On the Mechanisms of Rain Formation in an Idealized Supercell Storm

Monthly Weather Review, 2015
Abstract Deep convective storms produce raindrops through three mechanisms: condensation and coalescence growth of cloud liquid droplets (i.e., warm processes), melting of ice hydrometeors, and shedding from wet hailstones. To investigate the relative importance of these mechanisms and their contributions to exotic drop size ...

The Impact of Hail Size on Simulated Supercell Storms

Journal of the Atmospheric Sciences, 2004
Variations 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 ...

Influences of CAPE on Hail Production in Simulated Supercell Storms

Journal of the Atmospheric Sciences, 2022
Abstract Lasting updrafts are necessary to produce severe hail; conventional wisdom suggests that extremely large hailstones require updrafts of commensurate strength. Because updraft strength is largely controlled by convective available potential energy (CAPE), one would expect environments with larger CAPE to be conducive to storms producing larger ...

The impact of aerosols and model grid spacing on a supercell storm from Swabian MOSES 2021 [PDF]

Quarterly Journal of the Royal Meteorological Society
The supercell storm that occurred in southwestern Germany on June 23, 2021, had an exceptionally long lifetime of 7.5 hr, travelled a distance of nearly 190 km, and produced large amounts of hail.

Initial error growth in a simulated supercell storm

SPIE Proceedings, 2008
In 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 ...

An Investigation of the Transition from Multicell to Supercell Storms

Journal of Climate and Applied Meteorology, 1986
Abstract 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 ...

The Operational Recognition of Supercell Thunderstorm Environments and Storm Structures

Weather and Forecasting, 1994
Abstract 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

Simulations of Shallow Supercell Storms in Landfalling Hurricane Environments

Monthly Weather Review, 1996
Abstract 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.

Analysis of three supercell storms with Doppler weather radar data

Journal of Meteorological Research, 2011
Three 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 ...
