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 ...
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.
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 ...
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 ...
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 ...
The term may refer to areas as small as a few square meters or smaller (for example a garden bed, underneath a rock, or a cave) or as large as many square kilometers. Because climate is statistical , which implies spatial and temporal variation of the mean values of the describing parameters , microclimates are identified as statistically ...
