Observing System Simulation Experiments Using Small Unmanned Aerial Vehicles in Various Configurations to Improve High-Resolution Forecasts of Convection
(2021)
There has been a lot of interest and development of small Unmanned Aerial Vehicles (sUAVs) to
obtain atmospheric measurements for research and operations. Some have proposed a 3D Mesonet
concept to add vertical profiling ...
Synoptic Characteristics and Precursors to Subseasonal to Seasonal Extreme Precipitation Events Across the United States
(2019-08)
In the United States and throughout the world, extreme precipitation events are a major cause of loss in life, property, and economic progress. Although the science of hydrometeorology has made significant improvements 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 Study Of The Electrical, Microphysical, And Kinematic Properties Of The 29 May 2012 Kingfisher Supercell
(2014)
A supercell thunderstorm formed as part of a cluster of severe storms near Kingfisher, OK on 29 May 2012 during the Deep Convective Clouds & Chemistry (DC3) experiment. This storm produced 5” hail, an EF-1 tornado, and ...
Resolution and Physics Sensitivities in Convection-Allowing Models and Ensembles
(2017-08)
In recent years, convection-allowing models (CAMs) and ensembles have become more prominent in both research and operational settings. However, it largely remains unclear how to leverage computing resources to maximize ...
African Easterly Wave Tracks as Simulated by CMIP5 Models
(2017-08)
African Easterly Waves (AEWs) impact Sahel rainfall and serve as trigger disturbances for tropical cyclones (TCs) in the North Atlantic Ocean. So far, there has been very little investigation into future changes in intensity ...
Assessment of stratospheric wave activity associated with the Madden-Julian Oscillation (MJO) and its potential impact on the Quasi-Biennial Oscillation (QBO)
(2021-12)
The Madden-Julian Oscillation (MJO) and Quasi-Biennial Oscillation (QBO) are known to provide sub-seasonal to seasonal predictability, yet their dynamics and interactions are not fully understood. Many recent studies have ...
Colorful Language: Investigating the Interpretation of the Storm Prediction Center's Convective Outlook by Broadcast Meteorologists and the US Public
(2020-07-30)
Though severe weather forecast products, such as the Storm Prediction Center (SPC) convective outlook, have shown to be significantly more accurate than climatology at day-to-week time scales, tornadoes and severe thunderstorms ...
AN ASSESSMENT OF OKLAHOMA WINTER WEATHER THROUGH THE HIGH-RESOLUTION LENS OF UNMANNED AERIAL VEHICLES
(2019-12-13)
Winter weather can lead to power grid failures, disruption of transportation, and can impact the local economy. Specifically in the southern Great Plains, short term model analyses struggle to identify the depth and magnitude ...
Correcting, Improving, and Verifying Automated Guidance in a New Warning Paradigm
(2018-05-11)
The prototype Probabilistic Hazards Information (PHI) system allows forecasters to experimentally issue dynamically evolving severe weather warning and advisory products in a testbed environment, providing hypothetical end ...
