Impact of increased spatio-temporal radar data resolution on forecaster wind assessments

This study examines the impact of increased spatio-temporal resolution weather radar data on the judgment accuracy and warning decisions of forecasters. In a static part-task setting, weather forecasters were provided with high resolution radar data in addition to conventional radar data and asked to forecast ground level winds two to five minutes into the future. When given these additional data, subjects significantly increased wind speed assessments, decreased absolute error, increased confidence ratings, and changed the number of affirmative warning decisions.
