Considering on return stroke current wave shape for tall objective cases [PDF]

2010 IEEE Student Conference on Research and Development (SCOReD), 2010
The return stroke current along the lightning channel for striking of the lightning to tall objective case is different from ground surface case with many factors affect this phenomenon. This study considers the engineering related to return stroke current models where the general equations are expressed and different models are generated.

Advances of Observation and Study on Tall-object Lightning in Guangzhou over the Last Decade

应用气象学报, 2020
Comparing to the ground or low-object, tall-object is more likely to reach the threshold for the initiation of leader on its top due to the distortion and enhancement of electric field, therefore tall-object is not only easier to get struck by downward ...

VERTICALITY ASSESSMENT OF THE OBJECTS WITH A CIRCULAR BASE: METHOD COMPARISON [PDF]

Geodetski Glasnik, 2021
The inclination is the most important criteria for determining stability of the object for objects for which the ratio of height and width is high (industrial chimneys, towers, tall buildings, etc.). In this paper, two methods for testing the verticality

Do metal objects such as mobile phones increase lightning risk?

Geomatics, Natural Hazards & Risk, 2021
This study has been carried out to test two hypotheses; whether a small metal object such as mobile phones in possession of a human body increases the chances of a direct lightning strike and whether a similar object increases the chances of a side flash.
