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 ...
MOISTURE SOURCES FOR FLASH FLOODS IN THE UNITED STATES
(2017-12)
This dissertation uses backward trajectories derived from North American Regional Reanalysis data for 19,253 flash flood reports published by the National Weather Service to assess the nonlocal contribution of the land ...
Charge Structure and Lightning Patterns in a Simulated Mesoscale Convective System
(2016-05-13)
Observational analyses of electric field measurements and inferred charge structure within the stratiform region of a mesoscale convective system (MCS) repeatedly reveal quasi-steady, horizontal charge layers at and above ...
DOWNSCALING TECHNIQUES FOR RETRIEVAL OF NEAR-SURFACE METEOROLOGICAL FIELDS AND TURBULENCE PARAMETERS FROM ATMOSPHERIC NUMERICAL MODEL OUTPUTS
(2012)
The Weather Research and Forecasting (WRF) model has evolved toward a self- contained numerical weather prediction system, capable of modeling atmospheric mo- tions ranging from global to microscales. The promise of such ...
TOWARDS IMPROVED QPE BY CAPITALIZING GROUND- AND SPACE- BASED PRECIPITATION MEASUREMENTS
(2015-05-08)
There are primarily two types of weather radar systems offering precipitation measurements covering relatively large areas: (1) Ground-based Radar (GR) networks such as the NEXRAD and (2) Spaceborne radars onboard ...
Integrated role of the urban canopy on turbulent transfer with the roughness sub-layer from observations
(2011)
About 50% of the world population nowadays lives in urban areas. With the fast growing trends of urbanization, understanding meteorological processes in such environments is rapidly gaining importance. A complex process ...
