OSCILLATIONS AND CYCLES OF AIR TEMPERATURE IN SOUTH AMERICA
Abstract
This paper is seeking to prove that on the South American continent there are the same cycles of air temperature (almost perfect) as those proven to exist in Europe (Romania), New Zeeland and North America (the U.S.A.) The oscillations and air temperature cycles of South America have their own characteristics, due to the large expansion of this continent in both latitude and longitude. The absence of important mountain chains with longitudinal display allows quick and intense advection of both Antarctic polar and tropical equatorial air masses. As a consequence, huge amplitudes of the air temperatures appear in some regions. An important role in the evolution of air temperature is played by the ocean currents.
