The Acoustic Nature of “Storm Nose”, “Supercell” Vortices and Tornadoes

open access: yesSIBERIAN JOURNAL OF PHYSICS, 2022
The process of cumulonimbus cloud Cb calvus formation in the middle latitudes of real atmosphere is analyzed in this work. Its transformation from initial lifecycle stage to “maturity” undergoes due to the formation of the waveguide called “aerial acoustic channel” in the troposphere near the level of temperature minimum that is close to 2 km altitude.

Pt Single‐Atom Activates Surface Lattice Oxygen for Enhanced Acetone Detection Mediated by the MvK Mechanism

open access: yesAdvanced Science, Volume 13, Issue 18, 27 March 2026.
A Pt single‐atom‐loaded CuO sensing material is developed for acetone detection, demonstrating remarkably enhanced sensing performance. The introduction of Pt single atoms effectively activates the lattice oxygen of the CuO support. A new sensing mechanism based on the Mars‐van Krevelen catalytic mechanism is proposed, offering new insights into the ...

Ni Single‐Atom Modulation of Ti‐O Covalency Boosts Ammonia Oxidation Electrocatalysis

open access: yesAdvanced Science, Volume 13, Issue 17, 23 March 2026.
A Ni single‐atom‐induced enhancement of Ti‐O covalency in Ni SAC@TiO2 generates abundant active sites and promotes selective NHx‐NHy mediated N2 evolution while suppressing poisonous NOx formation, achieving nearly doubled AOR activity with excellent durability.

Enhanced Polarimetric Radar Signatures above the Melting Level in a Supercell Storm

open access: yesJournal 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

Sustainable Framework for Thermoelectric Inorganic‐In‐Organic Superlattices With High Power Factor and Selective P‐ or N‐Type Doping

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
By multilayering poly(3,4‐ethylenedioxythiophene):polystyrene sulfonate with metal nanolayers into a superlattice structure, we report an enhancement to the thermoelectric performance of two orders of magnitude, achieving a peak power factor of 2800 µW m−1 K−2.

C-Band Dual-Doppler Retrievals in Complex Terrain: Improving the Knowledge of Severe Storm Dynamics in Catalonia

open access: yesRemote Sensing, 2020
Convective activity in Catalonia (northeastern Spain) mainly occurs during summer and autumn, with severe weather occurring 33 days per year on average. In some cases, the storms have unexpected propagation characteristics, likely due to a combination of

Structural, Superconducting and Magnetic Properties of Oxygen‐Annealed Fe1+yTe Thin Films

open access: yesAdvanced Physics Research, Volume 5, Issue 3, March 2026.
FeTe:Ox films exhibit exchange bias below their Néel temperatures, which coexists with superconductivity. STEM analysis reveals the structural changes induced by oxygen treatment. DFT calculations indicate that interstitial oxygen suppresses antiferromagnetism and promotes superconductivity.

Analysis and Forecast of a Tornadic Thunderstorm Using Multiple Doppler Radar Data, 3DVAR, and ARPS Model

open access: yesAdvances in Meteorology, 2013
A three-dimensional variational (3DVAR) assimilation technique developed for a convective-scale NWP model—advanced regional prediction system (ARPS)—is used to analyze the 8 May 2003, Moore/Midwest City, Oklahoma tornadic supercell thunderstorm. Previous

Investigating the Role of Climate Change in the 3 May 2025 Western Europe Hailstorm Using Atmospheric Analogs

open access: yesAtmospheric Science Letters, Volume 27, Issue 3, March 2026.
We analyzed the 3 May 2025 Paris hailstorm to assess climate change's influence using ERA5 data and analogue‐based attribution. Comparing present and past atmospheric patterns, we found that today's warmer climate shows stronger instability and energy, favoring large hail formation.
