«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

The
atmospheric river of moisture streaming off of the record warm Pacific ocean is heavily aerosolized (
as described above) which keeps much of the moisture from falling and broadcasts it out into massive regions of rainless (and toxic) cloud cover expanding out over the Western US.

atmospheric rivers» that transport moisture from oceanic hot - spots to drop it on land — but so complex and dynamic
as to be seemingly random and unpredictable.
«All climate models show that
as the climate warms, we should expect more frequent
atmospheric river storms, which isn't good in California because it's almost like too much rain at one time,» she said.
Additionally, many
atmospheric river storms move down the coast over time, so those that made landfall above California frequently moved down to the state
as well.

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
