Explainable Optimized LSTM Model for Sustainable Wind Power Forecasting in Smart Cities

International Journal of Intelligent Systems, Volume 2026, Issue 1, 2026.
Accurate wind‐power forecasting is essential for the successful integration of renewable energy into smart city grids. Traditional long short‐term memory (LSTM) networks face significant challenges in parameter optimization, leading to suboptimal forecasting performance.

Comparative Study of Upward Leader Inception During the Initial Stage of Negative and Positive Altitude‐Triggered Lightning

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Comparative analysis of positive and negative altitude‐triggered lightning striking a 30‐m tower beneath 35‐m floating wires reveals detailed bidirectional leader processes. It provides the first observational evidence of bidirectional leader behavior in positive altitude‐triggered lightning and highlights the connection process's driving ...

Oxychlorine Species on Mars: A Review

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Oxychlorine species (mainly perchlorate and chlorate) have been identified at multiple locations on the surface of Mars by both orbiter and in situ rovers. They have also been found in martian meteorites. Cl‐isotopes in meteoritic minerals suggest that an oxychlorine cycle has been operating on the martian surface for the last ∼4 billion years.

Study on Transient Overvoltage and Surge Arrester Electrical Stresses in Offshore Wind Farms Under Multiple Lightning Strokes

Journal of Marine Science and Engineering
Lightning strikes are a major cause of wind turbine (WT) damage, with approximately 80% of cloud-to-ground lightning strikes exhibiting a multi-stroke characteristic. Therefore, studying the transient overvoltages induced by multiple lightning strokes is

The attachment process of rocket‐triggered lightning dart‐stepped leaders [PDF]

Journal of Geophysical Research: Atmospheres, 2016
AbstractTime‐correlated 1.54 µs high‐speed video frames, channel‐base current and current derivative (dI/dt), and electric field derivative (dE/dt) measurements are used to analyze the attachment process of triggered lightning dart‐stepped leaders. Lengths, speeds, and durations of the upward‐connecting positive leaders propagating from the launching ...

The communication of volcano information in New Zealand – a narrative review

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 4, Page 591-608, December 2025.
ABSTRACT Communication of volcano information is critical for effective volcanic risk management. A variety of information is communicated to inform decisions and guide actions for planning, preparedness, and response. Such information needs to be reliable, and fit‐for‐purpose across different stages of volcanic activity (quiescence, unrest, short or ...
