(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 ...
RADAR POLARIMETRY FOR BIOLOGICAL APPLICATIONS
(2015-05-08)
Radar aeroecology has steadily progressed since its inception in the 1950's, and additional advancements in radar technology, networks, modeling, and validation continue to drive the science further. As human impacts ...
ASSIMILATION OF RADAR OBSERVATIONS WITH ENSEMBLE VARIATIONAL HYBRID DATA ASSIMILATION METHOD FOR THE INITIALIZATION AND PREDICTION OF HURRICANES
(2015-05-08)
Data assimilation is a critical component for accurate model forecast. This dissertation investigated the ensemble-variational hybrid data assimilation methods using land based radar and airborne radar data for the prediction ...
Nocturnal Boundary Layer and Low-level Jet Characteristics under Different Turbulent Regimes
(2015-05-08)
The intensity, extent, and continuity of turbulence in the nocturnal stable boundary layer (SBL) is governed by many interacting processes and features. Generally, SBLs can be grouped into two broad categories: weakly ...
Limitations and Potential of Complex Cloud Analysis and Its Improvement for Radar Reflectivity Data Assimilation Using OSSEs.
(2015-12-18)
The radar data assimilation is very important for improving short-range precipitation forecasts. Within the three dimensional variational (3DVAR) framework which is still the prevailing method used for operational regional ...
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 ...
TOWARDS IMPROVED QPE BY CAPITALIZING GROUND- AND SPACE- BASED PRECIPITATION MEASUREMENTS
(2015-05-08)
There are primarily two types of weather radar systems offering precipitation measurements covering relatively large areas: (1) Ground-based Radar (GR) networks such as the NEXRAD and (2) Spaceborne radars onboard ...
Optimizing Lidar Scanning Strategies for Wind Energy Turbulence Measurements
(2015-05-08)
Turbulence has a significant effect on wind farm power production and turbine reliability. Since remote sensing devices, such as lidars, are commonly used in wind energy studies, the accurate measurement of turbulence with ...
Relationships between Monthly Agroclimate Variability and Local Crop Yield in the Central and Eastern United States and Southern Canada
(2015-05-08)
Short-term agroclimate is defined here as the monthly-to-seasonal meteorological, geological, biological, and psychological factors that modulate local and regional crop yield. Modern agricultural production in the central ...
