Initial error growth in a simulated supercell storm
SPIE Proceedings, 2008In the preceding studies by many authors, in particular they found that moist processes were responsible for the strong initial error growth in meso-scale. In the present study they take a more systematic look at the processes by means of the initial introduced mall errors and found that the errors first grow as small-scale differences associated with ...

The Impact of Hail Size on Simulated Supercell Storms
Journal of the Atmospheric Sciences, 2004Variations in storm microstructure due to updraft strength, liquid water content, and the presence of dry layers, wind shear, and cloud nucleating aerosol concentrations are likely to lead to changes in hail sizes within deep convective storms. The focus of this paper is to determine how the overall dynamics and microphysical structure of deep ...

Analysis of three supercell storms with Doppler weather radar data
Acta Meteorologica Sinica, 2011Three supercell storms on 24 June 2004 (0624), 28 June 2003 (0628), and 27 September 2002 (0927) induced different damages in Shandong Province. Storm 0927 was inferior in size and intensity to storms 0628 and 0624. The structure and evolvement of the three storms were analyzed in detail based on the WSR-98D radar data in combination with weather ...

Simulations of Shallow Supercell Storms in Landfalling Hurricane Environments
Monthly Weather Review, 1996Abstract Numerical simulations of the convective storms that form in tornado-producing landfalling hurricanes show that shallow supercells are possible, even though buoyancy is limited because ambient lapse rates are close to moist adiabatic. Updrafts generally reach peak intensity at low levels, often around 2 km above the surface.

An observational and numerical study of a mini-supercell storm
Atmospheric Research, 1998Abstract The structure and evolution of a small, moderately intense supercell storm, observed over northern Alabama on 17 July 1992, is described through a combined observational analysis and numerical modeling study. Wind profiler measurements show that the storm formed within a favorable low-level wind shear regime confined only to northern Alabama

Radar, lightning, airborne observations and modelling of a supercell storm during EULINOX
Physics and Chemistry of the Earth, Part B: Hydrology, Oceans and Atmosphere, 2000Abstract Detailed observations of a supercell-type storm have been performed on 21 July 1998 in Southern Germany during the field phase of the European Lightning Nitrogen Oxides Project (ELLINOX). An observed cell splitting event and the subsequent intensification of the right-moving storm into a supercell structure was also modelled very well by ...

The Operational Recognition of Supercell Thunderstorm Environments and Storm Structures
Weather and Forecasting, 1994Abstract Supercell thunderstorm forecasting and detection is discussed, in light of the disastrous weather events that often accompany supercells. The emphasis is placed on using a scientific approach to evaluate supercell potential and to recognize their presence rather than the more empirical methodologies (e.g., “rules of thumb”) that have been used

Using Near-Ground Storm Relative Helicity in Supercell Tornado Forecasting
Weather and Forecasting, 2019Abstract This study examines the possibility that supercell tornado forecasts could be improved by utilizing the storm-relative helicity (SRH) in the lowest few hundred meters of the atmosphere (instead of much deeper layers). This hypothesis emerges from a growing body of literature linking the near-ground wind profile to the ...

An Investigation of the Transition from Multicell to Supercell Storms
Journal of Climate and Applied Meteorology, 1986Abstract Nearly 2½ hours of dual-Doppler radar data with high temporal and spatial resolution are used to examine the evolution and morphology of a thunderstorm that evolved from a complex of small cells into a supercell storm. Individual storm cells and updrafts moved east-northeastward, nearly with the mean wind, while the storm complex, which ...

Spatial–temporal characteristics of lightning flash size in a supercell storm
Atmospheric Research, 2017Abstract The flash sizes of a supercell storm, in New Mexico on October 5, 2004, are studied using the observations from the New Mexico Lightning Mapping Array and the Albuquerque, New Mexico, Doppler radar (KABX). First, during the temporal evolution of the supercell, the mean flash size is anti-correlated with the flash rate, following a unary ...
