the regions included in the far North of chile are:,

– XV of Arica y parinacota

– l of Tarapaca

– ll of Atacama

– lll of Antofagasta

The far north (Norte Grande), which extends from the Peruvian border to about 27° south latitude, a line roughly paralleled to the Copiapó River, is extremely arid. It mainly contains the Atacama Desert, one of the driest areas in the world. In certain areas, this desert does not register any rainfall at all. Geographically, the aridity can be explained by the following reasons:

  • The desert is located on the leeward side of the Chilean Coast Range, so little moisture from the Pacific Ocean can reach the desert.
  • The Andes is so high that it blocks convective clouds, which may bring precipitation, formed above the Amazon Basin from entering the desert from the east.
  • An inversion layer is created by the cold Humboldt current and the South Pacific High.
