Title Use of Information during the Pacific Land-Falling Jets Experiment
Type Research Project
Abstract The Pacific Landfalling Jets Experiment 2001 (PACJET-2001), a meteorological field experiment to improve wintertime weather forecasts for the West Coast of the U.S., included real-time transmission of the experimental data gathered to National Weather Service (NWS) forecasters. The primary goal of transmitting data in real time, in addition to gathering it for later use in research, was to assist forecasters in predicting coastal and landfalling storms, particularly forecasts of precipitation that might lead to severe flooding. To assess how the data transmitted in real time was and could be used by weather forecasters and users of precipitation forecasts, Rebecca Morss spent four weeks in February-March 2001 observing and interviewing forecasters at NCEP's Hydrometeorological Prediction Center and NWS offices in California, and interviewing California emergency management and water resource personnel. Collaborators include F. Martin Ralph (NOAA ETL) and other members of the PACJET team.

"Because the pathway to sustainability cannot be charted in advance, it will have to be navigated through trial and error and conscious experimentation. The urgent need is to design strategies and institutions that can better integrate incomplete knowledge with experimental action into programs of adaptive management and social learning."
