Surface Review and Letters, 1999
Efficient calculational techniques for reflection high energy electron diffraction (RHEED) are reported for surfaces with large periodic supercells. A fast Fourier transform approach enables the computer time scaling of a conventional RHEED calculation to be reduced to n2 log (n), where n is the number of diffracted beams used in the calculation.

Supercell Gratings for Light Trapping
Frontiers in Optics 2012/Laser Science XXVIII, 2012Diffractive optics offers interesting opportunities for light trapping in photovoltaics. A supercell grating allows us to tailor the Fourier components of the diffractive structure to the properties of the absorbing material.

Characteristics of Lightning in Supercells
2008This chapter focuses on the lightning and charge structure observed in supercells; a particular class of severe thunderstorms that are typically responsible for producing the most violent hailstorms and tornadoes. The chapter reviews common supercell features, the classification of supercells based on structural and visual characteristics, as well as ...

Influence of orography on supercells in Slovakia
2023<p>The spatial distribution of supercells is strongly inhomogeneous across Slovakia with a higher frequency of occurrence in several regions in the eastern part of the country. The main aim of the work was to find reasons for this inhomogeneity.

Supercell Environments in Finland
Thunderstorms are a common cause of severe weather in the summer season in Finland. Weather phenomena associated with thunderstorms in Finland - such as lightning, torrential rain, wind gusts, significant hail, and even tornadoes – have been associated with extensive economic damage and occasional loss of life.Daan van den Broek +2 more

Variability in supercell motion
Recent studies (e.g., Bunkers 2018, Coniglio and Parker 2020) suggest that tornado-producing supercells often have motion vectors that deviate farther from the mean wind (being slower and more rightward) than non-tornadic supercells. This enhanced deviant motion could be either a cause of tornado production (as such storms would usually experience ...openaire +1 more source
Numerical simulation of a tornadic supercell in the Mediterranean
2016On 28 November 2012, an EF3 tornado developed in southeastern Italy causing one fatality and an estimated damage of 60 MC . At approximately 1050 LT (0950 UTC), this tornado, which initially formed in association with a supercell thunderstorm over the Ionian Sea, moved inland.

Supercells and large hail in Spain
Supercell storms are often associated with severe-weather phenomena such as heavy rainfall, hail, tornados or straight-line winds (downbursts or derechos), all of which can have impactful socio-economic and environmental consequences. Despite these impacts, the lack of data of supercell storms has limited their analysis and characterization of the ...Carlos Calvo-Sancho +4 more
