USING A LOW-ORDER MODEL TO DETECT AND CHARACTERIZE INTENSE VORTICES IN MULTIPLE-DOPPLER RADAR DATA
(2010)
A new multiple-Doppler radar analysis technique is presented for the objective detection and characterization of intense vortices. The technique consists of fitting radial wind data from two or more radars to a simple ...
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 ...
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 ...
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 ...
A Synoptic and Dynamic Climatology of Heavy Midlatitude Rainfall: Trends Across the United States from 1950-2009
(2010)
The increasing regularity and intensity of heavy precipitation events across the United States during the latter part of the 20th century is widely recognized. Many climate models predict continued growth in the proportion ...
Ensemble Kalman Filter Data Assimilation in the Presence of Large Model Error
(2010)
Though assimilation of synthetically generated surface flux "observations" into numerical forecast models has been attempted, the topic of observed flux data assimilation over land has received little attention. This may ...
APPLICATIONS OF ENSEMBLE KALMAN FILTER DATA ASSIMILATION: FROM CONVECTIVE THUNDERSTORMS TO HURRICANES
(2010)
For the numerical prediction of severe thunderstorm and hurricane, data assimilation is one of the necessary tools to obtain accurate initial conditions. Ensemble Kalman filter (EnKF) is a state of the art data assimilation ...
