PRECIP operations were conducted from 25 May to 10 August 2022.
PRECIP
Prediction of Rainfall Extremes Campaign In the Pacific
Overview
Extreme rainfall events cost thousands of lives and billions of dollars in damages every year. However, our understanding of their causes, and our ability to predict them, remain limited. PRECIP will address this need through an in-depth and comprehensive study of the fundamental causes of extreme rainfall events in and around Taiwan, an area that regularly experiences extreme rainfall events during the Meiyu and tropical cyclone seasons.
PRECIP will deploy EOL’s S-Pol research radar along the northwestern coast of Taiwan and Colorado State University’s SEAPOL research radar on Yonaguni, a small Japanese island near Taiwan’s northeastern coast. Field observational data will be collected from radiosondes, dropsondes, and disdrometers deployed across the region, and satellite data collected during the study period will also be utilized. Data will be assimilated and analyzed in conjunction with extensive mesoscale modeling to provide insights into the causes behind extreme rainfall events.
Study Area
Taiwan was selected as the location for PRECIP for four key reasons:
International Collaboration
PRECIP will be coordinated with two other large-scale research projects taking place at the same time in the region: the Taiwan Ministry of Science and Technology Taiwan-area Atmospheric and Hydrological Observation and Prediction Experiment (TAHOPE), and the Japan Grant-in-Aid for Scientific Research Tropical cyclones-Pacific Asian Research Campaign for Improvement of Intensity estimations/forecasts (T-PARCII).
