Soil quality as affected by agroforestry and grass buffers in grazed pasture and row crop systems
(University of Missouri--Columbia, 2011)
Establishment of agroforestry and grass buffers within agroecosystems is believed to improve soil quality. Soil enzyme activities and water stable aggregates have been identified as sensitive soil quality indicators to ...
The verification of weather forecasts compared to numerical model guidance, climatology, human forecasts and seasonal variations
(University of Missouri--Columbia, 2011)
The accuracy of weather forecasts has been a topic of discussion for many years, and a simple but useful method for showing forecast accuracy has been an issue for meteorologists over time. My study on the comparison of ...
The verification of weather forecasts, numerical modeling, climatology, and variations in enso cycles in forecast accuracy
(University of Missouri--Columbia, 2011)
Weather forecasting has been a difficult problem for meteorologist for more than one hundred years. In the early days, our understanding of atmospheric processes was limited by our incomplete understanding of the governing ...
Sorption and transport of veterinary antibiotics in agroforestry buffer, grass buffer, and cropland soils
(University of Missouri--Columbia, 2011)
Understanding sorption and transport of veterinary antibiotics (VAs) is important for assessing the risk of VAs reaching water resources. Vegetative buffer strips (VBS) may be a useful tool for mitigating veterinary ...
An analysis of northern hemisphere block sizes compared to climatology and seasonal variations
(University of Missouri--Columbia, 2012)
The goal of the following research was to discover if any trends exist between the size of large-scale, mid-latitude anticyclonic events and seasonal characteristics. A 20-year analysis of North American blocking events ...
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 ...
An analysis of the spring-to-summer transition in the west central Missouri Ozarks
(University of Missouri--Columbia, 2014)
The spring-to-summer transition is of special importance in forecasting, as the general circulation undergoes an energy shift to a warmer regime, which affects the Midwestern United States. Beginning at the most localized ...
Soil hydraulic and physical properties as affected by logging management
(University of Missouri--Columbia, 2014)
Former studies have shown that once compacted, forest soils often recover slowly (many decades) to pre-disturbed levels for soil properties such as bulk density or penetrometer resistance. Runoff and soil erosion from ...
Analysis of heavy-rain-producing elevated thunderstorms in the Mo-Ks-Ok region of the United States
(University of Missouri--Columbia, 2014)
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 ...
Environmental implications of phosphate-based amendments in heavy metal contaminated alluvial soil
(University of Missouri--Columbia, 2014)
Soil phosphorus pools and harvest effects on soil solution chemistry in the Missouri Ozark Highlands
(University of Missouri--Columbia, 2013)
Forests ecosystems are governed by complex and dynamic nutrient cycles where soil is a major provider of nutrients essential for plant growth. Disturbances occurring in forested ecosystems (timber harvest, fire, and disease ...
Effects of veterinary antibiotics on atrazine degradation in soil
(University of Missouri--Columbia, 2014)
The release of veterinary antibiotics (VAs) in the environment is concerning because VAs have been linked to the development of antimicrobial resistant bacteria and may influence nutrient cycling and agrochemical degradation. ...
Delineation of critical management areas at plot, field, and watershed scales for claypan soils
(University of Missouri--Columbia, 2010)
Water and soil are two key elements for life on this planet, and improving and preserving their quality are of prime importance. Various human actions including use of intensive chemicals in agriculture have accelerated ...
The climatology of dew points and fire weather related parameters in the Missouri-Arkansas region
(University of Missouri--Columbia, 2010)
Forecasting fire weather in the Springfield, Missouri and Little Rock, Arkansas Weather Forecast Offices (SGF and LZK WFO, respectively) across the greater Missouri and Arkansas regions (MoArk) county warning areas has ...
Alternative tillage and nitrogen management options to increase crop production and reduce nitrous oxide emissions from claypan soils
(University of Missouri--Columbia, 2010)
The Central Claypan Region covers an area of 10 million acres of claypan or claypan-like soil in Missouri, Oklahoma, Kansas, Iowa, and Illinois. Agricultural production on claypan soil can have lower yield and a greater ...
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 ...
A study of the connection between TV meteorologists and their viewers during severe weather broadcasts
(University of Missouri--Columbia, 2013)
After the devastating tornadoes in Joplin, MO and in the Deep South in 2011, it seemed appropriate to look at the impact that broadcast meteorologists (and their TV coverage) have on their viewers during severe weather ...
A study of emergency management policy regarding the use of tornado sirens during severe weather in the state of Missouri
(University of Missouri--Columbia, 2013)
In recent years there have been many devastating tornadoes which have hit cities of all sizes across the state of Missouri, including St. Louis (April 22, 2011) rated EF 4, Joplin (May 22, 2011) rated EF 5 and Sedalia (May ...
