Abstract: Vertical wind shear parameters are presented for 60 left-moving supercells across the United States, 53 of which produced severe hail (≥1.9 cm). Hodographs corresponding to environments of left-moving supercells have a ...

Abstract: AbstractTwo shear-based supercell motion forecast methods are assessed to understand how each method performs under differing environmental conditions for observed right-moving supercells. Accordingly, a 573-case observational ...

Abstract: A case study of a left-moving supercell with a rapid motion is presented to (i) elucidate differences in anvil orientations between left- and right-moving supercells and (ii) highlight the interaction of the left mover ...

Abstract: Observations of supercells and their longevity across the central and eastern United States are examined, with the primary focus on understanding the properties of long-lived supercells (defined as supercells lasting ≥4 ...

Abstract: The evolution of 273 bow echoes that occurred over the United States from 1996 to 2002 was examined, especially with regard to the radar reflectivity characteristics during the prebowing stage. It was found that bow echoes ...
