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 ...
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 ...
Relationships Between Lidar Aerosol Extinction and Backscatter Coefficients with CCN Number Concentrations in the Southeast Atlantic
(2021-08-05)
Due to seasonal biomass burning and the presence of a semi-permanent stratocumulus deck off the western coast of Africa, the Southeast Atlantic (SEA) region is particularly important in terms of characterizing aerosol and ...
Impact of Microphysics Parameterization Schemes on the Assimilation of GOES-16 All-Sky Infrared Radiances for a Bow Echo Analysis and Prediction
(2023-08-04)
Assimilating infrared brightness temperature (BT) from the water vapor sensitive channels of the GOES-16 Advanced Baseline Imager (ABI) has been shown by past studies to improve the analysis and prediction of severe weather ...
Potential Predictability and Impacts of Subseasonal Extreme Precipitation Events in the United States
(2020-12-18)
Prediction of climate extremes at the S2S time scale has become a large topic of conversation between researchers and decision makers. Long duration precipitation events, lasting 14-days, may lead to devastating impacts ...
Analysis of Tornadic Supercells Using Two Rapid-Scan, Mobile Doppler Radars
(2021-08)
Mobile Doppler radar is a critical tool in studying microscale phenomena, including tornadoes, in supercell thunderstorms at close-range. However, a relative dearth of high-quality cases documenting the tornadic life cycle ...
