Leader Propagation Characteristics Under Positive Lightning Impulse Voltages

IEEE Access
Lightning strikes on transmission lines often generate overvoltage, which is the primary reason for insulator string flashover. This overvoltage, with a rapid rise time of just a few microseconds, causes leader propagation characteristics to differ ...

Governing Positive Energy Districts: The Role of Legitimation and Identity Across Residential and Industrial Contexts

Environmental Policy and Governance, Volume 36, Issue 4, Page 751-767, August 2026.
ABSTRACT Increasing electricity demand from data centres, industrial applications, electric vehicles and domestic heating is creating pressure to develop electricity systems in many parts of the world, but especially in Western countries. In response to challenges such as grid congestion, interconnection queues and climate‐related hazards, network ...

Trends in thunderstorm days, lightning activity, squalls and the environmental factors in Hong Kong

Weather, Volume 81, Issue 8, Page 248-257, August 2026.
This study analyses trends in Hong Kong's convective weather using long‐term observer‐based and shorter‐term instrument‐based data. Annual thunderstorm days increased significantly by 1.9 days decade−1 in 1947–2024, notably in June–September, consistent with increasingly favourable warm‐season environments for thunderstorms.

Study on temperature rise prediction of ZnO varistors under multiple lightning strikes based on BP neural network and microscopic

High Temperature Materials and Processes
ZnO varistors are widely used in the field of lightning protection. After being struck by lightning, ZnO varistors absorb heat, which can lead to temperature rise and even damage, posing a serious safety threat to electrical safety.

Democratizing Hydroclimate Science for Just and Resilient Futures

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Hydroclimatic extremes are intensifying, escalating risks to ecosystems, infrastructure, and vulnerable communities. Rapid technological innovation and scientific discovery offer powerful tools to address these challenges, yet a gap remains between hydroclimate knowledge production and its use in decision‐making.

The loss of an Indigenous‐maintained She‐Oak woodland in southeast Australia

Geographical Research, Volume 64, Issue 3, August 2026.
A 2600‐year multi‐proxy palaeoecological record (pollen, charcoal, and sediment) from Balfour Swamp, east Gippsland, reveals the persistence of an open, grassy She‐Oak woodland maintained by GunaiKurnai. This vegetation community, resilient to climatic variability and fire, was lost following the disruption of Aboriginal land management and replaced by
