atmospheric river meaning
ENWAtmospheric river
- An atmospheric river is a narrow corridor or filament of concentrated moisture in the atmosphere.
- The term was originally coined by researchers Reginald Newell and Young Zhu of the Massachusetts Institute of Technology in the early 1990s, to reflect the narrowness of the moisture plumes involved.
- Atmospheric rivers have a central role in the global water cycle. On any given day, atmospheric rivers account for over 90% of the global meridional (north-south) water vapor transport, yet they cover less than 10% of the Earth's circumference.
