The value of point-scale measurements of soil moisture in planetary boundary layer simulations.
(2001)
This study also investigates the sensitivity of ground heat flux estimates at NORM to naturally occurring variability in soil-water content from field samples as well as instrumentation biases associated with the in situ ...
Polarimetric Radar Observations and Numerical Simulations of Tornadic Debris
(2014-05-09)
Tornadic debris are critical aspects of tornado studies because airborne debris pose significant threats to life and property, and debris often dominate backscattered radar signals, causing biased Doppler velocity measurements. ...
HYBRID EN3DVAR RADAR DATA ASSIMILATION AND COMPARISONS WITH 3DVAR AND ENKF WITH OSSES AND A REAL CASE
(2017-12)
Studies have shown advantages of the hybrid ensemble-variational data assimilation (DA) algorithms over pure ensemble or variational algorithms, although such advantages at the convective scale, in the presence of complex ...
Atmospheric Moisture Transport Associated with the West African Monsoon System: An Observational Study and Evaluation of a WRF Dynamical Downscaling Simulation
(2014-05-09)
The intraseasonal variability of the low-level atmospheric moisture transport and its divergence associated with the West African monsoon (WAM) has been investigated for the 1960-2008 period using the NCEP-NCAR reanalysis ...
ASSESSMENT OF ONE-MOMENT AND TWO-MOMENT BULK MICROPHYSICS AND SPECTRAL BIN MICROPHYSICS SCHEMES USING IDEALIZED SUPERCELL SIMULATIONS AND REAL DATA CONVECTIVE-SCALE PREDICTIONS
(2019-05)
Optimal hydrometeor parameterization and their associated processes in microphysics schemes (both spectral bin and bulk) continue to evolve as these schemes attempt to match observed hydrometeor complexity. This dissertation ...
Southeast U.S. Cold Season Severe Thunderstorm Environments and Their Depictions Using Multiple Planetary Boundary Layer Parameterization Schemes
(2015-12-18)
The primary motivations of this dissertation are to identify meteorological characteristics of the southeastern United States cold season tornado environment and to improve numerical modeling of such environments focused ...
A study of hail production in a supercell storm using a Doppler derived wind field and a numerical hail growth model.
(1980)
An investigation is made into the hail production characteristics of a supercell-type storm that occurred in Central Oklahoma on 29 May 1976. The main research tool employed is a three dimensional numerical hail growth ...
Analysis of the Dynamics and Microphysics of a Wet Downburst Case Using Dual-Polarization Radar Data
(2019-05-10)
A significant, wet downburst affected Norman, Oklahoma, on 14 June 2011. Surface winds in excess of 35 m/s (>80 mph) and hailstones in excess of 4 cm diameter occurred during the downburst. The polarimetric S-band (~11.09-cm ...
