The Effects of Terrain on an Idealized Tornado using a Large-Eddy Simulation
(2019-08-01)
Tornado structure is known to be sensitive to the characteristics of near-surface inflow, which in turn is affected by inhomogeneities in surface features. Many observational studies such as VORTEX-SE have identified ...
Precipitation Whiplash Events Across the Southern Great Plains of the United States
(2021-08)
The Southern Great Plains is a region that is prone to precipitation extremes and transitions between them which have direct impacts on agriculture, infrastructure, water quality and water quantity. However, current ...
Evaluation of Flash Drought Criteria Components
(2020-12-18)
Flash droughts occur rapidly (approximately 1 month timescale) and have produced significant ecological, agricultural, and socioeconomical impacts. Recent advances in our understanding of flash droughts have resulted in ...
Influences of the Aerosol Invigoration Effect on Radar Signatures of Deep Convection near Houston TX Using a Bulk Statistical Framework
(2023-08-04)
Aerosol-deep convective cloud (DCC) interactions remain a frontier in the study of water cycles, energy budgets, climate models, and air quality, partly because it can be difficult to disentangle aerosol impacts from the ...
Rawinsonde Observations of Supercell-Environment Interactions
(2016-12)
The Mesoscale Predictability Experiment (MPEX) in 2013 and Mini-MPEX in 2016 used mobile soundings to observe the near-storm environments of springtime Great Plains convection. Together, the projects collected over 100 ...
Hailstone Trajectory and Surface Hailfall Analysis in the 29-30 May 2012 Kingfisher, OK Supercell
(2022-05)
During the Deep Convective Clouds and Chemistry Experiment (DC3), a wealth of data was collected on a hail-producing tornadic supercell near Kingfisher, OK on 29-30 May 2012. Three mobile radars collected radial velocity, ...
Examining CERES Downward Shortwave Surface Radiative Flux Measurements in the Context of Oklahoma Mesonet Measurements in 2019-2021
(2023-08-04)
The surface radiation budget affects different components of Earth’s climate system. Accurate assessments of the surface radiation budget help improve climate forecasts, such as drought prediction. In addition, short-term ...
Information content analysis of combined lidar-polarimeter retrievals to improve aerosol remote sensing accuracy
(2021)
Aerosols are small particles suspended in the atmosphere which affect global climate change via scattering and absorbing sunlight and serving as cloud condensation nuclei. Moreover, the prevalence of some anthropogenic and ...
Assessing Precipitation Delineation Capabilities of Spaceborne Radars
(2022-08-04)
Spaceborne radars uniquely measure, provide the finest depiction of, and give the most accurate estimate of precipitation globally from space. The Global Precipitation Measurement (GPM) mission dual-frequency precipitation ...
A Two Part Study in the Evaluation of Quantitative Precipitation Forecasts from Convection-Allowing Models
(2017-12)
Previous studies examining convection-allowing models (CAMs), as well as NOAA/Hazardous Weather Testbed Spring Forecasting Experiments (SFEs) have typically emphasized “day 1” (12-36 h) forecast guidance. These studies ...
