Abstract

Climate presents significant importance on scientific studies due to its influence on life style and even on essential conditions to life. A presentation of climatic theories and the related physical and dynamical processes, underlying the inherent complexity to them, has motivated this revision. In this article, we put in evidence oceanic and climatic oscillation patterns that occur in association to the behavior of the atmosphere. We bring up the importance of heat sources over the Pacific Ocean that are responsible for different patterns (PNA), the South Pacific patterns (PSA), the North Atlantic (NAO) and the Antarctic Oscillation (SAM). The impact on air temperature and precipitation over South America due to the mentioned oscillations is also put in evidence.
