Recently Chile and Argentina were ranked among the coldest places on Earth outside the polar regions, owing to the polar anticyclone.

Polar Anticyclones

• They are wind systems associated with a region in which high atmospheric pressure develops.
• They are created by the cooling of surface layers of air. 
• This cooling causes the air near the surface to become denser and, which causes an inflow of air at high levels to replace the denser, sinking air.
• These processes increase the mass of air above the surface, thus creating the anticyclone. 
  • Anti-cyclone is a high-pressure area surrounded by low-pressure zones , with winds flowing outward from the center. 
  • Air-movement in anticyclone is outward and clockwise in Northern Hemisphere, outward and anti-clockwise in Southern Hemisphere.
