San Diego, like the remainder of California, was deluged by a number of atmospheric river climate occasions over the 2022-2023 wet season, which each significantly eased the state’s drought and created new varieties of climate hazards.
Because the local weather modifications, so too do methods to foretell and monitor the climate. To that finish, the Scripps Establishment of Oceanography’s Heart for Western Climate and Water Extremes is main the Atmospheric River Reconnaissance program with “Hurricane Hunter” plane from the U.S. Air Pressure Reserve 53rd Climate Reconnaissance Squadron and NOAA.
The joint program goals to gather information on atmospheric rivers, which happen when winds over the Pacific Ocean push moisture-rich heat air towards the West Coast. When it’s pushed upward into cooler air, the ensuing condensation may cause dramatic quantities of rain or snow to fall – on common, 25 occasions the circulate of the mouth of the Mississippi River.
These rivers of moisture can quickly flip round drought circumstances, however additionally they carry with them dangers of utmost flooding, which is simply anticipated to develop into extra pronounced with extra excessive local weather change.
The main points collected with this program will assist put together future local weather fashions, stated Marty Ralph, UC San Diego’s Scripps Establishment of Oceanography meteorologist and founding director of CW3E.
“If you wish to predict the place a automotive goes to be 5 minutes from now you’ll want to know the place it’s ranging from and how briskly it’s shifting,” he stated.
“Equally, if there’s an atmospheric river out close to Hawaii, and we wish to forecast the place it is going to hit the California coast a couple of days later and the way sturdy it’s, we have to get on the market and take direct measurements.”
AR Recon plans to develop additional west throughout the Pacific, operating check flight operations from Guam for a two-week interval this 12 months.
