The close-up view of the atmopheric river in Oct. 2014 - Mar. 2015.
Atmospheric rivers are short-lived, narrow streams of wind that carry water vapor from the tropical oceans to mid-latitude land areas. Shown here is an atmospheric river traveling across the Pacific between October 1, 2014 and March 31, 2015. (White colors are clouds, light blues water vapor, and green to red precipitation.)
