The 2026 cold wave brought northern Fennoscandia its coldest 2‐week period since 1987

Weather, EarlyView.
During late December 2025 and January 2026, a severe and long‐lasting cold wave affected northern Fennoscandia. In this article, we aim to quantify the extremity of the 2026 cold wave and evaluate the atmospheric conditions that led to the persistent cold anomalies.

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.

Ion‐Flow Field Modelling of ± 1100 kV Transmission Lines Under Strong‐Wind Scenarios Using the Multiple Relaxation Time Lattice Boltzmann Method

High Voltage, EarlyView.
ABSTRACT To solve the ion‐flow field of ultrahigh‐voltage direct current (UHVDC) transmission lines under strong‐wind scenarios, the multiple relaxation time lattice Boltzmann method (MRT‐LBM) is adopted. Compared with previous ion‐flow studies predominantly based on the single relaxation time LBM, the MRT‐LBM framework provides improved numerical ...

Mobile consumers influence the shoreward edge of intertidal seagrass ecosystems

Journal of Animal Ecology, EarlyView.
Ecological paradigms suggest that the environmentally stressful edge of a habitat is determined by physical factors. The work finds that, counter to these paradigms, an environmentally stressful edge can also be impacted by biotic interactions and are more complex than suggested.
