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 ...
Evaluation of the Warn-on-Forecast System with Doppler Lidar and Mobile Radiosondes from TORUS2019
(2020)
Doppler lidar and mobile radiosonde observations from the Targeted Observations with
Radars and UAS of Supercells 2019 (TORUS2019) eld project are compared to the environ-
mental guidance NSSL Warn-on-Forecast System ...
The Impact of the Madden-Julian Oscillation on Extreme Winter Weather in the United States
(2022-08)
Winter weather has substantial impacts on human activity, but it is challenging to predict more than 7-10 days in advance. Subseasonal-to-seasonal (S2S) prediction is a rapidly developing field of meteorology that could ...
Examining the Vertical Structure of Hurricane Laura (2020) Using Azimuthal-Mean Vertical Profiles and an EOF Analysis
(2023-08-04)
The eyewall, inner rainband, and outer rainband regions of tropical cyclones (TCs) have been extensively studied, resulting in numerous conceptual models. While these conceptual models are insightful regarding basic-state ...
Mesovortex-Induced Tornadoes: A Case Study of the 13 April 2018 Northwest Louisiana Quasi-Linear Convective System
(2022-12-16)
Mesoscale-gamma circulations occurring along the leading edge of Quasi-Linear Convective Systems (QLCS), and their propensity to produce tornadoes and straight-line wind damage has long been noted in literature. Furthermore, ...
Gridded Hail Nowcasting using UNets, Lightning Observations, and the Warn-on-Forecast System
(2023-08-04)
Hailstorms cause around 1 billion dollars in damage across the United States each year. At least a portion of this cost is associated with the inability to protect personal assets from damage in the short window of time ...
GOES-R Stereoscopic Cloud Top Retrieval Algorithm Using Normalized Cross-Correlation for 1-min Overshoot Analysis
(2021-08-05)
Satellite-based cloud top height (CTH) analyses are instrumental in understanding storm dynamics which can be utilized for severe and tornado warnings. Currently, CTHs are derived using IR imagery which are subject to ...
Drop Size Distribution Retrieval from Radar Data to Enhance the Spectral Bin Classification in Detecting Icing Conditions
(2020-07-31)
The emerging Federal Aviation Administration (FAA) restrictions on flight into and out of terminal airspaces (TASs) require discrimination between freezing rain, freezing drizzle, and other forms of winter precipitation ...
Investigating the relationship between aerosol properties and severe weather parameters
(2022-05)
Severe Weather is a common, yet dangerous aspect of weather and climate in the central Great Plains region of the United States. Finding ways to improve the quality of forecasting this phenomenon is important for improving ...
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 ...
