3 days ago · Atmospheric rivers are narrow bands of water vapor that form in the mid to high latitudes. These can span several miles and carry immense amounts of water – up to 27 times the flow of the Mississippi River. They primarily transport water from tropical oceans toward the poles, causing heavy precipitation during landfall.

Dec 18, 2024 · Atmospheric rivers (ARs) are horizontal plumes of intense water vapour transport in the lower atmosphere that carry water vapour from the warm subtropics to the cooler mid-latitudes and polar...

An atmospheric river (AR) is a narrow corridor or filament of concentrated moisture in the atmosphere. Other names for this phenomenon are tropical plume , tropical connection , moisture plume , water vapor surge , and cloud band .

Filaments of moisture in the atmosphere that transport large amounts of water vapour over long distances have been termed atmospheric rivers, and are often associated with extreme precipitation...

Jan 30, 2025 · NASA’s Earth-observing satellites help scientists identify atmospheric rivers, which enables studies of climate change, water management, and weather. Atmospheric rivers are narrow, elongated corridors of concentrated moisture transport that occur in the lower atmosphere, ahead of the cold front in an extratropical cyclone.
