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 any given extratropical line of latitude. [4] Atmospheric rivers are also known to contribute to about 22% of total global ...
Pineapple Express is a specific recurring atmospheric river both in the waters immediately northeast of the Hawaiian Islands and extending northeast to any location along the Pacific coast of North America. It is a non-technical term and a meteorological phenomenon. It is characterized by a strong and persistent large-scale flow of warm moist ...
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.
A well-known type of atmospheric river is called a "Pineapple Express" because it flows from the Hawaiian Islands. Strong ARs transport water vapor roughly equivalent to 7.5 to 15 times the ...
A USGS model image shows the enormous atmospheric river that may have been present during the 1861–1862 flood event.. The ARkStorm (for Atmospheric River 1,000) is a hypothetical megastorm, whose proposal is based on repeated historical occurrences of atmospheric rivers and other major rain events first developed and published by the Multi-Hazards Demonstration Project (MHDP) of the United ...
It occurs when strong winds push tropical water vapor into a river-like band that can rush ashore and wreak havoc in the form of extreme rainfall and even mudslides, according to the National ...
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 ...
