A 16-Year Observational Analysis of Land-Atmosphere Coupling in Oklahoma Using Mesonet and North American Regional Reanalysis Data
Wakefield, Ryann (2018-08)Global “hot spots” for land atmosphere coupling have been identified through various studies. One particular region that has been identified in many of these global studies is the Southern Great Plains (SGP) of North ... -
Abrupt Agricultural Flash Drought: An Investigation of Rapid Drought Development Across Vital Agricultural Zones of the United States
Fellman, Benjamin (2023-05-12)Flash droughts are highly impactful, subseasonal to seasonal events that pose a severe risk to agricultural production. The 2012 flash drought event in the United States is a prime example, as this event resulted in tens ... -
Assessing Precipitation Delineation Capabilities of Spaceborne Radars
Searls, Maresa (2022-08-04)Spaceborne radars uniquely measure, provide the finest depiction of, and give the most accurate estimate of precipitation globally from space. The Global Precipitation Measurement (GPM) mission dual-frequency precipitation ... -
Correcting, Improving, and Verifying Automated Guidance in a New Warning Paradigm
Harrison, David (2018-05-11)The prototype Probabilistic Hazards Information (PHI) system allows forecasters to experimentally issue dynamically evolving severe weather warning and advisory products in a testbed environment, providing hypothetical end ... -
Evaluating the Effects of Vegetation Cover and Phenology on the Components of the Surface Energy Fluxes, Soil Temperature and its Damping Depth, Soil Moisture and the Partitioning of the Evapotranspiration Across Forest, Grassland and Desert Ecosystems
Pham, Tri (2020)The understanding and modeling of the effects of land-cover change on the behaviors of evapotranspiration flux and its partitioning, soil moisture, soil temperature, and surface energy fluxes which include ground heat flux, ... -
Evaluation of Flash Drought Criteria Components
Edris, Stuart (2020-12-18)Flash droughts occur rapidly (approximately 1 month timescale) and have produced significant ecological, agricultural, and socioeconomical impacts. Recent advances in our understanding of flash droughts have resulted in ... -
Examining Extreme Rainfall Forecast and Communication Processes in the South Central United States
Wanless, Anna (2021-08)Extreme rainfall events have increased in parts of the United States and climate models project that trend to continue (Carter et al. 2018; Mullens et al. 2013; Hayhoe et al. 2018). As such, forecasters must be able to ... -
The Impact of the Madden-Julian Oscillation on Extreme Winter Weather in the United States
Foskey, Stephen (2022-08)Winter weather has substantial impacts on human activity, but it is challenging to predict more than 7-10 days in advance. Subseasonal-to-seasonal (S2S) prediction is a rapidly developing field of meteorology that could ... -
In-Situ Measurements and Remotely Sensed Estimations of Surface Fluxes over the Southern Great Plains of the United States
Mahan, Hayden (2016-12)Evapotranspiration (ET) is an important variable in the hydrologic cycle. As such, improved understanding of the spatial and temporal variability of ET is critical to weather and climate analysis and prediction, water ... -
A Multidimensional Analysis of an Anomalous, High-Impact, Early-Season Ice Storm in Oklahoma
Woodward, Alyssa (2022-08)Between 26 to 28 October 2020, an anomalous, high-impact, and early-season ice storm affected much of Oklahoma. This was the first time the National Weather Service (NWS) Forecast Offices in both Norman and Tulsa had issued ... -
Quantifying Precipitation Efficiency and Drivers of Excessive Precipitation in Post-Landfall Hurricane Harvey
Brauer, Noah (2019)Hurricane Harvey produced widespread rainfall amounts over 1000 mm in portions of Southeast Texas, including Houston from 26-31 August 2017. The highly efficient and prolonged warm rain processes associated with Harvey ... -
Radar analysis of the physics of extreme rainfall events
Bunker, Ryan (2020)Extreme precipitation events pose a threat to life, property, and economic growth throughout the United States and across the world. Although extensive research has focused on improving understanding of extreme precipitation ... -
SEVERE HAIL DETECTION USING REMOTE SENSING OBSERVATIONS AND AN EVALUATION OF THE ABOVE ANVIL CIRRUS PLUME FOR SEVERE WEATHER DETECTION
Murillo, Elisa M. (2018-12-14)This thesis undergoes a comprehensive comparative analysis to address two main objectives: a) Thoroughly assess available radar, satellite, and lightning based products’ ability to identify hail events and size, and b) ... -
Synoptic and Mesoscale Analysis of the 2015 Southern Great Plains Flash Pluvial
Wugofski, Sarah (2019-08)During May and June of 2015, the Southern Great Plains (SGP) of the United States experienced numerous heavy rainfall and flooding events. The immense amount of rainfall (in excess of 80 cm) over a short period had tremendous ... -
Synoptic Characteristics and Precursors to Subseasonal to Seasonal Extreme Precipitation Events Across the United States
Jennrich, Gregory (2019-08)In the United States and throughout the world, extreme precipitation events are a major cause of loss in life, property, and economic progress. Although the science of hydrometeorology has made significant improvements to ...
