Insights into Supercells and Their Environments from Three Decades of Targeted Radiosonde Observations

, 2020
Hundreds of supercell proximity soundings obtained for field programs over the central United States are analyzed to reconcile differences in recent studies and to refine our knowledge of supercell environments. The large, storm-centric observation-based

Multispectral plasmonic supercells

Journal of Optics, 2018
Abstract By excitation of surface plasmon-polariton modes upon a multi-periodic metallic surface, we presented a new class of semiconductor-based multiband plasmonic supercell with potential application in trapping the light over a wide range of wavelengths and angles of incidence.

Non-supercell Tornadoes

Monthly Weather Review, 1989
Abstract Analyses of tornadoes that are not associated with supercells are presented. The database for this study was collected during CINDE (Convention INitiation and Downburst Experiment), a field project operated during the summer of 1987 in Colorado. A total of 27 visual vortices were studied.

Supercell's Supercell featuring Hatsune Miku

2017
The lead singer on Supercell’s eponymous first album is Hatsune Miku—a Vocaloid character created by Crypton Future Media with voice synthesizers. A virtual superstar, over 100,000 songs, uploaded mostly by fans, are attributed to her. Supercell is a Japanese creator music group with the composer Ryo leading ten artists, who design album illustrations ...

Properties of Negative Initial Leaders and Lightning Flash Size in a Cluster of Supercells

Journal of Geophysical Research - Atmospheres, 2018
Properties of negative initial leaders (NILs) and flash size in a cluster of supercells with generally inverted charge structure in Oklahoma on 10–11 May 2010 are examined, primarily using Lightning Mapping Array data.

Supercells Outcompete Their Neighbors

Science's STKE, 2004
Mutations that increase cell size or proliferation rates can alter organ size or organism size, or both. In mosaic organisms or tissues in which only a subset of the cells carry the mutation, the situation is more complex, and sometimes these animals or tissues can be of normal size.

Lightning and microphysics in a EULINOX supercell storm

Physics and Chemistry of the Earth, Part B: Hydrology, Oceans and Atmosphere, 2000
Abstract A combined analysis of data from a C-band polarization diversity Doppler radar and a 3D VHF interferometric lightning mapping system is presented for the 21 July 1998 EULINOX supercell thunderstorm. Its lower positive charge center emitted much more VHF radiation than expected from the well-known tripole concept.

The Merger of a Supercell and Squall Line in the Great Plains. 1: Initiation of the Supercell

Journal of Geophysical Research: Atmospheres
AbstractUsing a four‐dimensional variational data assimilation system that incorporates radar and surface observations, we investigated the initiation mechanism of a nocturnal supercell in the central Great Plains on 23 May 2020. This pristine convection occurred ahead of an eastward‐propagating squall line, despite the absence of discernible surface ...

Gold strip gratings with binary supercell

Optics Letters, 2013
In this Letter, the study of a periodic structure composed of gold strips arranged in double-period unit cells, in a symmetric and asymmetric environment, is reported. The spectral maps show that the formation of the plasmonic bandgap and the extraordinary optical transmission are subjected to the proportion between the strip widths. Moreover, when the

Invented Forces in Supercell Models

Journal of the Atmospheric Sciences, 2021
AbstractThis paper examines methods used in supercell models to maintain a steady, sheared, horizontally uniform environment with a three-force balance in the planetary boundary layer (PBL) and a two-force balance above it. Steady environments are maintained while ignoring the thermal-wind balance that permits large shear above the PBL.
