South America Köppen climate map [24] As part of the Hadley model of atmospheric circulation, the equator is characterised by the ascending branches of separate meridional cells, driven by intense insolation. [25] [26] The vertical convection draws in air from the surrounding atmosphere, known as the trade winds.

Köppen-Geiger climate classification map for South America [35] All of the world's major climate zones are present in South America. [36] The distribution of the average temperatures in the region presents a constant regularity from the 30° of latitude south, when the isotherms tend, more and more, to be confused with the degrees of latitude ...
Global warming was the main driver of the heat wave that scorched South America for most of August and September and raised temperatures by as much as 4.3 degrees Celsius, according to a study ...

The Patagonian Desert is the largest desert south of the 40° parallel and is a large cold winter desert, where the temperature rarely exceeds 12 °C and averages just 3 °C. The region experiences about seven months of winter and five months of summer. Frost is not uncommon in the desert but, due to the very dry condition year round, snow is rare.
Throughout the year, the South Pacific High influences the climate by bringing cold, moist air masses originating from Patagonia. [25] [26] During the most intense cold waves, they form when a transient high pressure system located in the South Pacific Ocean moves eastwards to the southern tip of South America.
