The impacts of higher-temporal resolution radar data on NWS forecasters’ warning decision processes has been explored through the Phased Array Radar Innovative Sensing Experiment (PARISE). To date, PARISE has consisted of three experiments that took place in 2010, 2012, and 2013. In each experiment, NWS forecasters visited Norman, Oklahoma, and worked archived phased array radar (PAR) events in simulated real-time under experimental conditions. The first two experiments focused on forecasters’ warning decision processes during low-end (EF0/EF1) tornado events, and the latter experiment focused on severe hail and wind events. In this seminar, findings from these past experiments will be discussed and summarized. Additionally, we will review how and why PARISE’s experimental design and methodology has evolved over the years by considering our learned lessons from human-related operations research.

The interdisciplinary work of PARISE is continuing to expand. A focus of PARISE’s efforts has been to understand the cognitive aspects of forecasters’ warning decision processes. In the 2012 and 2013 PARISE, cognitive task analysis was employed to address this issue. This method yielded rich, qualitative data from every participating forecaster that proved to be insightful. The present work of PARISE, however, is attempting to take this research further by incorporating cutting-edge eye-tracking technology into our data collection methods through collaboration with human-factors experts. Eye-tracking technology has not been applied to forecaster warning operation scenarios before, but its use in research domains such as military, air traffic control, and medicine gives promise for its utility in meteorology. An eye-tracking pilot study was recently carried out to obtain a first-look at a forecaster’s eye-movements during a simulated warning scenario. We will take a look at the eye-tracking instrument used during this pilot study, and preliminary results will be presented. Lastly, plans for a future 2015 PARISE will be discussed in terms of what research objectives we hope to accomplish and what research questions we will set out to answer.

For accommodations based on disability, or more details, please call 325-6561. All visitors without NOAA or University of Oklahoma identification must register at the registration desk on arrival. Visitor parking is available for all University visitors. However, faculty/staff/students must have a current multi-purpose parking permit. Additional parking is available at the Lloyd Noble Center (LNC) for those individuals who do not have a parking permit. You do not need a permit to park in one of 1,200 spaces reserved for CART bus riders, although you must ride the CART shuttle to park in the reserved area. This area is on the north central side of the Lloyd Noble Center. Elsewhere at the LNC, permits are required.

The University of Oklahoma is a smoke-free / tobacco-free campus.
