Sentences with phrase «by atmospheric rivers»

Not exact matches

A mighty atmospheric river, fueled by water vapor from the Amazon and heat from the sun, flows across South America until it reaches the Andes and condenses into rain.

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.

The research emerged from a graduate seminar on atmospheric rivers developed by UGA Distinguished Research Professor Tom Mote, one of the authors of the study.

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 basin.

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.»

It's fun to punctuate this atmospheric peace with a trip on a jet boat on the lake or river, and be intoxicated by the speed of the boat.

The resultant severe erosion and potential breach of Oroville Dam's emergency spillway's was then compounded by more atmospheric rivers (Watts 2017a).

After six years of drought, California was deluged in 2017 by sequential «atmospheric rivers» causing the highest January / February rainfall on recent record.

These are largely triggered by storms called «atmospheric rivers.»

Most major floods in California are caused by «atmospheric rivers» from the Pacific Ocean.

A relentless series of storms — driven by persistent troughing and an associated active jet stream along the West Coast — brought numerous atmospheric rivers and associated heavy precipitation to much of the state since November.

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.

The second paper, by Hagos et al. (2016) examines changes to atmospheric river events over western North America, assuming a business - as - usual anthropogenic greenhouse gas emissions.

The spatial extent, intensity and location of atmospheric river (AR) landfall are well reproduced by the RCMs, as is the fraction of winter rainfall from AR days.

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.»

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.

A 2011 report by the US Geological Survey (USGS) found that a single extreme 1000 - year atmospheric river winter storm along the US West Coast could cause up to $ 725 billion in damages to the California economy, much of that from flooding in the Central Valley.

The second storm, fueled by a powerful, long - duration atmospheric river funneling warm and moist air from southeast of Hawaii, hit central and northern California beginning late on January 7 and pushed major rivers past flood stage levels and drove extreme gusts, leading to power outages as well as rock and mudslides.

The emissions and their partitioning only include the fluxes that have changed since 1750, and not the natural CO2 fluxes (e.g., atmospheric CO2 uptake from weathering, outgassing of CO2 from lakes and rivers, and outgassing of CO2 by the ocean from carbon delivered by rivers) between the atmosphere, land and ocean reservoirs that existed before that time and still exist today.

Climate Change Could Alter Them A recent study led by Christine Shields of the National Center for Atmospheric Research suggests that climate change could push atmospheric rivers in the Pacific toward the equator and bring more intense rains to southern California.

The second paper, by Hagos et al. (2016) in Geophysical Research Letters uses output from a global climate model to examine changes to atmospheric river events over western North America, assuming large, business - as - usual anthropogenic greenhouse gas emissions.

-- 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 observed trends may be extrapolated to the coastal seas of the North American Atlantic Ocean and the North, Baltic and Mediterranean Seas, which have received ever - increasing amounts of anthropogenic atmospheric nitrate deposition and river - borne nitrate, comparable to those absorbed by coastal and marginal seas of the northwestern Pacific Ocean.»

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.

We found that Colorado River flows decline by about 4 percent per degree F increase, which is roughly the same amount as the increased atmospheric water vapor holding capacity discussed above.

These warm ocean waters contributed to severe floods over the Ohio River Valley at that time by pumping record levels of atmospheric moisture into the storms running south.
