A Simplified Top-Oil Temperature Model for Transformers Based on the Pathway of Energy Transfer Concept and the Thermal-Electrical Analogy

Energies, 2017
This paper presents an alternative approach to determine the simplified top-oil temperature (TOT) based on the pathway of energy transfer and thermal-electrical analogy concepts.

Estimation of Lightning Activity of Squall Lines by Different Lightning Parameterization Schemes in the Weather Research and Forecasting Model

Remote Sensing, 2023
Based on three-dimensional lightning data and an S-band Doppler radar, a strong relationship was identified between lightning activity and the radar volume of squall lines. A detailed analysis of the squall line investigates the relationship following an

Spatiotemporal Characteristics of Development Speed of Downward Positive Cloud-to-ground Lightning Leader Channels in Guangzhou

应用气象学报
Positive cloud-to-ground (CG) natural lightning typically exhibits higher energy release than negative CG lightning, with greater peak current, longer duration, and larger charge transfer.

Differences in Optical Two-dimensional Morphological Characteristics of Downward Lightning Channels with Different Polarities

应用气象学报
Proportions of positive and negative cloud-to-ground (CG) natural lightning are approximately 10% and 90%, respectively. Although the frequency of positive CG lightning is relatively low, these events are more likely to produce high current peaks ...

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 ...

Luminosity and Current Characteristics of Metal-vaporized Channel of an Artificially Triggered Lightning

应用气象学报, 2023
Channel current is an important parameter of the lightning discharge, but it's difficult to be directly measured due to the randomness and instantaneity of the natural lightning. The channel luminosity, however, is relatively easier to obtain.

DEATH BY LIGHTNING. [PDF]

JAMA: The Journal of the American Medical Association, 1903
A powerful man, weighing 212 pounds, 36 years old, was struck by lightning. In about 10 or 15 minutes I found him deeply cyanosed, skin relaxed and cool and the heart beating feebly, but there was no visible respiration. I gave him hypodermic injections of strychnin, whisky and finally the normal salt solution, keeping up artificial respiration for ten
