北大西洋海流
Temperatures are relatively cold for its latitude due to the cold Malvinas Current and the high altitude. For example, in Tierra del Fuego temperatures are colder than at equal latitudes in the northern hemisphere in Europe since they are influenced by the cold Malvinas Current rather than the warm North Atlantic Current. A characteristic of the temperature pattern is the NW–SE distribution of isotherms due to the presence of the Andes.
