Improving Drop Size Distribution Retrieval and Rain Estimation from Polarimetric Radar Data using the Deep Neural Network
(2022-08)
Drop size distribution (DSD) and rain rate (R) have been estimated from polarimetric radar data are now available nationwide. DSD and R are essential in understanding rain microphysics. Past studies utilized parametrized ...
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 ...
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 ...
An Evaluation of Radar- and Satellite-Data Based Products to Discriminate Between Tornadic and Non-Tornadic Storms
(2017-12)
Severe weather, and specifically tornadoes, can pose a significant threat to property and human life. Tornadic storms have been extensively studied using radar observations for decades, and some more recent studies have ...
Exploring Tornado Debris Signature Hypotheses Using Radar Simulations and Large-Eddy Simulations
(2021)
Tornadoes can loft various types and sizes of debris, sometimes resulting in a polarimetric radar signature called the TDS (Tornado Debris Signature). The presence of a TDS in the radar data can help confirm the occurrence ...
Quantifying and Mitigating Debris-Induced Bias in Radar Measurements of Tornadic Winds
(2021)
The centrifuging of lofted tornadic debris is known to cause bias in Doppler radar measurements of tornado wind speeds. Debris presence in a radar volume is associated with anomalous radial divergence, underestimation of ...
An Investigation Between Tornadic and Non-Tornadic QLCS Mesovortices using Operational and Experimental MRMS Products
(2023-08-04)
Quasi-linear convective system (QLCS) tornadoes have become an active area of research over the last several years. Through numerical simulations, it is theorized that QLCS vortex formation occurs near the surface in a ...
