An explanation from the National Weather Service on atmospheric rivers. 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. [1] [2] Composite satellite photos of an ...
The term "atmospheric river" is a term first used in the 1990s to describe a plume of tropical moisture in the atmosphere that can result in heavy rainfall or snowfall. Use of the term is most ...
Atmospheric rivers could become stronger and have more impacts along the West Coast due to climate change. A new study shows how water rise and increased rainfall could impact residents who face ...
Atmospheric rivers are long and relatively narrow bands of water vapor that form over an ocean and flow through the sky, transporting much of the moisture from the tropics to northern latitudes.
The runoff from the land flows into streams and rivers and discharges into the ocean, which completes the global cycle. [26] The water cycle is a key part of Earth's energy cycle through the evaporative cooling at the surface which provides latent heat to the atmosphere, as atmospheric systems play a primary role in moving heat upward.

An atmospheric river is a wind-borne, deep layer of water vapor with origins in the tropics, extending from the surface to high altitudes, often above 10,000 feet, and concentrated into a relatively narrow band, typically about 400 to 600 kilometres (250 to 370 mi) wide, usually running ahead of a frontal boundary, or merging into it.
Atmospheric Rivers. This headline-making phenomenon has been drenching parts of the West Coast lately — but what, exactly, is an atmospheric river? It occurs when strong winds push tropical ...
In early February 2024, two atmospheric rivers brought extensive flooding, intense winds, and power outages to portions of California.The storms caused record-breaking rainfall totals to be observed in multiple areas, as well as the declaration of states of emergency in multiple counties in Southern California.
