Forecaster Warning Decision Making with Rapidly-Updating Radar Data
(2017-12)
Phased-array radar is being considered as a potential future replacement technology for the current operational Weather Surveillance Radar 1988 Doppler system. One of the most notable differences in these weather radar ...
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 ...
Observational and model analyses of the Oklahoma City urban heat island
(2014-05-09)
To date, much of the current understanding of the impacts of urban areas on atmospheric processes results from a number of field programs. Between 28 June and 31 July 2003, a vast array of instrument systems collected ...
Near Surface Atmospheric Impacts Resulting From a Developing Metropolitan Area
(2016-12)
Over the past century, the population of the world has become increasingly urbanized. As a result, cities have become larger and more densely populated than any time in history. This unprecedented growth and rapid modification ...
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 ...
Limitations and Potential of Complex Cloud Analysis and Its Improvement for Radar Reflectivity Data Assimilation Using OSSEs.
(2015-12-18)
The radar data assimilation is very important for improving short-range precipitation forecasts. Within the three dimensional variational (3DVAR) framework which is still the prevailing method used for operational regional ...
Coupling Data Science Techniques and Numerical Weather Prediction Models for High-Impact Weather Prediction
(2016-08-12)
Meteorologists have access to more model guidance and observations than ever before, but this additional information does not necessarily lead to better forecasts. New tools are needed to reduce the cognitive load on ...
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 ...
Simulated effects of urban environments on the dynamics of a supercell thunderstorm
(2017-05)
The world's population is increasingly concentrated in large urban areas. Many observational and modeling studies have explored how large, population-dense cities modify local and mesoscale atmospheric phenomena. Urban ...
