A 16-Year Observational Analysis of Land-Atmosphere Coupling in Oklahoma Using Mesonet and North American Regional Reanalysis Data
(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 ...
Examining Extreme Rainfall Forecast and Communication Processes in the South Central United States
(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 ...
Assessing scanning strategies with all-digital phased array weather radars for characterization and detection of microbursts
(2022-05-13)
Microbursts are a rapidly evolving, vertically oriented meteorological phenomena that can be extremely hazardous to aviation, and other human activities, if left undetected. The temporal resolution and vertical sampling ...
A Study Of The Electrical, Microphysical, And Kinematic Properties Of The 29 May 2012 Kingfisher Supercell
(2014)
A supercell thunderstorm formed as part of a cluster of severe storms near Kingfisher, OK on 29 May 2012 during the Deep Convective Clouds & Chemistry (DC3) experiment. This storm produced 5” hail, an EF-1 tornado, and ...
AN ASSESSMENT OF OKLAHOMA WINTER WEATHER THROUGH THE HIGH-RESOLUTION LENS OF UNMANNED AERIAL VEHICLES
(2019-12-13)
Winter weather can lead to power grid failures, disruption of transportation, and can impact the local economy. Specifically in the southern Great Plains, short term model analyses struggle to identify the depth and magnitude ...
Multi-Radar Analysis of the 20 May 2013 Moore, Oklahoma Supercell through Tornadogenesis and Intensification
(2019-12-13)
On 20 May 2013, a violent, long-track EF-5 tornado impacted Moore, Oklahoma and surrounding areas, occurring within a network of radars operating in close proximity to the supercell. This network of radars consisted of ...
Doppler Radar Analyses of Tornadic Supercells on 19 May 2013
(2016-05-13)
On 19 May 2013, two supercells moved through central Oklahoma and produced seven tornadoes, including one of EF-3 and one of EF-4 intensity. High temporal and spatial resolution observations were collected in both strong ...
ANALYSIS OF FLOW AND THERMODYNAMIC CHARACTERISTICS AT A SITE IN COMPLEX TERRAIN
(2018-08)
The goal of the Perdigão Field Experiment was to study atmospheric flows in complex terrain and to collect a high-quality dataset for the validation of meso- and micro-scale models. An Intensive Observation Period (IOP) ...
Non-Terminal Hydrometeor Fall Speed Effects on Modeled Rain Processes
(2023-08-04)
Recent observational studies have shown hydrometeors exhibit non-terminal fall speeds. The goal of this study is to understand how these non-terminal fall speeds affect the collision, coalescence and breakup of raindrops ...
Investigating Arctic Cyclone-Tropopause Polar Vortex Interactions with Observing System Simulation Experiments
(2023-05-12)
Tropopause polar vortices (TPVs) are upper-level cyclonic circulations that are common in high latitudes. TPVs most directly impact weather at the surface by providing baroclinic forcing for the development of Arctic ...
