Atmospheric Rivers are bands of moisture that come across the Pacific and, on average, carry as much as 25 times the water equivalent of the Mississippi River in the form of vapor. As a result, these systems account for up to half of the West Coast’s annual precipitation, and, subsequently, the flooding. The AR program is led by University of California San Diego’s Center for Western Weather and Water Extremes (CW3E) at Scripps Institution of Oceanography in San Diego who use the data collected by 53rd WRS and the National Oceanic and Atmospheric Administration Aircraft Operations Center’s Hurricane Hunters for forecasting and research purposes. “The purpose of our mission is to get over data sparse areas in the Pacific and collect data forecasters and researchers otherwise wouldn’t have in-depth access to,” said Capt. Garrett Black, 53rd WRS aerial reconnaissance weather officer.

A typical AR recon mission is flown as high as possible in order to get as much of a vertical profile of water vapor in the low level jet over the ocean, which is not detectable by satellite or other conventional observations. Upwards of 25-30 dropsondes are released per flight, gathering atmospheric data such as water vapor, wind, and temperature. “The dropsondes give a three-dimensional look of what’s going on in the atmosphere as far as moisture profiles and where the moisture is located in the atmosphere,” said Black. “That can really tell the forecaster what kind of system we’re looking at as well as giving those forecasting models a great starting point so they can better understand the system’s atmosphere and make more accurate predictions.” 1st Lt.

Col. Tobi Baker, also an ARWO for the 53rd WRS. “The better the forecast, the more local agencies along the coast are aware of how much water they can use from the reservoirs or how much they need to conserve.” While January afforded a handful of data collection missions, the first two months of the new year proved to be dryer than average, sending the Bay Area, a region inhabiting nearly 8 million people, into a nearly 6-week rainless period. During that time, the deployed Airmen made the most of their time flying local sorties for training purposes as well as completing a couple of stepped frequency microwave radiometer calibrations as required prior to the upcoming hurricane season. The squadron will remain staged at Mather through mid-March.
