UC San Diego will send airborne scientists into huge offshore storms to deepen their understanding of ”atmospheric rivers,” the plumes of moisture that can bring nourishing rains, and flooding, to the West Coast.

The second of up to 12 winter weather reconnaissance flights is scheduled to take off from Travis Air Force Base near Sacramento on Tuesday, carrying researchers from NOAA and the Air Force. UCSD will add its own researchers to the trips in about a week.

The university is partnering with the government and military on the project, which is being run out of the UCSD’s Scripps Institution of Oceanography.
