What are atmospheric rivers?

Atmospheric rivers may sound like a description in a travel blog, but these phenomena cause serious damage. They occur when water evaporates into the air and is carried along by the wind, forming long currents that flow in the sky like rivers flow on land. They can cause severe rains and mountain snow. Atmospheric rivers are partly to blame for the torrential rains in California last week, and another one is expected to hit on Monday.
