The Atacama Desert can go years without measurable rain

The Atacama Desert can go years without measurable rain

Parts of Chile’s Atacama Desert are so dry that weather stations can record years with no measurable rainfall — among the driest non-polar places on Earth.

Cold ocean currents, stable high pressure, and rain-shadow mountains combine to wring moisture from air before it reaches the gravel plains.

Dryness is an engine, not an empty stage. In the Atacama, dust, salt, and starlight write the landscape where water almost never does.
