The Atmospheric Imaging Radar for High Resolution Observations of Severe Weather
(2012)
Mobile weather radars often utilize rapid scan strategies when collecting obser- vations of severe weather. Various techniques have been used to improve volume update times, including the use of agile and multi-beam radars. ...
A MOBILE RADAR BASED CLIMATOLOGY OF SUPERCELL TORNADO STRUCTURES AND DYNAMICS
(2010)
Fine-scale-resolution mobile radar observations of supercell tornadoes have been collected by the Doppler On Wheels (DOWs) platform between 1995 and 2010. The result of this ongoing effort is a large observational database ...
The impact of precipitation physical processes on the polarimetric radar variables
(2012)
The ongoing upgrade of the National Weather Service WSR-88D radar network to polarimetric capabilities, as well as similar upgrades worldwide, will soon provide a wealth of data and information regarding storm precipitation ...
OBSERVATIONS OF SUPERCELL TORNADO EVOLUTION USING A MOBILE, RAPID-SCAN, X-BAND RADAR
(2013)
On 24 May 2011, a series of supercell thunderstorms and violent tornadoes tore through central Oklahoma. A mobile, rapid-scan, X-band, polarimetric, Doppler radar (RaXPol), collected data from one of those storms as it ...
THE APPLICATION OF SPECTRAL ANALYSIS AND ARTIFICIAL INTELLIGENCE METHODS TO WEATHER RADAR
(2010)
Power spectral density (PSD) of reflectivity and polarimetric variables have the potential to provide the linkage between the dynamics and the microphysical properties of scatterers within the radar resolution volume. The ...
KALMAN FILTER BASED TECHNIQUES FOR ASSIMILATION OF RADAR DATA
(2010)
The assimilation of radar data in storm-scale numerical weather prediction models is essential for improved forecasts of thunderstorm events. The huge computational cost of assimilating the high temporal and spatial ...
Applications of Gaussian Mixture Model to Weather Observations
(2011)
The estimation of weather parameters such as attenuation and rainfall rates from weather radar data has been based mainly on deterministic regression models. The applications of a Bayesian approach to weather parameters ...
ASSIMILATION OF ATTENUATED DATA FROM X-BAND NETWORK RADARS USING ENSEMBLE KALMAN FILTER
(2013)
To use reflectivity data from X-band radars for quantitative precipitation estimation and storm-scale data assimilation, the effect of attenuation must be properly accounted for. Traditional approaches try to make correction ...
Applications of Gaussian Mixture Model to Weather Observations
(2011)
The estimation of weather parameters such as attenuation and rainfall rates from weather radar data has been based mainly on deterministic regression models. The applications of a Bayesian approach to weather parameters ...
Mobile, Phased-Array, Doppler Radar Observations of Tornadoes at X Band
(2012)
Previous studies of tornadoes have utilized high-spatial-resolution data obtained by mobile Doppler radars to better understand phenomena that occur on small spatial scales. There has not been a similar focus on using ...
