Low-Level Polarimetric Radar Signatures in EnKF Analyses and Forecasts of the May 8, 2003 Oklahoma City Tornadic Supercell: Impact of Multimoment Microphysics and Comparisons with Observation
Autor: Daniel T. Dawson II, Louis J. Wicker, Edward R. Mansell, Youngsun Jung, Ming Xue
Publikováno v: Advances in Meteorology, Vol 2013 (2013)
The impact of increasing the number of predicted moments in a multimoment bulk microphysics scheme is investigated using ensemble Kalman filter analyses and forecasts of the May 8, 2003 Oklahoma City tornadic supercell storm and the analyses are vali

Development of New Observation Operators for Assimilating GOES-R Geostationary Lightning Mapper Flash Extent Density Data Using GSI EnKF: Tests with Two Convective Events over the United States
Autor: Rong Kong, Ming Xue, Chengsi Liu, Alexandre O. Fierro, Edward R. Mansell
Publikováno v: Monthly Weather Review. 150:2091-2110
In a prior study, GOES-R Geostationary Lightning Mapper (GLM) flash extent density (FED) data were assimilated using ensemble Kalman filter into a convection-allowing model for a mesoscale convective system (MCS) and a supercell storm. The FED observ

Examining the Kinematic Structures within which Lightning Flashes Are Initiated Using a Cloud-Resolving Model
Autor: Eric C. Bruning, Edward R. Mansell, Vicente Salinas
Publikováno v: Journal of the Atmospheric Sciences. 79:513-530
Lightning is frequently initiated within the convective regions of thunderstorms, and so flash rates tend to follow trends in updraft speed and volume. It has been suggested that lightning production is linked to the turbulent flow generated by updra

Modeling the Electrical Energy Discharged by Lightning Flashes Using Capacitors for Application with Lightning Datasets
Autor: Eric C. Bruning, Edward R. Mansell, Vicente Salinas
Publikováno v: Journal of the Atmospheric Sciences. 78:3909-3924
This study employed a parallel-plate capacitor model by which the electrostatic energy of lightning flashes could be estimated by considering only their physical dimensions and breakdown electric fields in two simulated storms. The capacitor model ha

Lightning Electromagnetics ISBN: 9781849192156
Our goal in this chapter is to introduce the treatments of electrical processes used by numerical cloud models that integrate dynamic, microphysical, thermodynamic and electric processes to track what happens to several classes of water particles as

Impact of Assimilating GOES-R Geostationary Lightning Mapper Flash Extent Density Data on Severe Convection Forecasts in a Warn-on-Forecast System
Autor: Edward R. Mansell, Rong Kong, Brian C. Matilla, Vanna C. Chmielewski, Ming Xue, Yaping Wang, Nusrat Yussouf
Publikováno v: Monthly Weather Review. 149:3217-3241
The Geostationary Operational Environmental Satellite-R (GOES-R) Geostationary Lightning Mapper (GLM) instrument detects total lightning rate at high temporal and spatial resolution over the Americas and adjacent oceanic regions. The GLM observations

Bin-Emulating Hail Melting in Three-Moment Bulk Microphysics
Autor: Edward R. Mansell, Daniel T. Dawson, Jerry M. Straka
Publikováno v: Journal of the Atmospheric Sciences. 77:3361-3385
A three-moment bulk microphysics scheme is modified to treat melting in a size-dependent manner that emulates results from a spectral bin scheme. The three-moment bulk framework allows the distribution shape to change and accommodate some direct effe

Assimilation of GOES-R Geostationary Lightning Mapper Flash Extent Density Data in GSI EnKF for the Analysis and Short-Term Forecast of a Mesoscale Convective System
Autor: Rong Kong, Alexandre O. Fierro, Youngsun Jung, Donald R. MacGorman, Edward R. Mansell, Ming Xue, Chengsi Liu
Publikováno v: Monthly Weather Review. 148:2111-2133
The recently launched Geostationary Operational Environmental Satellite “R-series” (GOES-R) satellites carry the Geostationary Lightning Mapper (GLM) that measures from space the total lightning rate in convective storms at high spatial and tempo
