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.
The same amount of water falls as atmospheric precipitation, 458,000 km 3 on the ocean and 119,000 km 3 on land. The difference between precipitation and evaporation from the land surface (119,000 − 74,200 = 44,800 km 3 /year) represents the total runoff of the Earth's rivers (42,700 km 3 /year) and direct groundwater runoff to the ocean ...
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 ...
The runoff from the land flows into streams and rivers and discharges into the ocean, which completes the global cycle. [5] 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.
