Most research in storm-scale numerical weather prediction has been focused on right-moving supercells as they typically lend themselves to all forms of high-impact weather, including tornadoes. As the dynamics behind splitting updrafts and storm motion have become better understood, differentiating between atmospheric conditions that encourage right- and left-moving supercells has become the subject of increasing…Read more

Looking to the skies -Gail Hartfield, NWA President, August 2017 By the time you read this, our nation will have experienced a once-in-a-lifetime total solar eclipse. The buzz surrounding this event has been astounding. It began well over a year ago when hotels along the path of totality began selling out, and plans for comprehensive…Read more
Low-level thermal ridges (LLTRs) have been identified as common meteorological features associated with wildfires in grass-dominated fuelscapes on the southern Great Plains. Analogous to the well-documented fire-effectiveness of West Coast thermal troughs, LLTRs on the Plains have a dramatic influence on wildland fire. Identification of these features in proximity to midlevel wind maxima has proven…Read more
This study focuses on lightning safety applications at NASA’s Marshall Space Flight Center in preparation for the use of new Geostationary Lightning Mapper data once operational in 2017 from GOES-16. A total of 13 years of North Alabama Lightning Mapping Array and National Lightning Detection data are analyzed for lightning safety applications. Data are analyzed…Read more
