Supercell Spectrum. Part I: A Review of Research Related to Supercell Precipitation Morphology

open access: yesE-Journal of Severe Storms Meteorology, 2021
This paper reviews the history of nomenclature used to describe the supercell spectrum. Studies are reviewed that attempt to explain the physical processes associated with variations in supercell morphology. The observational evidence for disparate risks associated with variations in morphology is examined.

Many competing ceria (110) oxygen vacancy structures: From small to large supercells [PDF]

open access: yes, 2012
We present periodic "DFT+U" studies of single oxygen vacancies on the CeO2(110) surface using a number of different supercells, finding a range of different local minimum structures for the vacancy and its two accompanying Ce(III) ions.

Wideband/Wide-Angle Planar Single-Layer Retroreflector Using Double Gradient Metasurfaces

open access: yesIEEE Access, 2023
In this paper, a new type of metasurface called Double Gradient Metasurface (DGM) is proposed, which can be used to implement a planar and low-profile retroreflector with a continuous wide incident angle range or a wide frequency width.

Sensitivities of 1-km Forecasts of 24 May 2011 Tornadic Supercells to Microphysics Parameterizations

open access: yes, 2017
On 24 May 2011, Oklahoma experienced an outbreak of tornadoes, including one rated EF5 on the enhanced Fujita (EF) scale and two rated EF4. The extensive observation network in this area makes this an ideal case to examine the impact of using five ...

Comparing Polarimetric Signatures of Proximate Tornadic and Non-tornadic Supercells in Similar Environments [PDF]

open access: yes, 2022
While much research has shown that characteristics of the environment surrounding supercells can potentially indicate their likelihood to become tornadic, it is not uncommon for tornadic and non-tornadic supercells to coexist in seemingly similar ...

Impact of the Streamwise Vorticity Current on Low‐Level Mesocyclone Development in a Simulated Supercell

open access: yesGeophysical Research Letters, 2023
Results from a large eddy simulation of a tornadic supercell developing in a horizontally homogeneous environment are presented which clearly illustrate a connection between low‐level mesoyclone development and the development of a streamwise vorticity ...

Simultaneous Dual-Doppler and Mobile Mesonet Observations of Streamwise Vorticity Currents in Three Supercells

open access: yesMonthly Weather Review, 2020
Recent high-resolution numerical simulations of supercells have identified a feature referred to as the streamwise vorticity current (SVC). Some have presumed the SVC to play a role in tornadogenesis and maintenance, though observations of such a feature

Ab initio calculations of electronic band structure of CdMnS semimagnetic semiconductors

open access: yesДоклады Белорусского государственного университета информатики и радиоэлектроники, 2022
This work is devoted to theoretical investigations of Cd1-xMnxS semimagnetic semiconductors (SMSC). The purpose of this work was to calculate the electronic band structure of ideal and defective Cd1- xMnxS SMSC in both antiferromagnetic (AFM) and ...

Supercell altermagnets

open access: yesPhysical Review B
Altermagnets are compensated magnets with unconventional $d$, $g$, and $i$-wave spin order in reciprocal space. So far the search for new altermagnetic candidates has been focused on materials in which the magnetic unit cell is identical to the non-magnetic one, i.e. magnetic structures with zero propagation vector.
