Polarimetric and Electrical Characteristics of a Lightning Ring in a Supercell Storm
Monthly Weather Review, 2010 Abstract On 30 May 2004, a supercell storm was sampled by a suite of instrumentation that had been deployed as part of the Thunderstorm Electrification and Lightning Experiment (TELEX). The instrumentation included the Oklahoma Lightning Mapping Array (OK-LMA), the National Severe Storms Laboratory S-band Weather Surveillance Radar-1988 ...

The Impact of a Stochastically Perturbing Microphysics Scheme on an Idealized Supercell Storm [PDF]
Monthly Weather Review, 2017 Abstract The concept of stochastic parameterization provides an opportunity to represent spatiotemporal errors caused by microphysics schemes that play important roles in supercell simulations. In this study, two stochastic methods, the stochastically perturbed temperature tendency from microphysics (SPTTM) method and the stochastically ...

A new scale‐selective measure of curvature for meteorological fields
Quarterly Journal of the Royal Meteorological Society, EarlyView.We introduce a novel diagnostic called curvature using radial variation (CURV) that quantifies the local cyclonic or anticyclonic curvature of mean‐sea‐level pressure or geopotential height gridded fields over selected scales. A depiction of how CURV values relate to differing cyclonic curvature is shown in the figure.

Using Remote and in situ Observations from TORUS to Investigate a Preexisting Airmass Boundary and its Influence on a Tornadic Supercell on 28 May 2019 [PDF]
, 2022 During the 2019 field phase of Targeted Observation by Radars and UAS of Supercells (TORUS), a preexisting airmass boundary was sampled on 28 May 2019 in north-central Kansas in close proximity to a tornadic supercell.

Quarterly Journal of the Royal Meteorological Society, EarlyView.We explore the relationship between dryline intensity, convective activity, and the regional circulation over southern Africa during summer by comparing weak and strong convective drylines with each other. We find that strong drylines result in stronger convection with up to 3.6 times more lightning strokes adjacent to the dryline than on weak dryline ...

Enhanced Polarimetric Radar Signatures above the Melting Level in a Supercell Storm
Journal of Applied Meteorology, 2002 The dataset analyzed is the first simultaneous in-situ and radar survey of phenomena associated with observed "columns" of differential reflectivity Z/sub dr/ and specific differential phase K/sub dp/ in a supercell storm. Further, no in situ measurements in regions of such enhanced Z/sub dr/ and K/sub dp/ have ever been reported. The measurements were

Liquid‐Processed 2D Aromatic Amorphous Carbon: Defect Engineering and Universal Transport Scaling
Small, EarlyView.Liquid‐processed graphene oxide (GO) thin films undergo a controllable crystalline–to–amorphous transition driven by thermal quenching. By kinetically tuning oxygen‐driven defect formation during reduction, scalable 2D aromatic amorphous carbon phases are stabilized, directly linking nanoscale disorder and defect topology to electronic transport ...
