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 ...
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) ...
The "U-Tube": An improved aspirated temperature system for mobile meteorological observations, especially in severe weather
(2012)
The ability to obtain quality air temperature measurements in and around
thunderstorms is often problematic, and even more challenging from a moving platform
such as a ground-based vehicle. Since the original Verification ...
Synoptic and Mesoscale Analysis of the 2015 Southern Great Plains Flash Pluvial
(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 ...
The Effects of Terrain on an Idealized Tornado using a Large-Eddy Simulation
(2019-08-01)
Tornado structure is known to be sensitive to the characteristics of near-surface inflow, which in turn is affected by inhomogeneities in surface features. Many observational studies such as VORTEX-SE have identified ...
A Comparison of Hybrid-4DEnVar and Hourly Hybrid-3DEnVar Assimilation of Tail Doppler Radar Observations on the Prediction of Rapidly Evolving Hurricanes
(2019-08-01)
Beginning in the summer of 2017 the National Weather Service upgraded the operational Hurricane WRF (HWRF) to a continuously cycled Gridpoint Statistical Interpolation (GSI) based, 6-hourly, Hybrid 3-dimensional (3D) ...
