The Prediction of Rainfall Extremes Campaign in the Pacific, or PRECIP, field campaign was conducted over a period of nearly three months this summer in Taiwan and southern Japan to improve understanding of when, why and how the atmosphere produces extreme rainfall.

James H. Ruppert, Jr., Ph.D., an assistant professor in the School of Meteorology, College of Atmospheric and Geographic Sciences, became involved with the campaign through his research in improving understanding of tropical heavy rainfall. Through funding from the National Science Foundation, he and two School of Meteorology masters’ students in his Convective Storm Dynamics research group, Theresa Lincheck and Emily Luschen, traveled to Taiwan and Japan to support data collection for the PRECIP project.

“This region was specifically targeted because extreme rainfall events have a special flare here in summertime, where typhoons, afternoon downpours, and the southwesterly monsoon – the ‘Mei-yu’ – may bring deluge on any given day,” Ruppert said.

The field campaign collected detailed observations using a suite of radars and sounding systems in collaboration with multiple U.S. universities, Taiwan, and Japan. PRECIP was led by Colorado State University. The campaign began on May 25 and concluded on Aug. 10, 2022.
