Cyclic tornadogenesis and horizontal vortex tubes in high-resolution idealized simulations of supercells
Ilha de Oliveira, Mauricio (2021-12)Despite enormous progress in our understanding of tornadic supercells obtained over the last several decades, many aspects regarding the evolution of these storms and their attendant tornadoes require further investigation. ... -
Improving High-Resolution Tropical Cyclone Prediction using a Cycled, GSI-Based Hybrid Ensemble-Variational Data Assimilation System for HWRF with Vortex Scale Observations
Lu, Xu (2019-12-13)A Gridpoint Statistical Interpolation analysis system (GSI)-based, continuously cycled, dual-resolution hybrid ensemble-variational (EnVar) data assimilation (DA) system is developed for the Hurricane Weather Research and ... -
Overshooting Convection in the Contiguous United States: Severe Hail Occurrence, Storm Top Characteristics, and Stratospheric Hydration
Murillo, Elisa (2022-12-16)Deep convection that overshoots the tropopause have been recognized for its relevance to stratospheric composition and prolific severe weather production for decades. Notably, tropopause-penetrating storms can inject cloud ... -
Using ground-based fixed and mobile weather radars and numerical modeling to evaluate hurricane structure and dynamics at landfall
Alford, Austin (2021-05-14)Hurricane observations during landfall in the United States have received relatively little attention in the research community compared to hurricanes observed over the open ocean. Aircraft-based observations using in situ ...
