Forecaster Warning Decision Making with Rapidly-Updating Radar Data
(2017-12)
Phased-array radar is being considered as a potential future replacement technology for the current operational Weather Surveillance Radar 1988 Doppler system. One of the most notable differences in these weather radar ...
Observational and model analyses of the Oklahoma City urban heat island
(2014-05-09)
To date, much of the current understanding of the impacts of urban areas on atmospheric processes results from a number of field programs. Between 28 June and 31 July 2003, a vast array of instrument systems collected ...
Near Surface Atmospheric Impacts Resulting From a Developing Metropolitan Area
(2016-12)
Over the past century, the population of the world has become increasingly urbanized. As a result, cities have become larger and more densely populated than any time in history. This unprecedented growth and rapid modification ...
Limitations and Potential of Complex Cloud Analysis and Its Improvement for Radar Reflectivity Data Assimilation Using OSSEs.
(2015-12-18)
The radar data assimilation is very important for improving short-range precipitation forecasts. Within the three dimensional variational (3DVAR) framework which is still the prevailing method used for operational regional ...
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 ...
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 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 ...
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 ...
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 ...
A HIGH RESOLUTION DISTRIBUTED HYDROLOGIC MODEL CLIMATOLOGY OVER THE CONTERMINOUS UNITED STATES FOCUSED ON FLASH FLOODING
(2016-08-12)
This study will describe the MRMS reanalysis precipitation dataset created for the time period from 2001 to 2011. This high resolution 1-km^2 5-minute dataset is ideal for simulating flash floods with a distributed hydrologic ...
