Radar characteristics of tornadic and non-tornadic quasi-linear convective systems over the central United States
(University of Missouri--Columbia, 2014)
Tests of quantitative precipitation estimates using national weather service dual-polarization radar in Missouri
(University of Missouri--Columbia, 2015)
Flash flooding is the most common and widespread threat associated with severe weather. Therefore, it is essential for forecasters to be able to properly assess the risk of flash flooding in order to issue watches and ...
Kinetic energy flux associated wiht natural and simulated rainfall events and instrumentation used in the evaluation
(University of Missouri--Columbia, 2011)
There have been many studies that focus on the evaluation of the raindrop-size distribution and the parameters that are based upon this distribution, ranging from radar reflectivity to kinetic energy flux at the surface. ...
Discrimination of elevated convection based on low-level radar-derived convergence
(University of Missouri--Columbia, 2016)
Elevated convection has now been widely associated with severe hazards such as large hail and heavy rainfall, however, high winds and tornadoes are not as common (e.g., Grant 1995, Moore et al. 2003, Horgan et al. 2007). ...
Detection of gust fronts using the doppler velocity derived divergence product
(University of Missouri--Columbia, 2018)
Identifying gust fronts can be essential for situational awareness when developing nowcasts during convective events. In addition to bearing potentially damaging winds, gust fronts also act as forcing mechanisms; influencing ...
An examination of dual-polarized radar nowcasts and their verification using modern shape analysis techniques
(University of Missouri--Columbia, 2016)
Meteorological forecasting on a very short time scale using radar data has always posed numerous problems since the advent of modern radar technology, including what field to use, how strongly to advect the forecast, and ...
Measuring and modeling rainfall with terrestrial sensors and radar : implications for rainfall heterogeneity and discharge
(University of Missouri--Columbia, 2017)
Quantitative precipitation estimates are fundamental for hydrometeorological analyses. Radars provide a superior spatiotemporal advantage over terrestrial-based precipitation gauges to provide such measures of rainfall. ...
Thermodynamic, kinematic, and radar parameters of isolated tornadoes with and without NWS warning
(University of Missouri--Columbia, 2017)
Tornadoes are a rapidly forming weather phenomenon that forecasters may have difficulty anticipating. A tornado warning is issued when atmospheric conditions are imminent for formation or a tornado has already formed and ...
Quantifying evaporation of precipitation below the cloud base using a vertically pointing radar
(University of Missouri--Columbia, 2019)
Evaporation is the transformative process by which liquid water becomes water vapor. This is a very complex process that many times gets parameterized or even omitted in model forecasting. Previous work has been undertaken ...
The use of dispersion modeling to determine the feasibility of vegetative environmental buffers (VEBS) at controlling odor dispersion
(University of Missouri--Columbia, 2012)
Vegetative environmental buffers (VEBs) have been suggested as a possible odor control technology. They have been found to impact odor plume dispersion and have shown the possibility of being an effective tool for odor ...
Ramp event analysis for western Missouri
(University of Missouri--Columbia, 2013)
This work focuses on rapid increases and decreases in wind speed that produce "ramps" which affect wind power calculations and planning. Average wind speeds are predicted with a high level of accuracy; however variable ...
Rainfall observations using dual-polarization radar coupled with a drop motion and evaporation model
(University of Missouri--Columbia, 2013)
Measuring spatial coverage of rainfall is important for several disciplines; unfortunately, rainfall data via rain gauges is very limited in spatial coverage. The best remote sensing tool available for rainfall estimation ...
Infrared and passive microwave satellite rainfall estimate over tropics
(University of Missouri--Columbia, 2005)
Precipitation is an important but highly variable atmospheric parameter. Existing rain gauge networks and weather radar cannot provide the temporal and spatial coverage that is needed to monitor it sufficiently. Thus, ...
Cell identification, verification, and classification using shape analysis techniques
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The use of object-oriented approaches in both the verification of meteorological variables (especially precipitation) and the short-term forecasting ...
An investigation into the contribution of the low-level jet (LLJ) to the available wind resource in Missouri
(University of Missouri--Columbia, 2009)
This work uses data (1 September 2006-31 August 2007) from a network of tall-towers to investigate the impact of the nocturnal low-level jet (LLJ) on near-surface winds in Missouri. Of particular interest is the contribution ...
A tall tower wind investigation of northwest Missouri
(University of Missouri--Columbia, 2007)
With energy needs on the rise and our current energy consumption methods polluting the atmosphere, it is the right time to look at alternative forms of energy production. Six Tall Tower wind observation sites were studied ...
Comparison of rainfall energy and soil erosion parameters from a rainfall simulator and natural rain
(University of Missouri--Columbia, 2007)
Numerous studies have used artificial rainfall to quantify relationships for runoff and soil detachment. Application of these results to natural rainfall conditions is dependent in part on how well artificial rainfall ...
Evaluating and improving the performance of radar to estimate rainfall
(University of Missouri--Columbia, 2008)
A network of 10 rain gages reports data from the Goodwater Creek catchment in central Missouri. Because such a network is expensive to operate, it could be useful instead to use only a few gages and augment the observations ...
A formal evaluation of storm type versus storm motion
(University of Missouri--Columbia, 2008)
In order to predict the location of heavy storm-generated rainfall that could produce flash flooding, forecasters want to know with what velocity a storm will move. However, few systems exist in meteorology where a storm ...
