Rare Lightning and Convection Characteristics During Two Successive Tornadoes in Southern China

High Voltage, EarlyView.
ABSTRACT Systematic investigations into lightning characteristics of tornado storms in China remain scarce. This study comprehensively analyses rare lightning behaviour and overshooting top characteristics for two successive tornadoes during a long‐lived supercell in southern China on 27 April 2024.

Ray Tracing and Applications to an Evaporation Duct Model Based on Data from Oceanographic Buoy Sensors

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
The two-dimensional ray tracing method allows an easy and fast modeling of tropospheric propagation in the microwave frequency range. A version of this method that determines ray trajectories, amplitudes and delays of the electromagnetic field, as well ...

Method for calculating torsional oscillations in Earth’s atmosphere from NCEP/NCAR, MERRA-2, ECMWF ERA-40, and ERA-Interim

Solar-Terrestrial Physics, 2019
In this paper, we describe a method for calculating low-frequency zonal-mean zonal wind variations, which we call torsional oscillations. We compare the torsional oscillations calculated from the NCEP/NCAR reanalysis I, MERRA-2, ECWMF ERA-40, and ERA ...

Evaporation and Cold Pools Beneath Trade Cumulus Clouds

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract The sources of air and water vapor in the tropical trade‐wind Atlantic subcloud boundary layer (SBL) are analyzed using in situ measurements of temperature, specific humidity, and stable water isotopologues (HDO and H218O) from shipboard observations in January‐February 2020.

The Tropical Indo‐Pacific and North Atlantic Precursors for the Interannual Variation of Extreme Humid‐heat Days in the Yangtze River Basin

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Extreme humid‐heat events pose a major hazard across the Yangtze River Basin (YRB), yet their underlying mechanisms and seasonal predictability remain insufficiently understood. Here, using observational diagnostics and coupled model experiments, we identify three independent drivers in the tropical Indo‐Pacific and subtropical North Atlantic ...

Mechanisms of the QBO Influence on the Tropical Troposphere: Modulation by ENSO Conditions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract The Quasi‐Biennial Oscillation (QBO) is the dominant mode of tropical stratospheric variability that can influence tropospheric circulation and convection. El Niño‐Southern Oscillation (ENSO), which is the primary source of interannual variability in the tropical troposphere, can modulate both the QBO and its impact on the tropical troposphere.

Accessible Climate and Impact Model Output for Studying the Human and Environmental Impacts of Nuclear Conflict

Geoscience Data Journal, Volume 13, Issue 3, July 2026.
When a nuclear weapon is detonated in a region with sufficient fuel loading, the resulting firestorm can lift soot into the stratosphere, where it disperses globally over a few weeks. The soot, or black carbon, blocks sunlight, decreasing temperature and precipitation and depleting ozone.
