Exploring Tornadogenesis with High-Resolution Simulations Initialized with Real Data
(2012)
Despite large advances in our understanding of tornadogenesis over the past fifty years, a comprehensive dynamical understanding of the processes behind tornado formation remains elusive. The purpose of this dissertation ...
A MOBILE RADAR BASED CLIMATOLOGY OF SUPERCELL TORNADO STRUCTURES AND DYNAMICS
(2010)
Fine-scale-resolution mobile radar observations of supercell tornadoes have been collected by the Doppler On Wheels (DOWs) platform between 1995 and 2010. The result of this ongoing effort is a large observational database ...
OBSERVATIONS OF SUPERCELL TORNADO EVOLUTION USING A MOBILE, RAPID-SCAN, X-BAND RADAR
(2013)
On 24 May 2011, a series of supercell thunderstorms and violent tornadoes tore through central Oklahoma. A mobile, rapid-scan, X-band, polarimetric, Doppler radar (RaXPol), collected data from one of those storms as it ...
On the Limitations of Discriminating Outbreaks of Severe Convection
(2010)
Although much has been learned in recent decades regarding the synoptic and subsynoptic environments associated with major tornado outbreaks, very little research has been conducted using a large sample of outbreak cases ...
Multiple Cyclic Tornado Production Modes in the 5 May 2007 Greensburg, Kansas Supercell Storm
(2011)
Long-track, violent tornadoes are rare events, but are responsible for a disproportionate majority of tornado fatalities, injuries, and property damage. It has been observed that such tornadoes are often generated as part ...
Estimation of Near Surface Tornadic Wind Speeds
(2011)
Modeling studies consistently demonstrate that the most violent winds in a tornadic vortex occur in the lowest tens of meters above the surface. These velocities are unobservable by radar platforms due to line of sight ...
ON THE FURTHER STUDIES OF SUITABLE STORM-SCALE 3DVAR DATA ASSIMILATION FOR THE PREDICTION OF TORNADIC THUNDERSTORMS
(2011)
Storm-scale 3DVAR data assimilation and NWP for the prediction of tornadic supercell thunderstorms still faces many challenges. Some fundamental issues are still not thoroughly (or explicitly) investigated. To name a few: ...
Multiple Cyclic Tornado Production Modes in the 5 May 2007 Greensburg, Kansas Supercell Storm
(2011)
Long-track, violent tornadoes are rare events, but are responsible for a disproportionate majority of tornado fatalities, injuries, and property damage. It has been observed that such tornadoes are often generated as part ...
Mobile, Phased-Array, Doppler Radar Observations of Tornadoes at X Band
(2012)
Previous studies of tornadoes have utilized high-spatial-resolution data obtained by mobile Doppler radars to better understand phenomena that occur on small spatial scales. There has not been a similar focus on using ...
