Basic lightning flash properties derived from lightning mapping array data

open access: yes
The size and duration of lightning flashes are examined. Data from the Ebro Valley Laboratory Lightning Mapping Array is used as reference. Additional data from the VLF/LF LINET network is included.

Do the public take action when a severe snow warning is issued?

open access: yesWeather, EarlyView.
Extreme weather events pose significant risks to the population, making timely warnings essential for preparedness. The UK Met Office’s National Severe Weather Warning Service (NSWWS) has issued impact‐based alerts for over a decade, yet evaluations of their effectiveness remain limited.

What do we mean by ‘consistency’ in weather forecasts?

open access: yesWeather, EarlyView.
Weather forecast users often require forecasts to be ‘consistent’, yet the term is used to describe several different properties of forecast behaviour. This paper proposes a framework distinguishing different forms of consistency in weather forecast products, divided into cross‐product consistency (message, forecast narrative, value‐range and exact ...

Lightning Impulse Ageing of HDPE

open access: yes, 2009
This work is concerned with the hypothesis that lightning impulses can lead to accelerated ageing of extruded polymeric cables. The behaviour of an insulation material when suffering lightning impulses is different from that for DC or power frequency ...

Evaluation Methodology, Numerical Verification and Retrofilling Procedure for Power Transformers to Ensure K‐Class Flame Retardancy and Environmentally Friendly

open access: yesHigh Voltage, EarlyView.
ABSTRACT With increasing demands for fire safety and environmental friendliness, retrofilling transformers with alternative insulating liquids has become a growing trend. However, retrofilling power transformers remains uncertain, as more residual mineral oil compromises K‐class flame retardancy, and its impact on environmental performance has yet to ...
