Using publically available data about wind speed and water vapor flux from real - world atmospheric rivers over the Atlantic, the scientists created a computer model consisting of thousands of moving virtual air particles and found a close match between the complex swirls — the Lagrangian coherent structures — made by the air particles and the patterns made by the real atmospheric rivers.

While atmospheric rivers vary in size and shape, those containing large amounts of water vapor, strong winds, and that stall over watersheds vulnerable to flooding, can create extreme rainfall and floods.

«Given that atmospheric rivers over the Atlantic and Pacific oceans appear as coherent filaments of water vapor lasting for up to a week, and that Lagrangian coherent structures have turned out to explain the formation of other geophysical flows, we wondered whether Lagrangian coherent structures might somehow play a role in the formation of atmospheric rivers,» said study coauthor Vicente Perez - Munuzuri, a physicist at the University of Santiago de Compostela in Spain.

«To date, most methods used to identify atmospheric rivers are based on their water vapor flux or wind speed,» Perez - Munuzuri said.

Yet despite the importance of these «atmospheric rivers» for the global water and heat cycles, the mechanism behind their formation is still a mystery.

A study published this year by Bradley Udall, senior water and climate research scientist with the Colorado Water Institute at Colorado State University, and Jonathan Overpeck, professor of hydrology and atmospheric sciences at the University of Arizona, found that during the drought years of 2000 - 2014, the river surrendered a third of its flow because of higher temperatures in the upper bwater and climate research scientist with the Colorado Water Institute at Colorado State University, and Jonathan Overpeck, professor of hydrology and atmospheric sciences at the University of Arizona, found that during the drought years of 2000 - 2014, the river surrendered a third of its flow because of higher temperatures in the upper bWater Institute at Colorado State University, and Jonathan Overpeck, professor of hydrology and atmospheric sciences at the University of Arizona, found that during the drought years of 2000 - 2014, the river surrendered a third of its flow because of higher temperatures in the upper basin.

They compared two simulations, present and future, of atmospheric rivers determined from the vertically integrated water vapor flux to quantify the changes in atmospheric rivers that make landfall over western North America.

In the hands of the whizzes at SVS, spreadsheets and data turn into a trippy array of bubbles representing gamma rays, or a satellite's view of water vapor swirling into atmospheric rivers.

A NOAA website on atmospheric rivers contains this fascinating statistic that illustrates just how much moisture can be transported by winds in the mid-to-upper atmosphere: «A strong atmospheric river transports an amount of water vapor roughly equivalent to 7.5 - 15 times the average flow of liquid water at the mouth of the Mississippi River.&rriver transports an amount of water vapor roughly equivalent to 7.5 - 15 times the average flow of liquid water at the mouth of the Mississippi River.&rRiver.»

Predictive accuracies ranging from 89.4 % to as high as 99.1 % show that trained deep learning neural networks (DNNs) can identify weather fronts, tropical cyclones, and long narrow air flows that transport water vapor from the tropics called atmospheric rivers.

Higher rates of rain fall there, which is then channeled into valleys, agitates rivers that aren't ready for the gush of water, said Jeff Weber, an atmospheric scientist at the University Corporation of Atmospheric Research, in Boulder, Colo..

Damming of the river has resulted in the build - up of highly methanogenic sediments under a shallow water column, facilitating the transformation of fixed CO2 to atmospheric CH4.

Damming rivers isn't necessarily the only way to extract energy from Earth's water cycle either, though practical large - scale alternatives would require real new technologies like artificial high - altitude reservoirs, or latent heat extractors like the atmospheric vortex ideas.

The atmospheric river storms have arrived in a number and size not seen in years, said Marty Ralph, director of the Center for Western Weather and Water Extremes at the UC San Diego Scripps Institution of Oceanography.

While the ever - important caveat is that it would only take a couple of strong, moist storms (namely, an atmospheric river or two) to bolster our reservoir levels to a level adequate to get us through next summer, there is likely to be rapidly heightening concern in the coming months over possible water shortages in the medium and long term if the «rainy season» doesn't actually become rainy in pretty short order.

From Oct. 1 to March 31, 45 atmospheric river storms made landfall along the West Coast, the Center for Western Weather and Water Extremes reported.

Using variable resolution global models, their analyses will take into account the sensitivity of water cycle processes such as atmospheric rivers and monsoons to model resolution.

The 2012 - 2013 water year was especially remarkable because it began rather early with a series of very intense and moist storms associated with «atmospheric rivers» in Northern California during November but then quickly tapered off, with only light and sporadic precipitation falling for the remainder of the typical «rainy» season from mid-December through May.

The Sun, Jupiter, gravitational moment of the remaining planets, Earth angular orbit variations of all kinds, galactic rays, motion of the solar system through the galaxy and dust clouds, the Moon, atmospheric water vapor, ocean currents, configuration of the tectonic plates and continental drift, volcanic activity, the natural biosphere, human urban development, human alteration of the greenhouse water cycle (dam's, rivers etc),,... human produced CO2.

What that means, he said, is that atmospheric rivers will determine whether California has enough water to survive the climate of the future.

In cold or snow - dominated river basins, atmospheric temperature increases do not only affect freshwater ecosystems via the warming of water (see Chapter 4) but also by causing water - flow alterations.

What is pretty clear, though, is that this year's extreme wetness on the seasonal scale has pushed parts of California's aging water infrastructure to the brink — and had even a single additional warm, wet atmospheric river come ashore during the peak of winter, the overall flood situation might have been considerably more serious.

The storms are being driven by an «atmospheric river,» which, as NOAA explains, is a «relatively narrow» region in the atmosphere «responsible for most of the horizontal transport of water vapor outside of the tropics.»

[26] Historically, the most intense storms and precipitation events in California have been tied to wintertime atmospheric rivers that fed on high levels of water vapor in the air.

On January 3 and 4, the first of two back - to - back atmospheric river storms (wide paths of moisture in the atmosphere composed of condensed water vapor), brought heavy rain and mountain snow to central California, ahead of an even more intense round of heavy precipitation brought by a powerful, long - duration atmospheric river storm pulling warm and moist air to California from the subtropical and equatorial region southeast of Hawaii.

Change in atmospheric patterns pushed Russian river water into Canadian Arctic basin.

The storms, many of which have contained a narrow channel so rich in atmospheric water vapor that meteorologists refer to them as atmospheric rivers, are showing no signs of stopping, either.

-- It seems perfectly reasonable to me that if we imagine the surface never emits that energy in the first place, - energy that is stored in the surface and just below, i.e. oceans, lakes, rivers, ground, and air, — just to mention a few, then any surface temperature change would be completely reliant on variations in Solar irradiation and advection mainly by Water Vapor (WV) but also by other GHGs that have the ability to contain more heat than the rest of the atmospheric gases.

The general cooling and atmospheric circulation changes result in weaker peak river flows and vegetation productivity, which may raise issues of water availability and crop production.
