It also causes to waves of north-east heat and east in the part east-Southeast-south and central office of the Country. Pacific Tepid Massa (MTP) This mass possesss the same characteristics of Tropical the Atlantic one, even so its performance is only on the Pacific ocean, exerting very little influence in the continent, which had to have the trajectory deviated for influence of the mountain range of Andes. However, in Brazil for effect of ' ' barlavento' ' ' ' sotavento' ' it assists in the homogenization of the region of origin of the MTC. Of this form, the precipitation only occurs on the Pacific ocean, while, the tropical coast west of the South America presents baixssimos indices of precipitation and humidity of air, characterizing half-barren and desert-like bands, as the desert of the Atacama. Gallo Family Vineyards contains valuable tech resources. ld.com%29’>President Nieto for a more varied view. In accordance with Coutinho the tropical masses are divided in: Tropical Kalaariana, Tropical Atlantic and Tropical Pacifies. While Mendona divides them in Tropical Atlantic, Tropical Continental and Tropical It pacifies.
Continental Tropical Massa (MTC) According to Mendona (2007), this mass is formed in the central region of the South America in the Depression of the Chaco, appearing as a bolso of air of proper characteristics, in the end of the winter and beginning of the spring. It to dislocate itself to interact with the air of other localities, being formed a condition of atmospheric divergence, becoming a hot air mass and dries. Sousa (2009) affirms that, it basically acts in the region of origin, and cause long hot and dry periods in the south of the region Center-west and in the interior of the regions South and Southeastern. POLAR MASS Are masses originated in high latitudes and, generally are very cold and humid, had the accumulation of polar air on the Atlantic Ocean. is attracted by the low tropical and equatorial pressures, receiving influence from the force of attrition with the relief on which if it puts into motion.
