RWIS based road condition prediction using machine learning algorithms
(2021-06-26)
The need for a forecasting model of road conditions is becoming evermore critical, given the effects of ever-increasing severity in weather. Drastic changes in weather, especially cold fronts, often lead to dangerous roads. ...
Examining Environmental Conditions, Storm-scale Characteristics, and Tornado Potential in Observed and Simulated Supercell Thunderstorms
(2020-07-30)
Despite advancements in our understanding of supercell thunderstorms, numerous questions remain regarding relationships between their environment, storm-scale characteristics, and tornado potential. In particular, quantifying ...
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 Kinematic and Thermodynamic Analysis of the 17 May 2019 McCook / Farnam, Nebraska Tornadic Supercell
(2023-08-04)
The Targeted Observation by Radars and UAS of Supercells field project successfully deployed on a cyclic tornadic supercell in southwest Nebraska on 17–18 May 2019. This case study uses data from the two airborne radars ...
Defining a Relatively Normal Tornado Day: An Exploration of the Climatology and Potential Use of Relative Risk Forecasts for Tornadoes
(2023-08-04)
The risks posed by rare and severe weather events are both the most impactful to the public and the most difficult to communicate, due to their low absolute probability of occurrence but high impact at a given point. Recent ...
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 ...
Machine learning for classifying biological radar echoes with S-band polarimetric radar
(2023-12-15)
The S-band WSR-88D weather radar is sensitive enough to observe biological
scatterers like birds and insects. However, their non-spherical shapes and frequent
collocation in the radar resolution volume create challenges ...
Examining the Predictability of Tornadic and Nontornadic Non-Supercellular MCS Storms using GridRad-Severe Radar Data and Machine Learning Techniques
(2023-12-15)
Many studies have aimed to identify novel storm characteristics that are indicative of current or future severe weather potential using a combination of ground-based radar observations and severe reports. However, this is ...
Subseasonal Variability of Biomass Burning Aerosol Radiative Properties Retrieved by 4STAR during the ORACLES 2016-2018 Campaigns
(2022-05)
Absorbing aerosols play a role in cloud and radiation processes, but these interactions are complex and have a high degree of uncertainty. The interactions of Biomass Burning (BB) aerosols with the semipermanent subtropical ...
