Résumé:
The present study had its ability to identify the Atlantic Ocean waters (SST) in the tropical Atlantic in the years 1985, 2009 and 2011. The Asian year was considered as rules of the austral summer (January to March) and austral autumn (March to May) when the rainy season begins in the North Northeast of Brazil due to the Intertropical Convergence Zone (ZCIT). Compared tests are from an analysis made up of reanalysis data that comprises 36 years, being subjected to a climatology and anomaly field for SST, wind, rain, heat flow, sensitive and radiative, pressure at the mean sea level and field of convergence at high and high levels. These fields gave the possibility to analyze the cause and effect generated as SST anomalies that are driven by changes in the wind, the actions in the countries and the oceanic components. As the analyzed variables could show that in 1985 there was a period of SST anomalies positive over the Northeast, there was a prolonged period until the month of May. The ITCZ will move up to 5N, and extend its period of stay until the month of May. Oceanic factors such as resurgence and mixing layer were the factors that caused the cooling on the North Atlantic, which caused the disease to remain in the South Atlantic underworld. The year 2009 was a year of positive anomalies over the North Atlantic Ocean and had as its cause and effect the oceanic and atmospheric phenomena interacting and causing the non-Atlantic north cooling and causing the ITCZ to move further into the Southern Hemisphere. year of 2011 had as positive characteristics the North Atlantic Ocean, which caused several factors like the anomalous weakening of ASAS, oceanic phenomena such as the current of the Canaries, resurgence, anomaly in the Walker cell among others, which caused the rains Losing until the day of July in the Brazilian Northeast.
