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 formation of small-scale atmospheric vortices via horizontal shearing instability
(2014-12-12)
Motivated by recent high-resolution observations of small-scale atmospheric vortices along near-surface boundaries, this study presents a series of simulations that attempt to replicate the dynamics of the dryline and ...
North Atlantic winter surface extratropical cyclone track variability on interannual-to-decadal time-scales.
(2004)
The variability of cyclone activity at interannual and decadal-to-multidecadal time-scales is examined. First, interannual cyclone variability is classified into three major modes based on a VARIMAX Rotated Principal ...
Variational optimization analysis of temperature and moisture advection in a severe storm environment /
(The University of Oklahoma., 1975)
Ensemble Kalman filter assimilation of Doppler radar data for the initialization and prediction of convective storms.
(2006)
Finally, the EnSRF is applied to the May 29-30, 2004 central Oklahoma tornadic thunderstorm case. The initial storm environment is either horizontally homogeneous as defined by a single sounding or is three dimensional as ...
Evaluation of the Warn-on-Forecast System with Doppler Lidar and Mobile Radiosondes from TORUS2019
(2020)
Doppler lidar and mobile radiosonde observations from the Targeted Observations with
Radars and UAS of Supercells 2019 (TORUS2019) eld project are compared to the environ-
mental guidance NSSL Warn-on-Forecast System ...
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 ...
Pulse Compression Waveforms and Applications for Weather Radar
(2015-12-18)
The progression of phased array weather observations, research, and planning over the past decade has led to significant advances in development efforts for future weather radar technologies. However, numerous challenges ...
Closures of the surface energy budget.
(2000)
Results outline appropriate procedures for limiting instrument and system error in measurement of the surface energy budget. A systematic error was identified from an examination of closure at ten OASIS sites, and a ...
