Atmospheric rivers move huge amounts of water through the air above us—and dump rain and snow on land.
In between rainfalls, which occur mainly in the winter, much of California gets very little rain. While this cycle has been the norm, dry spells are getting longer and hotter. When the rains do come, they dump more water in fewer days than they used to. Research indicates that these ...
This can occur in places with cold air, as cold air cannot hold much water vapor. On the other hand, moist air has high humidity levels, often found in warm, humid climates where the air can hold a large amount of water vapor. Cool air also generally holds less water vapor than warm...
Unconfined aquifers have the water table, or the surface where water pressure equals atmospheric pressure, as their upper boundaries. Confined aquifers often lie below unconfined aquifers and have a layer of rock or other materials as their upper boundaries. In the United States, the oldest ground...
Sandbars sometimes peak out above the water, but more often they will be submerged just below the surface. In some cases, the backward pressure of the receding water may be strong enough to break through part of the sandbar. Other times, the water flows along parallel to the beach until ...
Human-induced climate change has amplified atmospheric rivers, which can cause pummeling rain and snow and lead to longer dry periods and wetter days. March 21, 2023 Additional Live Streams Live ABC News Live Live Coldest air in two years for the East, historic winter storm along the Gulf Co...
This paper compares a diverse set of ARDTs by applying them to a single location where a unique 12-year-long time-series from an atmospheric river observatory at Bodega Bay, California is available. The study quantifies the sensitivity of the diagnosed number, duration, and intensity of ARs ...
Past work on how floods cause turbidity currents has often focussed on a model in which the floodwater has enough sediment to become denser than seawater, so that the river-plume plunges to move directly along the seabed as a ‘hyperpycnal flow’27,28,51. This model can be ruled out for...
