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 ...
Evolution of Specific Differential Phase in Squall Lines and Corresponding Lightning Channels
(2017-08-01)
Dual-polarimetric radar products have been used in observing changes and persistence of thunderstorm electric fields in relation to lightning discharges. One such product, specific differential phase (KDP), is valuable ...
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 ...
The uncoupled surface layer at the Crosstimber Micronet
(2006)
One of the greatest challenges faced by weather forecasters is the large spatial variability of temperature that occurs at small scales, particularly on clear nights with light wind. The physical processes that create this ...
The "U-Tube": An improved aspirated temperature system for mobile meteorological observations, especially in severe weather
(2012)
The ability to obtain quality air temperature measurements in and around
thunderstorms is often problematic, and even more challenging from a moving platform
such as a ground-based vehicle. Since the original Verification ...
Verification of the Tornado and Lightning Plumes and Evaluation of a New Kernel for the Tornado and Lightning Plumes
(2020-07-30)
Though tornado forecasts have been of interest much longer, the National Weather Service (NWS) has been issuing tornado alerts and warnings for more than 50 years. On 1 October 2007, the NWS began issuing storm-based ...
Observations and Simulations of a Multistatic Weather Radar Network
(2022-05)
Multistatic radar architectures have the potential to provide a cost-effective source of 3D wind information from both operational and research radars, owing to a system design of one transmitter and several receivers. A ...
