The retrieval of initial forecast fields from single Doppler observations of a supercell thunderstorm.
(1998)
Following the velocity blending and adjustment steps, the thermodynamic retrieval is applied to both the single- and dual-Doppler derived wind fields, yielding realistic looking and qualitatively similar perturbation ...
Measurements and modeling of the Great Plains low-level jet.
(2003)
This dissertation describes a project to elucidate the turbulent and momentum structure of the Great Plains Low-Level Jet (LLJ), primarily by the use of Doppler radar. Simple theoretical and numerical models of the LLJ are ...
The impact of radar data assimilation on the Chorwon-Yonchon 1996 heavy rainfall event.
(2003)
One of the most effective tools for observing the atmosphere at fine scales is the Doppler radar. In recent years, considerable research has been directed toward using radar data as a component of numerical prediction model ...
On use of the anelastic vertical vorticity equation in dual-Doppler analyses of the vertical velocity field.
(2001)
The potential for applying the anelastic vertical vorticity equation for dual-Doppler synthesis of the vertical wind field is explored. In particular, application of the vorticity equation as a weak variational constraint ...
3DVAR and cloud analysis with WSR-88D Level-II data for the prediction of tornadic thunderstorms.
(2005)
Doppler weather radar observations play a key role in initializing convective storms within storm-scale numerical weather prediction (NWP) models. The radial velocity and reflectivity are the two main parameters measured ...
Estimation of Doppler and polarimetric variables for weather radars.
(2001)
A method for estimation of Doppler spectrum and its moments as well as several polarimetric variables on pulsed weather radars is presented. This scheme operates on oversampled echoes in range, that is samples of in-phase ...
Variational pseudo multiple-Doppler analyses of a dryline utilizing very-high resolution mobile Doppler radar data.
(2004)
The dryline has long been associated with the development of severe thunderstorms in the southern Plains during the spring and early summer months. The propagation and structure of the dryline are closely tied to surface ...
Spectral analyses of the dual polarization Doppler weather radar data.
(2007)
Echoes in clear air from biological scatterers mixed within the resolution volumes over a large region are presented. These echoes were observed with the polarimetric prototype of the forthcoming WSR-88D weather radar. The ...
A pseudo-dual-Doppler analysis of cyclic tornadogenesis.
(2000)
The goals of this study were twofold. The first was to determine a pseudo-dual-Doppler wind synthesis method in Cartesian coordinates appropriate for the analysis of the ELDORA data. Unique aspects of this part of the study ...
