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 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 ...
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 ...
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 ...
Examining Meteorological Benefits of Rapid-Scan, Dual-Polarization, All-Digital Phased Array Radar Observations for Detecting Tornado Formation and Intensification
(2022-08-04)
Phased array radar (PAR) is widely considered the future for a replacement to the current operational radar network, NEXRAD. In particular, an all-digital operational PAR network offers a range of benefits including adaptive ...
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 ...
The Seasonality of Madden-Julian Oscillation (MJO) Teleconnections
(2023-08-04)
The Madden Julian Oscillation (MJO) is a tropical intraseasonal phenomenon that is known to generate teleconnections like the Pacific North American and the North Atlantic Oscillation patterns in boreal winter, but knowledge ...
A Comparative Convective Study Between the Ensemble Kalman Filter and the Local Particle Filter Using the Gridpoint Statistical Interpolation System
(2020-07-30)
The localized particle filter (LPF) is a recent advance in ensemble data assimilation for numerical weather prediction. Derived from the original particle filter used for highly nonlinear state variables, the LPF incorporates ...
Meteorological Benefits of Dual-Polarization, Rapid-Scanning Radar Systems on Hail Producing Storms
(2022-08-04)
Hailstorms continue to be one of the leading economic natural hazards in the United States, amounting to ten billion dollars in damage, on average, annually. Radar tech- nology is one of the best means of detecting hailstorms, ...
