The application of integrated regional enstrophy in identifying the south Asian summer monsoon season
(University of Missouri--Columbia, 2020)
This study uses integrated regional enstrophy (IRE) to identify the onset and termination of South Asian summer monsoon (SASM) (10[degrees] N-25[degrees] N, 80[degrees] E-120[degrees] E) from 2000 to 2019. The SASM region ...
Using soil moisture as a predictor for spring convection within the state of Missouri
(University of Missouri--Columbia, 2020)
Previous studies have shown that increased soil moisture can affect the overlying water vapor in the atmospheric boundary layer (ABL), potentially moistening this layer. Increased buoyancy can create more turbulence and ...
Assessment and diversity of fish communities in non-wadeable tributaries of the Missouri and Mississippi rivers
(University of Missouri--Columbia, 2020)
As the geographical centers of riverscapes, rivers support fish populations at local and basin-wide scales. However, refinements to fish sampling protocols and theories underpinning basin-wide community ecology have been ...
The variability of the El Nino southern oscillation and Modoki mode and their impacts on New York State climate
(University of Missouri--Columbia, 2020)

Phytoplankton response to water quality threats in Midwest reservoirs
(University of Missouri--Columbia, 2021)
Harmful cyanobacterial blooms and invasive species threaten water quality. These threats are expected to worsen in the future, emphasizing the need for creative management solutions and a thorough understanding of their ...
Investigating denitrification from two Missouri claypan soils
(University of Missouri--Columbia, 2020)
Denitrification in agricultural soils is responsible for a majority of anthropogenic nitrous oxide (N2O) production, and N2O is a major greenhouse gas with a global warming potential [approximately] 300 times that of carbon ...
Factors influencing practitioner adoption of agroforestry : a USDA SARE case study
(University of Missouri--Columbia, 2020)
Agroforestry practices offer a compelling alternative to conventional agriculture as they provide a broad range of economic, ecological and social benefits. Despite its' recognized potential, on-the-ground adoption of U.S. ...
