Multi-Radar Analysis of the 20 May 2013 Moore, Oklahoma Supercell through Tornadogenesis and Intensification [PDF]
Atmosphere, 2021 A multi-radar analysis of the 20 May 2013 Moore, Oklahoma, U.S. supercell is presented using three Weather Surveillance Radars 1988 Doppler (WSR-88Ds) and PX-1000, a rapid-scan, polarimetric, X-band radar, with a focus on the period between 1930 and 2008

Polarimetric Radar Characteristics of Tornadogenesis Failure in Supercell Thunderstorms [PDF]
Atmosphere, 2021 Many nontornadic supercell storms have times when they appear to be moving toward tornadogenesis, including the development of a strong low-level vortex, but never end up producing a tornado.

Mesocyclone Evolution and Tornadogenesis: Some Observations [PDF]
Monthly Weather Review, 1978 Abstract Updraft mesocyclones in tornado-producing thunderstorms form along convergent and cyclonically sheared boundaries that separate inflow air entering forward and rear storm quadrants. Maximum tangential flow resides in girding wind bands, averaging usually less than 3 km in radius (depending upon the development stage), that strengthen near ...

Vorticity Evolution Leading to Tornadogenesis and Tornadogenesis Failure in Simulated Supercells [PDF]
Journal of the Atmospheric Sciences, 2013 Abstract A three-dimensional idealized cloud model was used to study the storm-scale differences between simulated supercells that produce tornado-like vortices and those that do not. Each simulation was initialized with a different Rapid Update Cycle, version 2 (RUC-2), sounding that was associated with tornadic and nontornadic ...

Development and Deployment of Air-Launched Drifters from Small UAS [PDF]
Sensors, 2019 Supercell thunderstorms can form extremely dangerous and destructive tornadoes. While high fidelity supercell simulations have increased the understanding of supercell mechanics to help determine how and when tornadoes form, there is a lack of targeted ...

Idealized simulations of aerosol influences on tornadogenesis [PDF]
Geophysical Research Letters, 2008 Numerical simulations of an idealized supercell thunderstorm were performed to assess effects of increased aerosol concentrations acting as cloud condensation nuclei (CCN) and giant CCN (GCCN) on tornadogenesis. Initial background profiles of CCN and GCCN concentrations were set to represent “clean” continental and aerosol‐polluted environments ...

Numerical modeling and analysis of the effect of complex Greek topography on tornadogenesis [PDF]
Natural Hazards and Earth System Sciences, 2014 Tornadoes have been reported in Greece over recent decades in specific sub-geographical areas and have been associated with strong synoptic forcing. While it has been established that meteorological conditions over Greece are affected at various scales ...

Journal of the Atmospheric Sciences, 2021 Abstract Although much is known about the environmental conditions necessary for supercell tornadogenesis, the near-ground vorticity dynamics during the tornadogenesis process itself are still somewhat poorly understood. For instance, seemingly contradicting mechanisms responsible for large near-ground vertical vorticity can be found ...

Supercell Tornadogenesis: Recent Progress in Our State of Understanding [PDF]
Bulletin of the American Meteorological SocietyAbstract Over the last decade, supercell simulations and observations with ever-increasing resolution have provided new insights into the vortex-scale processes of tornado formation. This article incorporates these and other recent findings into the existing three-step model by adding an additional fourth stage.

Delayed Tornadogenesis Within New York State Severe Storms
Journal of Operational Meteorology, 2020 Past observational research into tornadoes in the northeast United States (NEUS) has focused on integrated case studies of storm evolution or common supportive environmental conditions. A repeated theme in the former studies is the influence that the Hudson and Mohawk Valleys in New York State (NYS) may have on conditions supportive of tornado ...
