Abstract
Following the events of March 2014 in which icy, hazardous conditions stranded motorists along the roadways and interstate highways of eastern Arkansas, an investigation is launched to determine if the event was the result of cold-air damming occurring in the region. This investigation led to a larger three-phase study on cold-air damming events in the region of the Ozark Plateau. First, the initial phase studies the marquee event of March 2014 and what atmospheric conditions led to the event. Second, a 5-year study to find the frequency and intensity of cold-air damming events in the region. Finally, a numerical analysis using the WRF model to study the effects of terrain height on cold-air damming cases. The objective analysis, results, and conclusions will be showcased including chart analysis, numerical analysis utilizing the Froude number, and WRF output analysis.
