Pulse Compression Waveforms and Applications for Weather Radar
(2015-12-18)
The progression of phased array weather observations, research, and planning over the past decade has led to significant advances in development efforts for future weather radar technologies. However, numerous challenges ...
On the Limitations of Discriminating Outbreaks of Severe Convection
(2010)
Although much has been learned in recent decades regarding the synoptic and subsynoptic environments associated with major tornado outbreaks, very little research has been conducted using a large sample of outbreak cases ...
Coupling Data Science Techniques and Numerical Weather Prediction Models for High-Impact Weather Prediction
(2016-08-12)
Meteorologists have access to more model guidance and observations than ever before, but this additional information does not necessarily lead to better forecasts. New tools are needed to reduce the cognitive load on ...
Multiple Cyclic Tornado Production Modes in the 5 May 2007 Greensburg, Kansas Supercell Storm
(2011)
Long-track, violent tornadoes are rare events, but are responsible for a disproportionate majority of tornado fatalities, injuries, and property damage. It has been observed that such tornadoes are often generated as part ...
EVOLUTION OF CHARGE AND LIGHTNING THROUGHOUT AN OBSERVED AND SIMULATED SUPERCELL STORM
(2010)
A high-precipitation tornadic supercell storm was observed by multiple platforms on 29 May 2004 during the Thunderstorm Electrification and Lightning Experiment (TELEX). Observational systems included the Oklahoma Lightning ...
Simulated effects of urban environments on the dynamics of a supercell thunderstorm
(2017-05)
The world's population is increasingly concentrated in large urban areas. Many observational and modeling studies have explored how large, population-dense cities modify local and mesoscale atmospheric phenomena. Urban ...
A Phenomenological Investigation of Voluntary Exits from the Atmospheric Science Occupation
(2017-05)
Data available from several atmospheric science (including meteorology) degree programs suggest that a sizable number of degree-holding atmospheric scientists may work outside of the atmospheric science occupation. In cases ...
A BALLOON-BORNE PARTICLE SIZE, IMAGING, AND VELOCITY PROBE FOR IN SITU MICROPHYSICAL MEASUREMENTS
(2016-12-16)
A balloon-borne instrument known as the PArticle Size, Image, and Velocity (PASIV) probe has been developed at the National Severe Storms Laboratory to provide in situ microphysical measurements in storms. These observations ...
QUANTIFYING UNCERTAINTIES IN GLOBAL AND NORTH AMERICAN REGIONAL CLIMATE CHANGE PROJECTIONS USING A MULTI-THOUSAND MEMBER GLOBAL CLIMATE MODEL PERTURBED PHYSICS ENSEMBLE
(2013-11)
Information on the uncertainties in projections of future climate change from global climate models (GCMs) is vital for their effective use across a wide range of applications, including their increasing role in driving ...
Estimating and Mitigating Errors in Dual-Polarization Radar Attenuation Correction
(2014-12-12)
Correction for rain attenuation is an important data quality issue when using data collected by radars operating at attenuating wavelengths, specifically C and X bands. Such issues are especially important for quantitative ...
