The Phased Array Radar Innovative Sensing Experiment 2013
The 2013 experiment built on previous methodology and switched the forecasting focus to severe hail and damaging wind events. Twelve NWS forecasters visited the National Weather Center in Norman, Oklahoma to participate in PARISE 2013. This experiment followed an independent measures design. Participants were assigned to a control or experiment group, receiving approximately 4- or 1- min volumetric temporal updates, respectively. All forecasters worked the same three weather cases with the assigned objective of warning on severe weather. Cases were played back in displaced real-time using the AWIPS-2 system, which is a familiar software environment used in all NWS forecast offices. To attain an in-depth understanding of each forecaster's warning decision process, a cognitive task analysis procedure was implemented in the form of a case walk-through. Verification of warnings, assessment of lead time, and a thorough analysis of the warning decision making process is underway. This analysis will provide insight into the extent that higher-temporal resolution data can be effectively used to interrogate severe hail and damaging wind events.
