surface, the penetration of Systems Frontals, the irregularities of temperatures of oceanic waters of the Atlantic and the Pacific, the maritime and terrestrial breeze masses equatorial continental, the lines of instability with mass equatorial continental atmospheric of great scale etc.
