A new method of calculating vertical motion in isentropic space
(University of Missouri--Columbia, 2014)
A full isentropic vertical motion (?�??) has long been difficult to calculate in an operational forecasting environment. However, recent interactions with the Springfield, MO National Weather Service Office spurred the ...
Management impacts on GHG emissions and yield for an organic soybean cropManagement impacts on GHG emissions and yield for an organic soybean crop
(University of Missouri--Columbia, 2014)
As demand for organically grown food increases, growing organic soybean can be profitable and also improve soil ecosystem services through sustainable agronomic practices. However, because most chemical inputs are restricted ...
Urea fertilizer placement effects on soil greenhouse gas emissions and corn growth
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Agricultural soils are responsible for a majority of human caused greenhouse gas (GHG) production, such as N₂O and carbon dioxide (CO₂). Nitrous oxide ...
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. ...
Management of nitrogen and nitrification inhibitors for corn and wheat production on claypan soils
(University of Missouri--Columbia, 2017)
Use of nitrification inhibitors (NI) in agricultural production systems is considered a risk management strategy for both agricultural and environmental considerations. It can be utilized when risk of reduced nitrogen (N) ...
The relationship between Mid-west precipitation rates, teleconnections and blocking in the Eastern and Central Pacific
(University of Missouri--Columbia, 2016)
An integral aspect of accurate precipitation outlooks are timely forecasts of teleconnective phase transitions (i.e., the El Niño Southern Oscillation (ENSO) and the Pacific Decadal Oscillation (PDO)). Through executing ...
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 ...
Soil physical and hydraulic properties affected by topsoil thickness in switchgrass and row crop management systems /
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Degraded claypan landscapes can be seen as a potential resource for bioenergy production. Therefore, an important decision needs to be made to determine ...
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 ...
Implications for soil health : assessing crop management systems and cover crops on mid-Ohio glaciated soils
(University of Missouri--Columbia, 2016)
Cropping systems management and the presence or absence of cover crops directly influence many physical, chemical, and biological soil properties. The research hypothesis was the use of cover crops and a no-till crop ...
The horizontal redistribution of anomalous vertical heat fluxes at tropical latitudes /
(University of Missouri--Columbia, 2017)
A study was conducted to improve quantitative understanding of how anomalous vertical heat fluxes associated with the El Nio-Southern Oscillation (ENSO) are transported poleward to maintain climate equilibrium. State-of-the-art ...
Imidacloprid sorption and transport in cropland, grass buffer and riparian buffer soils
(University of Missouri--Columbia, 2016)
Knowledge of neonicotinoid sorption and transport in soil is crucial to understanding environmental risk associated with the most widely used class of insecticides. To determine mobility and transport of the neonicotinoid ...
A study of elevated convection and its impacts on surface weather conditions
(University of Missouri--Columbia, 2017)
Elevated convection is a vexing phenomenon that causes forecasting problems for both numerical weather prediction systems and human forecasters alike. It is frequently associated with heavy rain and can produce flash ...
The occurrence of extreme monthly temperatures and precipitation in two global regions
(University of Missouri--Columbia, 2017)
There has been a lot of focus on the occurrence of extreme weather events and their connection to climate change and variability. Much of this previous work has been related to individual events rather than for mean monthly ...
Influence of cover crop and tillage management practices on soil physical and hydraulic properties
(University of Missouri--Columbia, 2017)
Several agricultural land management practices, such as cover crops and tillage, can influence soil physical and hydraulic properties, soil health indicators and crop productivity. This study evaluated the influence of ...
Soil quality in organic cropping systems
(University of Missouri--Columbia, 2016)
The objective of this research was to quantify soil quality indicator levels under contrasting organic practices and to provide scientific information that can lead to development of best management practices for organic ...
Anthropogenic effects on soil physical, chemical, and biological properties in the Missouri Ozarks
(University of Missouri--Columbia, 2018)
The maintenance of healthy forest ecosystems is critical to ensuring the sustainability of forest harvest activities. Forest soil health is a critical component of the knowledge required to manage a forest ecosystem; ...
Influence of residue management on soil chemical properties and nutrient flux in forests harvested for woody biomass
(University of Missouri--Columbia, 2014)
Altered soil solution chemistry and nutrient flux within forests harvested for woody biomass may result from disturbance, slash removals, slash decomposition, and mineralization. Because of the potential adverse effects ...
Assessing soil carbon and soil quality for sustainable agricultural systems in tropical hillslope soils using spectroscopic methods
